中英文对照外翻译Basic knowledge of transducersA transducer is a device which converts the quantity being measured into an optical, mechanical, or-more commonly-electrical signal. The energy-conversion process that takes place is referred to as transduction.Transducers are classified according to the transduction principle involved and the form of the measured. Thus a resistance transducer for measuring displacement is classified as a resistance displacement transducer. Other classification examples are pressure bellows, force diaphragm, pressure flapper-nozzle, and so on.1、Transducer ElementsAlthough there are exception ,most transducers consist of a sensing element and a conversion or control element. For example, diaphragms,bellows,strain tubes and rings, bourdon tubes, and cantilevers are sensing elements which respond to changes in pressure or force and convert these physical quantities into a displacement. This displacement may then be used to change an electrical parameter such as voltage, resistance, capacitance, or inductance. Such combination of mechanical and electrical elements form electromechanical transducing devices or transducers. Similar combination can be made for other energy input such as thermal. Photo, magnetic and chemical,giving thermoelectric, photoelectric,electromaanetic, and electrochemical transducers respectively.2、Transducer SensitivityThe relationship between the measured and the transducer output signal is usually obtained by calibration tests and is referred to as the transducer sensitivity K1= output-signal increment / measured increment . In practice, the transducer sensitivity is usually known, and, by measuring the output signal, the input quantity is determined from input= output-signal increment / K1.3、Characteristics of an Ideal TransducerThe high transducer should exhibit the following characteristicsa) high fidelity-the transducer output waveform shape be a faithful reproduction of the measured; there should be minimum distortion.b) There should be minimum interference with the quantity being measured; the presence of the transducer should not alter the measured in any way.c) Size. The transducer must be capable of being placed exactly where it is needed.d) There should be a linear relationship between the measured and the transducer signal.e) The transducer should have minimum sensitivity to external effects, pressure transducers,for example,are often subjected to external effects such vibration and temperature.f) The natural frequency of the transducer should be well separated from the frequency and harmonics of the measurand.4、Electrical TransducersElectrical transducers exhibit many of the ideal characteristics. In addition they offer high sensitivity as well as promoting the possible of remote indication or mesdurement. Electrical transducers can be divided into two distinct groups:a) variable-control-parameter types,which include:i)resistanceii) capacitanceiii) inductanceiv) mutual-inductance typesThese transducers all rely on external excitation voltage for their operation.b) self-generating types,which includei) electromagneticii)thermoelectriciii)photoemissiveiv)piezo-electric typesThese all themselves produce an output voltage in response to the measurand input and their effects are reversible. For example, a piezo-electric transducer normally produces an output voltage in response to the deformation of a crystalline material; however, if an alternating voltage is applied across the material, the transducer exhibits the reversible effect by deforming or vibrating at the frequency of the alternating voltage.5、Resistance TransducersResistance transducers may be divided into two groups, as follows:i) Those which experience a large resistance change, measured by using potential-divider methods. Potentiometers are in this group.ii)Those which experience a small resistance change, measured by bridge-circuit methods. Examples of this group include strain gauges and resistance thermometers.5.1 PotentiometersA linear wire-wound potentiometer consists of a number of turns resistance wire wound around a non-conducting former, together with a wiping contact which travels over the barwires. The construction principles are shown in figure which indicate that the wiperdisplacement can be rotary, translational, or a combination of both to give a helical-type motion. The excitation voltage may be either a.c. or d.c. and the output voltage is proportional to the input motion, provided the measuring device has a resistance which is much greater than the potentiometer resistance.Such potentiometers suffer from the linked problem of resolution and electrical noise. Resolution is defined as the smallest detectable change in input and is dependent on thecross-sectional area of the windings and the area of the sliding contact. The output voltage is thus a serials of steps as the contact moves from one wire to next.Electrical noise may be