®WIRINGUse 12 AWG wire maximum for electrical connections and 3/16˝ inner diameter rubber or plastic tubing for pneumatic connections. For your convenience we sell 3/16˝ I.D. rubber tubing, part number A-202, and 3/16˝ I.D. flexible vinyl tubing, part number A-220.See Figures 1 and 2 for wiring configurations and Figures 3 through 5for jumper designations.CAUTION•Ensure that the main supply pressure does not exceed 40 psi (276 kPa).•Ensure a minimum of 6 to 10 feet (1.8 to 3.0 m) of tubing between the transducer and the actuator.•For a 24 VAC supply voltage, ensure that the hot and neutral lines are not reversed. If more than one transducer is being powered from the same power supply, the hot and neutral lines should be the same for each transducer.* Do not connect 120 VAC to the electro-pneumatic transducer.Note:The transducer’s gage is for indication only. The transducer measures more precisely than what is displayed on the gage.WIRING DIAGRAMSFigures 1 and 2 illustrate typical wiring diagrams for the electro-pneumatic transducer.CAUTIONThis transducer contains a half-wave rectifier power supply and must not be powered from transformers powering other devices with non-isolated full-wave rectifier power supplies.ADJUSTMENTS - Jumper ConfigurationThe electro-pneumatic transducer is factory configured for a 4-20 mA input. To change the input, adjust the jumper settings as follows (see figures 3, 4 and 5.)©Copyright 2005Dwyer Instruments, Inc.Printed in U.S.A. 12/05FR# R1-443413-00TRANSDUCER OPERATION•Adjust the input signal to obtain a maximum output pressure for the appropriate range.•Ensure that the output is 15 or 20 psi (100 or 138 kPa).•Adjust the input signal to obtain a minimum output pressure.•Ensure that the output is 3 or 0 psi (20 or 0 kPa).CALIBRATIONAll electro-pneumatic transducers are factory calibrated to meet or exceed published specifications. If field adjustment is necessary, follow these instructions.1.Connect air to the Main port (see figure 6).2.Connect an accurate gage to the Branch port using a minimum of 6 to 10 feet (1.8 to3.0 m) of tubing.3.Connect the (+) and (–) terminals to an appropriate power source. The transducer can accept either a 24 VAC or VDC supply voltage. The maximum supply voltage should not exceed 30 VAC/VDC.4.Apply a low input signal to the (–) and (I) terminals (0 VDC or 4 mA).5.Adjust (Z) to obtain the desired low output pressure.6.Apply a high input signal to the (–) and (l) terminals (5/10 VDC or 20 mA).7.Adjust (S) to obtain the desired high output pressure.8.The zero and span controls are slightly interactive, so steps 4 through 7 should be repeated until the transducer is fully cali-brated.MANUAL OPERATION (select models)To manually control the transducer output, you will need to switch SW up for manual mode (see figure 6). Once in manual mode, you can increase or decrease the output by adjusting PB1 and PB2 (see figure 6).MAINTENANCEAfter final installation of the Series EPT-1 Electro-pneumatic Transducer, no routine maintenance is necessary. A periodic check of calibration is recommended following the procedure listed in the CALIBRATION section. Except for this, these transducers are not field serviceable and should be returned, freight prepaid, if repair is needed.Be sure to include a clear description of the problem plus any application information available. Contact customer service to receive a return goods authorization number before shipping.TRAN S DUCER 18-28 VAC TRAN S FORMER + HOT – NEUTRALCONTROLLER + OUTPUT– COMMON S HIELD/GROUNDLEGEND+ = S UPPLY VOLTAGE – = COMMON = INPUT+–TRAN S DUCER 18-28 VAC POWER S UPPLYCONTROLLER + OUTPUT– COMMON S HIELD/GROUNDLEGEND+ = S UPPLY VOLTAGE – = COMMON = INPUT+–+–MAINBRANCHZ S S W PB1PB2+========S UPPLY VOLTAGE COMMON INPUT ZERO S PANUP (MANUAL) DOWN (AUTO)INCREA S E DECREA S E+–Z S S W PB1PB2Figure 1: Wiring the electro-pneumatic transducer with a 24 VAC supply.Figure 2: Wiring the electro-pneumatic transducer with a 24 VDC supply.Figure 3: Jumper settings for electro-pneumatic transducers with 4-20mA input.Figure 4: Jumper settings for electro-pneumatic transducers with 0-5VDC input.Figure 5: Jumper settings for electro-pneumatic transducers with 0-10VDC input.Figure 6: Terminal locations on the electro-pneumatic transducer.。

