dsc2型称重式降水传感器测量原理
DSC2型称重式降水传感器是一种用于测量降水量的设备。

它
的测量原理基于称重原理和降水的质量与液体体积的关系。

该传感器由一个空心的圆柱形外壳和内部的电子秤组成。

外壳的顶部有一个开口用于接收降水，而底部有一个称重传感器用于测量降水的质量。

在降水过程中，雨水进入传感器的顶部开口并通过重力作用进入内部的空心圆柱。

同时，称重传感器开始测量降水的质量。

由于降水的密度可以认为是恒定的，降水的质量与体积之间存在着固定的关系。

因此，测量降水的质量可以间接获得降水的体积。

传感器内部的电子秤通过测量降水的质量变化来计算降水的体积。

这些测量结果可以通过传感器的输出接口传输给外部设备进行数据处理和记录。

总结起来，DSC2型称重式降水传感器利用称重原理和降水的
质量与液体体积的关系来测量降水量。

这种传感器具有简单、准确和可靠的特点，被广泛应用于气象观测、水文监测等领域。

霍尔传感器测速原理：电流的测量采用磁平衡式霍尔电流传感器传感器可测量从直流到100kHz的交流量在自动测控系统中,常需要测量和显示有关电参量。

目前大多数测量系统仍采用变压器式电压、电流互感器,由于互感器的非理想性,使得变比和相位测量都存在较大的误差,常需要采用硬件或软件的方法补偿,从而增加了系统的复杂性。

采用霍尔检测技术,可以克服互感器这些缺点,能测量从直流到上百千赫兹的各种形状的交流信号,并且达到原副边不失真传递,同时又能实现主电路回路和电子控制电路的隔离,霍尔传感器的输出可直接与单片机接口。

因此霍尔传感器已广泛应用于微机测控系统及智能仪表中,是替代互感器的新一代产品。

在此提出了利用霍尔传感器对电参量特别是对高电压、大电流的参数的测量。

l测量原理1霍尔效应原理如图1所示,一个N型半导体薄片,长度为L,宽度为S,厚度为d,在垂直于该半导体薄片平面的方向上,施加磁感应强度为B的磁场,若在长度方向通以电流Ic则运动电荷受到洛伦兹力的作用,正负电荷将分别沿垂直于磁场和电流的方向向导体两端移动,并在导体两端形成一个稳定的电动势UH,这就是霍尔电动势(或称之为霍尔电压),这种现象称为霍尔效应。

霍尔电压的大小UH=RIB/d=KHICB,其中R为霍尔常数；KH为霍尔元件的乘积灵敏度。

2用霍尔传感器测量电参量的原理由霍尔电压公式可知：对于一个成型的霍尔传感器,乘积灵敏度KH是一恒定值,则UH∝ICB,只要通过测量电路测出UH的大小,在B和IC 两个参数中,已知一个,就可求出另一个,因而任何可转换成B或J的未知量均可利用霍尔元件来测量,任何转换成B和I乘积的未知量亦可进行测量。

电参量的测量就是根据这一原理实现的。

若控制电流IC为常数，磁感应强度B与被测电流成正比，就可以做成霍尔电流传感器测电流，若磁感应强度B为常数，IC与被测电压成正比，可制成电压传感器测电压，利用霍尔电压、电流传感器可测交流电的功率因数、电功率和交流电的频率。