generated by variation in contact resistance, by mechanical wear due to contact friction, and by contact vibration transmitted from the sensing element. In addition, the motion being measured may experience significant mechanical loading by the inertia and friction of the moving parts of the potentiometer. The wear on the contacting surface limits the life of a potentiometer to a finite number of full strokes or rotations usually referred to in the manufacture’s specification as the ‘number of cycles of life expectancy’, a typical value being 20*1000000 cycles.The output voltage V0 of the unload potentiometer circuit is determined as follows. Let resistance R1= xi/xt *Rt where xi = input displacement, xt= maximum possible displacement, Rt total resistance of the potentiometer. Then output voltage V0= V*R1/(R1+( Rt-R1))=V*R1/Rt=V*xi/xt*Rt/Rt=V*xi/xt. This shows that there is a straight-line relationship between output voltage and input displacement for the unloaded potentiometer.It would seen that high sensitivity could be achieved simply by increasing the excitation voltage V. however, the maximum value of V is determined by the maximum power dissipation P of the fine wires of the potentiometer winding and is given by V=(PRt)1/2 .5.2 Resistance Strain GaugesResistance strain gauges are transducers which exhibit a change in electrical resistance in response to mechanical strain. They may be of the bonded or unbonded variety .a) bonded strain gaugesUsing an adhesive, these gauges are bonded, or cemented, directly on to the surface of the body or structure which is being examined.Examples of bonded gauges arei) fine wire gauges cemented to paper backingii) photo-etched grids of conducting foil on an epoxy-resin backingiii)a single semiconductor filament mounted on an epoxy-resin backing with copper or nickel leads.Resistance gauges can be made up as single elements to measuring strain in one direction only,or a combination of elements such as rosettes will permit simultaneous measurements in more than one direction.b) unbonded strain gaugesA typical unbonded-strain-gauge arrangement shows fine resistance wires stretched around supports in such a way that the deflection of the cantilever spring system changes the tension in the wires and thus alters the resistance of wire. Such an arrangement may be found in commercially available force, load, or pressure transducers.5.3 Resistance Temperature TransducersThe materials for these can be divided into two main groups:a) metals such as platinum, copper, tungsten, and nickel which exhibit and increase in resistance as the temperature rises; they have a positive temperature coefficient of resistance.b) semiconductors, such as thermistors which use oxides of manganese, cobalt, chromium, or nickel. These exhibit large non-linear resistance changes with temperature variation and normally have a negative temperature coefficient of resistance.a) metal resistance temperature transducersThese depend, for many practical purpose and within a narrow temperature range, upon the relationship R1=R0*[1+a*(b1-b2)] where a coefficient of resistance in ℃-1,and R0 resistance in ohms at the reference temperature b0=0℃ at the reference temperature range ℃.The international practical temperature scale is based on the platinum resistance thermometer, which covers the temperature range -259.35℃ to 630.5℃.b) thermistor resistance temperature transducersThermistors are temperature-sensitive resistors which exhibit large non-liner resistance changes with temperature variation. In general, they have a negative temperature coefficient. For small temperature increments the variation in resistance is reasonably linear; but, if large temperature changes are experienced, special linearizing techniques are used in the measuring circuits to produce a linear relationship of resistance against temperature.Thermistors are normally made in the form of semiconductor discs enclosed in glass vitreous enamel. Since they can be made as small as 1mm,quite rapid response times are possible.5.4 Photoconductive CellsThe photoconductive cell , uses a light-sensitive semiconductor material. The resistance between the metal electrodes decrease as the intensity of the light striking the semiconductor increases. Common semiconductor materials used for photo-conductive cells are cadmium sulphide, lead sulphide, and copper-doped germanium.The useful range of frequencies is determined by material used. Cadmium sulphide is mainly suitable for visible light, whereas lead sulphide has its peak response in the infra-red regionand is, therefore , most suitable for flame-failure detection and temperature measurement. 