ABP SERIESFor Use in Medical VentilatorsBasic Board Mount Pressure SensorsHigh Accuracy, Compensated/Amplified60 mbar to 1.6 bar | 1 psi to 15 psiDigital or Analog Output, Liquid Media CapableDESCRIPTIONThe ABP Series are piezoresistive siliconpressure sensors offering a ratiometricanalog or digital output for readingpressure over the specified full scalepressure span and temperature range.They are calibrated and temperaturecompensated for sensor offset,sensitivity, temperature effects andaccuracy errors (which include non-linearity, repeatability and hysteresis)using an on-board Application Specific Integrated Circuit (ASIC). Calibrated output values for pressure are updated at approximately 1 kHz for analog and2 kHz for digital. All products are designed and manufactured according to ISO 9001 standards.• Dry gases option: The input port is limited to non-corrosive, non-ionic media (e.g., dry air, gases) and should not be exposed to condensation. The gases are limited to media compatible with high temperature polyamide, silicone, alumina ceramic, silicon, gold, and glass.• Liquid media option: Includes an additional silicone-based gel coating to protect the electronics underport P1, which enables use withnon-corrosive liquids (e.g. water and saline) and in applications where condensation can occur. Since port P2 is designed for use with non-corrosive liquids, this option is often suitable for wet-wet differential sensing.

TOTAL ERROR BANDTotal Error Band (TEB) is a single specification that includes allpossible sources of error. TEB should not be confused with accuracy, which is actually a component of TEB. TEB is the worst error that the sensor could experience. The TEB specification on a datasheet may be confusing. Honeywell uses the TEB specification in its datasheet because it is the most comprehensive measurement of a sensor’s true accuracy. Honeywell also provides the accuracy specification in order to provide a common comparison with competitors’ literature that does not use the TEB specification. Many competitors do not use TEB—they simply specify the accuracy of their device. Theiraccuracy specification, however, may exclude certain parameters. On their datasheet, the errors are listed individually. When combined, the total error (or what would be TEB) can be significant.All Possible Errors2Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage) is achieved within the specified operating voltage.3The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure. 4Operating temperature range: The temperature range over which the sensor will produce an output proportional to pressure.5Compensated temperature range: The temperature range over which the sensor will produce an output proportional to pressure within the specified performance limits.6Temperature output option: Typical temperature output error over the compensated temperature range of 0°C to 50°C. Operation in Sleep Mode may affect temperature output error depending on duty cycle. 7Total Error Band: The maximum deviation from the ideal transfer function over the entire compensated temperature and pressure range. Includes all errors due to offset, full scale span, pressure non-linearity, pressure hysteresis, repeatability, thermal effect on offset, thermal effect on span, and thermal hysteresis.8Full Scale Span (FSS): The algebraic difference between the output signal measured at the maximum (Pmax.) and minimum (Pmin.) limits of the pressure range. (See Figure 2.)9Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the pressure range at25°C [77°F]. Includes all errors due to pressure non-linearity, pressure hysteresis, and non-repeatability.FIGURE 2. TRANSFER FUNCTION LIMITS 1Analog VersionsDigital Versions1Transfer Function “A” is shown.

第一节：了解LCD液晶显示屏一：字符型点阵式LCD液晶显示屏：LCD的应用很广泛，简单如手表上的液晶显示屏，仪表仪器上的液晶显示器或者是电脑笔记本上的液晶显示器，都使用了LCD。