外文资料(英文)Sensor is one kind component which can tansform the physical quantity, chemistry quantity and the biomass into electrical signal. The output signal has the different forms like the voltage, the electric current, the frequency, the pulse and so on, which can satisfy the signal transmiss ion, processing, recording, demonstration and control demands. So it is the automatic detectio n system and in the automatic control industry. If automatic Technology is used wider, then se nsor is more important. In information age, the information industry includs information gatherin g, transmission, process three parts, namely sensor technology, communication, computer te chnology. Because of ultra large scale integrated circuit’s rapid development after having been developed ,Modern computer technology and communication, not only requests sensor preci sion, reliability, speed of response and gain information content request more and more high, b ut also requests its cost to be inexpensive. The obvious traditional sensor is eliminated gradual ly because of the function, the characteristic, the volume, the cost and so on. As world develo p many countries are speeding up to the sensor new technology’s research and the developm ent, and all has obtained the enormous breakthrough. Now the sensor new technology develop ment, mainly has following several aspects:Firstly, discovering and using.Using the physical phenomenon, the chemical reaction, the biological effect as the sensor p rinciple therefore the researches which discovered the new phenomenon and the new effect are the sensor technological improving ways .it is importantstudies to develope new sensor’s t he foundation. Japanese Sharp Corporation uses the superconductivity technology to develop successfully the high temperature superconductivity magnetic sensor and get the sensor techn ology significant breakthrough. Its sensitivity is so high and only inferior in the superconductivit y quantum interference component. Its manufacture craft is far simpler than the superconductiv ity quantum interference component. May use in magnetism image formation technology.So it has the widespread promoted value.Using the immune body and the antigen meets one another compound when the electrode surface.It can cause the electrode potential change and use this phenomenon to be possible to generate the immunity sensor. The immunity sensor makes with this kind of immune body ma y to some organism in whether has this kind of anti- original work inspection. Like may inspect somebody with the hepatitis virus immune body whether contracts the hepatitis, plays to is fast, the accurate role. The US UC sixth branch has developped this kind of sensor.Secondly, using the new material.The sensor material is the important foundation for sensor technology, because the materi als science is progressive and the people may make each kind of new sensor. For example ma king the temperature sensor with the high polymer thin film; The optical fiber can make the pre ssure, the current capacity, the temperature, the displacement and so on the many kinds of se nsors; Making the pressure transmitter with the ceramics. The high polymer can become the pr oportion adsorption and the release hydrone along with the environment relative humidity size. The high polymer electricity lies between the constant to be small, the hydrone can enhance the polymer the coefficient of dielectrical loss. Making the capacitor the high polymer dielectric m edium, determines the electric capacity capacity the change, then obtains the relative humidity. Making the plasma using this principle to gather the legitimate polystyrene film temperature se nsor below, it has the characteristic:Measured the wet scope is wide;The temperature range is wide, may reach -400 ℃ ~ +1,500 ℃;The speed of response is quick, is smaller than 1S;The size is small, may use in the small space measuring wet;The temperature coefficient is small.The ceramic electric capacity type pressure transmitter is one kind does not have the inter mediary fluid the dry type pressure transmitter. Uses the advanced ceramic technology, the he avy film electronic technology, its technical performance is stable, the year drifting quantity is s maller than 0.1%F.S, warm floats is smaller than ±0.15%/10K, anti- overloads strongly, may re ach the measuring range several hundred times. The survey scope may from 0 to 60mpa. German E+H Corporation and the American Kavlio Corporation product is at the leading positi on.The optical fiber application is send the material significant breakthrough, its uses in most e arly the optical communication techniques. In the optical communication use discovered works as environmental condition change and so on the temperature, pressure, electric field, magneti c field, causes the fiber optic transmission light wave intensity, the phase, the frequency, chang e and so on the polarization condition, the survey light wave quantity change, may know cause s these light wave physical quantity the and so on quantitative change temperature, pressure, electric field, magnetic field size, uses these principles to be possible to develop the optical fib er sensor. The optical fiber sensor and the traditional sensor compare has many characteristics : Sensitivity high, the structure simple, the volume small, anti-corrosive, the electric insulation g ood, the path of rays may be curving, be advantageous for the realization telemetering and so on. Optical fiber sensor Japan is in the advanced level. Like Idec Izumi Corporation and Sunx Corporation. The optical fiber send receiver and the integrated path of rays technology unify, a ccelerates the optical fiber sensor technology development. Will integrate the path of rays com ponent to replace the original optics part and the passive light component, enable the optical fi ber sensor to have the high band width, the low signal processing voltage, the reliability high, t he cost will be low.Third, micro machine-finishing technologyIn semiconductor technology processing method oxygenation, the