5.5 Photoemissive CellsWhen light strikes the cathode of the photoemissive cell are given sufficient energy to arrive the cathode. The positive anode attracts these electrons, producing a current which flows through resistor R and resulting in an output voltage V.Photoelectrically generated voltage V=Ip.RlWhere Ip=photoelectric current(A),and photoelectric current Ip=Kt.BWhere Kt=sensitivity (A/im),and B=illumination input (lumen)Although the output voltage does give a good indication of the magnitude of illumination, the cells are more often used for counting or control purpose, where the light striking the cathode can be interrupted.6、Capacitive TransducersThe capacitance can thus made to vary by changing either the relative permittivity, the effective area, or the distance separating the plates. The characteristic curves indicate that variations of area and relative permittivity give a linear relationship only over a small range of spacings. Thus the sensitivity is high for small values of d. Unlike the potentionmeter, the variable-distance capacitive transducer has an infinite resolution making it most suitable for measuring small increments of displacement or quantities which may be changed to produce a displacement.7、Inductive TransducersThe inductance can thus be made to vary by changing the reluctance of the inductive circuit. Measuring techniques used with capacitive and inductive transducers:a)A.C. excited bridges using differential capacitors inductors.b)A.C. potentiometer circuits for dynamic measurements.c) D.C. circuits to give a voltage proportional to velocity for a capacitor.d) Frequency-modulation methods, where the change of C or L varies the frequency of an oscillation circuit.Important features of capacitive and inductive transducers are as follows:i)resolution infiniteii) accuracy+- 0.1% of full scale is quotediii)displacement ranges 25*10-6 m to 10-3miv) rise time less than 50us possibleTypical measurands are displacement, pressure, vibration, sound, and liquid level.8、Linear Variable-differential Ttransformer9、Piezo-electric Transducers10、Electromagnetic Transducers11、Thermoelectric Transducers12、Photoelectric Cells13、Mechanical Transducers and Sensing Elements传感器的基础知识传感器是一种把被测量转换为光的、机械的或者更平常的电信号的装置。

They can turn all kinds of physical information, according to certain rules, into measurable electrical signal. Based on the changes of electrical signals we measured, and the related physical information relationship, we can gain the measured physical information changes or size.According to the working principle of the sensor, we can divide the sensors into many types, such as photoelectric sensor, charge sensors, potential type sensor, semiconductor sensor, the electricity sensor, magnetic sensor, resonant sensor, electric chemical formula sensor etc.Hall sensor is the use of hall element based on the Hall effect principle, which can concert the physical information, such as current, magnetic field, the displacement, pressure, etc, into electromotive force output. It belongs to the potential type sensor. At present, this kind of sensor is mainly hall integrated circuit and the core unit is based on the Hall effect, which is made through the integrated circuit technology. So it is not only a kind of integrated circuit, but a kind of magnetic sensor.According to the actual application, this article is mainly about the hall current sensor.1.Hall effectWhen we place a metal or semiconductor wafer in a magnetic field, and if there is a current through it, it will produce electromotive force in the perpendicular direction of the electric and magnetic field, calling this kind of physical phenomenon Hall effect.Figure 1 Hall effect principle diagramUnder the action of the Lorentz force generated in the magnetic field, the carrier of energized semiconductor chip, deflect and accumulate respectively on both sides of the chip, thus forming a electric field, called the Hall electric field. Hall electric field produces electric field force which is contrary to the Lorentz force, hindering carrier to continue to pile up, until the hall electric field force equal with the Lorentz force. At this time, it will set up a stable voltage on both sides of the chip, and this is the hall voltage.2.Hall current sensorAlong with the urban population and the expansion of the construction scale of the city, and the increasing of all kinds of electric equipment, power consumption is bigger and bigger. The power supply equipment of the city often overload , while power environment becomes more and more bad, the "test" to the power being more and more serious. Thus, the problems in the power supply come out more and more apparently . Now, small power supply equipment has been combined with more and more new technology. For example, switch power supply, hard switch, soft switch, parameter voltage regulator, linear feedback voltage regulator, magnetic amplifier technology, numerical control pressure regulation, PWM, SPWM, electromagnetic compatibility, etc. The actual demands directly promote power technology development and progress. In order to detect and display current automatically, and the automatic protection function and