在一般的办公设备上也很常见，如传真机，复印机，以及一些娱乐器材玩具等也常常见到LCD的足迹。

本站要介绍的LCD为字符型点阵式LCD模块（liquid Crystal Display Module)简称LCM，或者是字符型LCD。

字符型液晶显示模块是一类专门用于显示字母，数字，符号等的点阵式液晶显示模块。

在显示器件上的电极图型设计，它是由若干个5*7或5*11等点阵符位组成。

每一个点阵字符位都可以显示一个字符。

Various port configurations are available to measure absolute, gauge and differential pressures. Versions are offered with either analogue or digital outputs.This application guide should be read in conjunction with product data sheet 920-477.1.2Block DiagramApplication Guide1Pressure Sensor Type NPA1.3Analog CircuitsNote:Standard analogue versions of NPA are configured for ratiometric operation as shown in Figure2. For the circuits in Figures 3 and 4, a special version of the NPA with pin 10 (Vgate) activated should be used.Typical output load resistor R L (to V supply or Ground) = 10 kΩ (minimum 2.5 kΩ)Typical output load capacitance C L = 10 nF (maximum 15 nF)2Application GuidePressure Sensor Type NPA1.4Digital CircuitsThe circuits in Figures 2,3 & 4 on Page 2 can also be used for digital outputs with the following conditions:•The load resistor or capacitance is not required•No pull-down resistor is allowed•If a line resistor or pull-up resistor is used, the requirement for rise time (≤5 μs) must be met1.5Output ImpedanceThe source impedance defined by voltage drop due to load current is not specified as such for the NPA. The sensor incorporates a unity gain buffer at the output to control the output voltage within a range of load current / resistances. An error compensation circuit tracks and reduces the amplifier offset voltage to <1 mV.1.6Output Short ProtectionThe NPA does not incorporate short protection. A resistor R SP, as specified in Table1 below, should therefore be connected in series with the output.Table 1: Short Protection ResistorAmbient Temp. (°C)Resistor R SP (ohm)Up to 8551Up to 125100To minimize the effect on measurement accuracy caused by this resistance in analog mode, the load impedance R L should be chosen to ensure that R L>>R SP.Application Guide3Pressure Sensor Type NPA2.Pin ConnectionsTable 2: Pin ConnectionsPin No.Pin Name Pin Function1NC Not connected2NC Not connected3VP Sensor interface positive output4VSSP Sensor interface ground5NC Not connected6VSS Ground supply7NC Not connected8SIG Analog out, Digital out9VDD Supply voltage10Vgate Gate control for external JFET regulation/overvoltage protection11VN Sensor interface negative output12VDDP Sensor interface positive excitation13NC Not connected14NC Not connected4Application GuideApplication Guide 5Pressure Sensor Type NPA3.Digital Output3.1GeneralThe NPA sensor is available in 2 versions with digital output interface:•Pressure data only: NPA-600 series•Pressure & temperature data: NPA-601 seriesThe bit encoding is similar to Manchester in that clocking information is embedded into the signal (falling edges of the signal occur at regular periods). This allows the protocol to be largely insensitive to baud rate differences between the two ICs communicating. In user applications, the NPA sensor will be transmitting information and another IC in the system (typically a microcontroller) will read the data.3.2Bit EncodingData bits are transmitted as a Manchester duty-cycle encoded signal:Start bit 50% duty cycle used to set up strobe time Logic 175% duty cycle Logic 025% duty cycleStop BitHigh signal for half a bit widthThere is a half stop bit time between bytes in a packet.Figure 5: Manchester Duty CycleBit Window31.25 μs @ 32 kHz baud ratePressure Sensor Type NPA6Application Guide3.2 Bit Encoding (cont.)An oscilloscope trace of the data transmission demonstrates the bit encoding. Figure 6 below shows a single packet of value 96 hex (= 10010110 bin = 150 dec) being transmitted. Because 96Hex is already even parity, the parity bit P is set to 0.1 0 1 0 1 1 0 PSPressure Sensor Type NPA3.3Mode 1 - Pressure OnlyThe sensor first transmits the high byte of pressure data, followed by the low byte. The data resolution is 14-bits, so the upper two bits of the high byte are always zero padded. There is a half stop bit time between bytes in a packet. That means that, for the time of half a bit width, the signal level is high. Combining the high and low data bytes provides a 14-bit number corresponding to the pressure reading (see Figure7 below).Figure 7: Digital Output Bridge ReadingsThe actual pressure reading is dependent on the calibration set points for zero and full-scale pressure. This is illustrated in the following example, for a sensor that has been calibrated with the following parameters:•Excitation: 5 V olts•Full-scale Pressure: 10” H2O•Full-scale Pressure: set to 90% of rail•Zero Pressure: set to 10% of rail.In this example, the sensor would deliver the analog/digital outputs shown in Table4 below.Table 3: Analog/Digital Outputs for ExamplePressure (in.