photoetching, the prolifer ation, the deposition, the plane electron craft, various guides corrosion and steams plates, the sputtering thin film and so on, these have all introduced to the sensor manufacture. Thus has p roduced each kind of new sensor, like makes the silicon micro sensor using the semiconductor technology, makes the fast response using the thin film craft the gas to be sensitive, the wet s ensitive sensor, the use sputtering thin film craft system pressure transmitter and so on.The Japanese horizontal river company uses various guides corrosion technology to carry on the high accuracy three dimensional processing, the system helps the silicon resonance typ e pressure transmitter. The core partially presses two resonant Liang by the feeling which abov e the silicon diaphragm and the silicon diaphragm manufactures to form, two resonant Liang's f requency difference correspondence different pressure, measures the pressure with the frequency difference method, may eliminate the error which factor and so on ambient temperature bri ngs. When ambient temperature change, two resonant Liang frequency and the amplitude vari ation are same, after two frequency differences, its same change quantity can counterbalance mutually. Its survey most high accuracy may reach 0.01%FS.American Silicon Microstructure Inc.(SMI) the company develops a series of low ends, linea r in 0.1% to 0.In 65% scope silicon micro pressure transmitter, the lowest full measuring range is 0.15psi (1KPa), it makes take the silicon as the material, has the unique three dimensional st ructure, the light slight machine-finishing, makes the wheatstone bridge many times with the et ching on the silicon diaphragm, when above silicon chip stress, it has the distortion, the resista nce produces presses the anti- effect but to lose the bridge balance, the output and the pressu re becomes the proportion the electrical signalSuch silicon micro sensor is the front technology which now the sensor develops,Its essenti al feature is the sensitive unit volume is a micron magnitude,Is the traditional sensor several do zens, several 1%. In aspect and so on industry control, aerospace domain, biomedicine has th e vital role, like on the airplane the use may reduce the airplane weight, reduces the energy. A nother characteristic is can be sensitive is small surveyed, may make the blood pressure press ure transmitter.The Chinese aviation main corporation Beijing observation and control technical research i nstitute, the development CYJ series splashes thanks the membrane pressure transmitter is us es the ion sputtering craft to process the metal strain gauge, it has overcome the nonmetallic st rain gauge easily the temperature influence insufficiency, has the high stability, is suitable in ea ch kind of situation, is measured the medium scope widely, but also overcame the tradition lowl y to glue the precision which the type brought, sluggish big, shortcoming and so on slow chang e, had the precision high, the reliability is high, the volume small characteristic, widely used in domain and so on aviation, petroleum, chemical industry, medical service.Fourth, integrates the sensorIntegrates the sensor the superiority is the traditional sensor is unable to achieve, it is a sim ple sensor not merely, it in at the same time the auxiliary circuit part and send the part will integ rate on together the chip, will cause it to have the calibration, to compensate, from the diagnosi s and the network correspondence function, it might reduce the cost, the gain in yield, this kind of blood pressure sensor which American LUCAS, NOVASENSOR Corporation will develop, e ach week will be able to produce 10,000.Fifth, intellectualized sensorThe intellectualized sensor is one kind of belt microprocessor sensor, is achievement which the microcomputer and the sensor unifies, it has at the same time the examination, the judgm ent and the information processing function, compares with the traditional sensor has very man y characteristics:Has the judgment and the information processing function, can carry on the revision, the err or to the observed value compensates, thus enhancement measuring accuracy;May realize the multi-sensor multi parameters survey;Has from the diagnosis and from the calibration function, enhances the reliability;The survey data may deposit and withdraw, easy to operate;Has the data communication interface dci, can and the microcomputer direct communicatio n.The sensor, the signal adjustment electric circuit, the monolithic integrated circuit integratio n forms ultra large-scale integrated on a chip the senior intelligence sensor. American HONY WELL Corporation ST-3000 intelligence sensor, the chip size only then has 3×4×2mm3, uses t he semiconductor craft, makes CPU, EPROM, the static pressure, the differential pressure, the temperature on the identical chip and so on three kind of sensitive units.The intellectualized sensor research and the development, US is at the leading position. A merican Space Agency when development spaceship called this kind of sensor for the clever s ensor (Smart Sensor), on the spaceship this kind of sensor is extremely important. Our country in this aspect research and development also very backward, mainly is because our country s emiconductor integrated circuit technological level is limited.The sensor’s development is changing day after day since specially the 80's humanities ha ve entered into the high industrialization the information age, sensor technology to renewal, hig her technological development. US, Japan and so on developed country sensor technological development quickest, our country because the foundation is weak, the sensor technology co mpares with these developed countries has the big disparity. Therefore, we should enlarge to t he sensor engineering research, the development investment, causes our country sensor tech nology and the foreign disparity reduces, promotes our country instrument measuring applianc e industry and from the technical development.外文翻译(中文)传感器是一种能将物理量、化学量、生物量等转换成电信号的器件。