more advanced intelligent control when the harm such as over current, over voltage occurs, the power supply technology with sensing detection, sensing sampling and sensing protection becomes a trend. Sensors of detecting current or voltage, called Hall current sensor, come into being, and quickly become the favorite of the designers of the power supply in our country.2.1 The performance characteristics of Hall current sensorHall current sensor has superior performance, and it is a kind of advanced electric detecting element, which can isolate the main circuit loop and electronic control circuit. It has all the advantages of transformers and shunts, and at the same time, overcomes their disadvantages (transformer can be only applied to the power frequency measurement, 50 Hz; shunt is unable to do isolation measurement). Using the same one hall current sensor module detecting element not only can test AC, but also can detect DC, even can detect transient peak. It has the following performance characteristics.●Measure the arbitrary waveform current, such as DC, AC, and even to transient peak parameters measurement;●High precision. General Hall current sensor module’s precision in the work area is higher than 1%, and the precision is suitable for any waveform measurement;●The linearity is better than 0.5%;●Good dynamic performance. The dynamic response time of general Hallsensor module is less than 7μs, and the tracking speed di/dt is above 50A/μs;●Working band wide. It can work in the frequency range from 0 to 20 KHZ very well;●Strong overload ability. Wide measurement range(0~±10000A);●High reliability. The average trouble-free working is more than 5 x 10000 hours;●Small size, light weight, easy to install and it will not bring any loss to the system.In view of the above high performance characteristics, the Hall current sensors gain the wide applications.2.2 The principle of Hall current sensorHall current sensor can measure all kinds of current, from DC to AC of dozens of thousand Hertz. The basis principle of working is mainly Hall effect principle.2.2.1Open loop current sensorWhen the primary side current Ip flows through a long wire, it will produce a magnetic field around the wire, and the size of the magnetic field is proportional to the current through the wire, the magnetic field gathering inside the magnetic ring. Through the Hall element between the magnetic ring gap, it measures and output the amplification result, the output voltage Vs reflecting the primary side current Ip accurately. The general rated output is 4V.Figure 2 open loop current sensor principle diagramThis way has many advantages. It has simple structure and is measurable DC, AC and various waveform current. Besides, the precision and linearity of the measurement result is higher. But its measuring range and bandwidth are limited to a certain extent. In this application, Hall device is a magnetic detector, It detects the magnetic induction intensity in core magnetic circuit air gap. After the currentincreases, core may reach saturation; Along with the frequency increasing, the eddy current loss and hysteresis loss of the core also will increase. These will influence on the measuring accuracy.Through this method, the result will output in the form of voltage signal and it’s easy to come true in the attachment.2.2.2Closed loop current sensorFigure 3 closed loop current sensor principle diagram Magnetic balanced current sensor Is also called compensation sensor. It means th e magnetic field which is produced by the primary side current Ip in poly beads space of generated was compensated with the magnetic fields which is produced by a secon dary coil current. Its offset current Is an accurate reflection of the original edge curren t Ip, so that the hall device stay in the detecting zero flux working condition.Closed loop current sensor is also called compensation sensor. It means the magnetic field which is generated by the primary side current Ip in poly beads space was compensated through the magnetic fields which is generated by a secondary coil current. Its offset current Is reflects the primary side current Ip accurately, so that the Hall device stay in the detecting zero flux working condition.The specific work process of the magnetic balanced current sensor is: when a current flows through the main circuit, the magnetic field generated on the wires is gathered by poly beads and inducted to the hall device, using the output signal to drive power tube and make it conduct, so that we can get a compensation current Is. The current then produce a magnetic field through multicircuit winding, contrary to the one that generated by the measured current, thus compensating the original magnetic field and making the Hall device’s output decrease gradually.When Ip becomes the same as the magnetic fields produced by the number of turns multiplication, Is will no longer increase. At the time, the