The temperature byte represents an 8-bit value ranging from -50°C to +150°C.Figure 8: Digital Output Bridge Readings with TemperatureTable 4: Analog/Digital Outputs for ExampleT actual (°C)T O = 8-Bit Output Temperature-500-4013-3026-2038-1051064107720892596301024011550128601407015380166901791001911102041202171302301402421502553.5Data TransmissionData is transmitted in packets as shown in Figure 9 below.Figure 9: Transmission of data packets (NPA-600 pressure only mode)The total transmission time for both of digital output modes is shown in Table 5 below:3.6How to Read a Data PacketWhen the falling edge of the start bit occurs, measure the time until the rising edge of the start bit. This time (Tstrobe) is the strobe time. When the next falling edge occurs, wait for time period equal to Tstrobe, and then sample the signal. The data present on the signal at this time will be the bit being transmitted. Because every bit starts with a falling edge, the sampling window is reset with every bit transmission. This means errors will not accrue for bits downstream from the start bit, as it would with a protocol like RS232. It is recommended that when acquiring the start bit, the sampling rate should be at least 16x the nominal baud rate i.e. 16 x 32 kHz = 512 kHz.3.7How to Read a Data Packet Using a MicrocontrollerIt is best to connect the digital signal to a pin on the microcontroller that is capable of causing an interrupt on a falling edge. When the falling edge of the start bit occurs, it causes the microcontroller to branch to its ISR. The ISR enters a counting loop incrementing a memory location (Tstrobe) until it sees a rise on the digital signal. When Tstrobe has been acquired, the ISR can simply wait for the next nine falling edges (8-data, 1-parity). After each falling edge, it will wait for Tstrobe to expire and then sample the next bit.The digital line is driven by a strong CMOS push/pull driver. The parity bit is intended for error checking when the digital signal is driving long (>2m) interconnects to the microcontroller in a noisy environment. For systems in environments without noise interference, the user can choose to have the microcontroller ignore the parity bit.Table 5: Data Transmission TimesBaud Rate Bit Length IdleTime*Transmission Time (Pressure Only)Transmission Time (Pressure & Temperature)# BitsTotal Time(inc.

It is assumed that the NPA digital output is connected to the interrupt pin (PORTB,0) of the PIC and that the interrupt is configured for falling edge interruption.

The code also includes functionality to switch the sensor power to reduce consumption in battery-powered applications.It is assumed that the NPA digital output is connected to the PORT 0 (0x80hex) of the 8051 microcontroller. This code is for a microcontroller running at 24.5 MHz. However, frequencies from 8 to 24.5 MHz can also be used, in which case the number of nop (No Operation) commands in the wait routine should be adjusted accordingly.Hi#define PWR_PIN 0x40#define SIG_PIN 0x80#define PORT P2/******************************************************************************* FUNCTION MACROS******************************************************************************/#define NPA_INIT(){SFRPAGE = CONFIG_PAGE;PORT_CONFIG |= PWR_PIN;PORT &= ~PWR_PIN; /* power */\PORT_CONFIG &= ~SIG_PIN;PORT |= SIG_PIN; /* signal */}#define NPA_ON() SFRPAGE = CONFIG_PAGE; PORT |= PWR_PIN;#define NPA_OFF() SFRPAGE = CONFIG_PAGE; PORT &= ~PWR_PIN;#define NPA_SIGNAL() (PORT & SIG_PIN)/******************************************************************************* Blocking wait function* Assuming MCU runs at 24.5MHz, 1 nop = 1/(24.5MHz ÷ 8) µs = ~0.33µs* Number of nops for 15 µs = 15 ÷ 0.33 = 45******************************************************************************/#define WAIT_15_US()_nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_() _nop_();_nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_() _nop_();_nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_() _nop_();_nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_() _nop_();_nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_(); _nop_() _nop_();/****************************************************************************** * Function : getNPAPressure* Description : reads from the NPA its output value* Parameters : pointer for return value* Returns : read value******************************************************************************/ UINT16 getNPAPressure (UINT16 *Pressure_value16){UINT16 Pressure_value1 = 0;UINT16 Pressure_value2 = 0;UINT8 i;UINT16 Pressure;UINT8 parity;NPA_ON();sleep(200); // wait for stabilizationSFRPAGE = CONFIG_PAGE;while (NPA_SIGNAL()); // wait until start bit starts// wait, TStrobewhile (NPA_SIGNAL() == 0x00);// first data byte// read 8 data bits and 1 parity bitfor (i = 0; i < 9; i++){while (NPA_SIGNAL()); // wait for falling edgeWAIT_15_US();if (NPA_SIGNAL())Pressure_value1 |= 1 << (8-i); // get the bitelsewhile (NPA_SIGNAL() == 0x00); // wait until line comes high again}// second bytewhile (NPA_SIGNAL());// wait, TStrobewhile (NPA_SIGNAL() == 0x00);// read 8 data bits and 1 parity bitfor (i = 0; i < 9; i++){while (NPA_SIGNAL()); // wait for falling edgeWAIT_15_US();if (NPA_SIGNAL())Pressure_value2 |= 1 << (8-i); // get the bitelsewhile (NPA_SIGNAL() == 0x00); // wait until line comes high again}\NPA_OFF(); // switch NPA off// check parity for byte 1parity = 0;for (i = 0; i < 9; i++)if (Pressure_value1 & (1 << i))parity++;if (parity % 2)return FALSE;// check parity for byte 2parity = 0;for (i = 0; i < 9; i++)if (Pressure_value2 & (1 << i))parity++;if (parity % 2)return FALSE;Pressure_value1 >>= 1; // delete parity bitPressure_value2 >>= 1; // delete parity bitPressure = (Pressure_value1 << 8) | Pressure_value2;*Pressure_value16 = Pressure;return TRUE; // parity is OK}/******************************************************************************* Function : cmdGetNPA Value* Description : converts digital pressure value to pressure in real units* Parameters : none* Returns : none* Notes : none******************************************************************************/void cmdGetNPA Value (void){UINT16 Pressure_value;float Pressure_float;float pressure_min = -1.25; // pressure corresponding to output value 0 decfloat pressure_max = 11.25; // pressure corresponding to output value 16383 dec// values dependant on specific sensor rating// values shown are for sensor with full range of -1.25 to +11.25 inH2Oprintf("cmdGetNPA Value\n");NPA_INIT(); // init the I/O pins used for the NPANPA_OFF(); // switch the NPA off until useif (getNPAPressure(&Pressure_value)){Pressure_float = ((float)Pressure_value * (pressure_max - pressure_min) / 16383 + pressure_min; // conversion to real pressure unitsSFRPAGE_UART();printf("Pressure %u, %2.1f\n", Pressure_value, Pressure_float);}}4.Package Dimensions4.1Manifold FittingFigure 10: Package Dimensions (mm) - Manifold Fitting4.2Barbed FittingThe recommended tube size for the barbed fitting package shown in Figure11 below is:•3/32” I.D. x 7/32” O.D.