Hall device can instruct thezero flux. and we can test Ip though Is. When Ip changes, the balance will be damaged and the Hall device will have a output signal, so, then it will repeat the above process to achieve balance again. Any changes of the measured current will disrupt the balance. Once the magnetic field is out of balance, Hall device will have signal output. After the power amplifier, there will have corresponding current through the secondary winding to compensate the unbalanced magnetic field immediately. The time for magnetic field to change from unbalance to balance again needs less than 1 μ s in theory. This is a dynamic balance process. Therefore, from the macroscopic point of view, the ampere-turns number of the secondary compensation current is the same as the ampere turns of primary measured current in any time.When it becomes balance, Hall device will stay in zero flux state. The magnetic induction intensity of the core is extremely low (ideal state should be 0).It won’t make the core saturation, and also won't produce big hysteresis loss or eddy current loss. Choosing the core materials and line element properly can make out excellent zero magnetic power circuit sensors.The output that measured in this way will be the current signal. If you want the voltage signal, you can connect a load at the output, and then it can be converted into voltage output.2.3 The application of Hall current sensor in intelligent power gridBecause the Hall current sensor can measure all kinds of current and it has a very big measuring range, high precision, good linearity, and ease of installation, so it has a very widely used. Here is the main explanation in the application of intelligent power grid.Along with the vigorous development of the modern society, not the industrial electricity, but life electricity increases in a sharp, making all kinds of work constantly increase which greatly increase the burden of the staff. In order to have a reasonable electricity distribution, as well as complete circuit fault detection more efficiently, we use the Hall current sensor in power grid, along with all kinds of infrastructure, to realize the intelligent power network, so as to realize the high efficiency utilization of electricity.Because the installation of Hall current sensor is simple, we articulate hall current sensor module directly in measuring circuit, if enough, covering the area is quite large, so that it can gain the current information of each branch. Complementary with wireless communication module, it can transmit the measured signal to console in time. In console, we can process these signals very well, and then accurately obtain the whole grid electricity information at this time, so that we can distribute the electricity reasonably.In a period of time, if some branches broke down, we only need to operate the console and inquiry those abnormal current detection signal. Then, according to relevant position information, we can quickly narrow the scope of the failure, so as to realize efficient troubleshooting and solving.In our experiment, we adapt the open loop current sensor, CS020G. Its circuit connection diagram is shown in figure 4:Figure 4 Hall current sensor connection diagram in the circuitFigure 5 Hall sensor current application schematic diagram3.SummaryWith the research development, the use of the sensor will be more frequent and its function and integration will also be a more powerful. In measuring accuracy, flexibility, etc, they will also have a good ascension. Although the two Hall current sensors mentioned above meet the accuracy of measurement and linear degrees in a certain extent, they require magnetic field and Hall element vertical. So we must increase beads, this directly leads to the increase of the volume. In addition, they are sensitive to the variation of the temperature, and output voltage is also too small. Therefore, in many aspects, they need to compensate and improvement. High demands promote the development of the sensor.霍尔电流传感器及其应用在现代社会中,信息化的需求越来越庞大,传感器的信息采集中发挥了重要作用。

. sensorssensors(English name: transducer/sensor) is a kind of detection device, can feel the measured information, and will feel information transformation according to certain rule become electrical signal output, or other form of information needed to satisfy the information transmission, processing, storage, display, record and control requirements.Sensor's features include: miniaturization, digital, intelligent, multi-functional, systematic and network. It is the first step of automatic detection and automatic control. The existence and development of the sensor, let objects have sensory, such as touch, taste and smell let objects become live up slowly. Usually according to its basic cognitive functions are divided into temperature sensor, light sensor, gas sensor, force sensor, magnetic sensor, moisture sensor, acoustic sensor, radiation sensitive