SENSORS FOR FOOD AND LIFE SCIENCES.TP - Series “Smart”Pressure TransmitterIntroductionThe Anderson-Negele “TP” series pressure transmitter is a microprocessor-based sensor specifically designed for sanitary fluid process applications in the Life Sciences industry. This product provides an extremely high level of performance combined with the flexibility of digital communication via the “HART” protocol. The “TP” series can be specified in several configurations including high temperature models that are available in direct or remote mount variations. The high temperature direct mount is also recommended for applications where a horizontal orientation is re-quired for display viewing, such as tank tops and overhead lines. All models comply with UL, “intrinsically safe” requirements for Class 1, Div. 1, Groups A-D. The units may be ordered with any of our wide variety of sanitary process fittings.The “TP” series simultaneously outputs an analog 4-20 mA signal while communicating digitally with a hand-held communicator or other “HART” host device. This allows configuration of parameters such as range, engineering units, tagging info, and other device specific information, from any accessible point inthe output loop. The analog output can even be “trimmed” or calibrated while online, if required. Also retained are internal, non-interactive zero and span analog adjustments. This provides the user with the immediate performance enhancements of this new product, with future compatibility with the “HART” protocol.As with all Anderson-Negele sensors, the “TP” series is designed to be cleaned and steam sterilized in place. The optional LCD display can be factory scaled to linearprocess engineering units, mA output, or 0-100%.2ANDERSON INSTRUMENT COMPANY 156 Auriesville Road Fultonville, NY 12072Phone 800-833-0081Fax 518-922-8997************************Tech.

MCU12单片机压力传感器模块使用说明一、线路及各端口1、线路图可参阅模块丝印实际线路。

2、±12V电源端分别接±12V电源。

3．输出端为压力传感器通过放大器放大的实际电压值。

4、输入端是报警电路的控制端。

二、使用说明（以实际电子秤为例）1、压力传感器空载时输出电压为V零。

本模块设定为0.1V以下。

2、压力传感器满载时（200g=10砝码），输出电压为V满，本模块设定为4.5V至5V之间。

3、有效输出电压V有效，等V满减去V零。

例：V零为0.1V，V满在200g时为4.6V，那么 V有效=4.6V-0.1V=4.5V4、根据上述已知满载时V有效电压为4.5V，那么每克输出电压也就知道了。

V每克=4.5V÷200g=0.0225V/g5、现将一个未知重量物体置于秤上已知输出电压Vx为3.6V，求X物体重量为多少?X(g)=3.60.1155.55 0.0225/0.0225/Vx V V Vg V g V g--=≈零6、单片机与压力传感器模块连接如图所示：通过A/D转换读入V零，V满进行校准求出V每克，然后读出 Vx电压值就可求出X物体重量了，并以XXX.XX克显示在单片机显示屏上。

7、本模块设定了一个报警电路OV 低电平关，5V（高电平）报警，它的输入端与单片机输出端口连接，当电子秤称重超过200g可报警。

设定值可自己设定。