element, color sensor and sensor etc. 10 major categories.temperature transducerTemperature sensors (temperature transducer) refers to can feel temperature translates into usable output signal of the sensor. The temperature sensor is the core part of the temperature measuring instrument, wide variety. According to measuring methods could be divided into two types: contact and non-contact, according to the sensor material and electroniccomponent features divided into two categories, thermal resistance and thermocouple.1 principle of thermocoupleThermocouple is composed of two different materials of metal wire, the welded together at the end. To measure the heating part of the environment temperature, can accurately know the temperature of the hot spots. Because it must have two different material of the conductor, so called the thermocouple. Different material to make the thermocouple used in different temperature range, their sensitivity is also each are not identical. The sensitivity of thermocouple refers to add 1 ℃ hot spot temperature changes, the output variation of potential difference. For most of the metal material support thermocouple, this value about between 5 ~ 40 microvolt / ℃.As a result of the thermocouple temperature sensor sensitivity has nothing to do with the thickness of material, use very fine material also can make the temperature sensor. Also due to the production of thermocouple metal materials have good ductility, the slight temperature measuring element has high response speed, can measure the process of rapid change.Its advantages are:(1)high precision measurement. Because of thermocouple direct contact with the object being measured, not affected by intermediate medium.(2)the measurement range. Commonly used thermocouple from 1600 ℃to 50 ℃~ + sustainable measurement, some special thermocouple minimum measurable to - 269 ℃(e.g., gold iron nickel chrome), the highest measurable to + 2800 ℃ (such as tungsten rhenium).(3) simple structure, easy to use. Thermocouple is usually composed of two different kinds of metal wire, but is not limited by the size and the beginning of, outside has protective casing, so very convenient to use. The thermocouple type and structure of the form.2. The thermocouple type and structure formation(1)the types of thermocoupleThe commonly used thermocouple could be divided into two types: standard thermocouple and non-standard thermocouple. Standard thermocouple refers to the national standard specifies its thermoelectric potential and the relationship between temperature, permissible error, and a unified standard score table of thermocouple, it has with matching display instrument to choose from. Rather than a standard thermocouple or on the order of magnitude less than the range to use standardized thermocouple, in general, there is no uniform standard, it is mainly used for measurement of some special occasions.Standardized thermocouple is our country from January 1, 1988, thermocouple and thermal resistance of all production according to IEC international standard, and specify the S, B, E, K, R,J, T seven standardization thermocouple type thermocouple for our country unified design.(2)to ensure that the thermocouple is reliable, steady work, the structure of thermocouple requirements are as follows:①of the two thermocouple thermal electrode welding must be strong;②two hot electrode should be well insulated between each other, in case of short circuit;③compensation wires connected to the free cod of a thermocouple to convenient and reliable;④protect casing thermal electrodes should be able to make sufficient isolation and harmful medium.3.The thermocouple cold end temperature compensationDue to the thermocouple materials are generally more expensive (especially when using precious metals), and the temperature measurement points are generally more far, the distance to the instrument in order to save materials, reduce cost, usually adopt the compensating conductor) (the free end of the cold junction of the thermocouple to the steady control of indoor temperature, connected to the meter terminals. It must be pointed out that the role of the thermocouple compensation wire extension hot electrode, so that only moved to the control room of the cold junction of the thermocouple instrument on the terminal, it itself does not eliminate the cold end temperature change on the influence of temperature, cannot have the compensation effect. So, still need to take some of the other correction method to compensate of the cold end temperature especially when t0 indicates influence on measuring temperature 0 ℃.Must pay attention to when using thermocouple compensating conductor model match, cannot be wrong polarity, compensation conductor should be connected to the thermocouple temperature should not exceed 100 ℃.传感器传感器(名称:transducer/sensor)是一种检测装置,能感受到被测量的信息,并能将感受到的信息,按一定规律变换成为电信号或其他所需形式的信息输出,以满足信息的传输、处理、存储、显示、记录和控制等要求。
