Pt100探头原理解释及接线说明（图文）
Pt100探头原理解释及接线说明（图⽂）Pt100温度传感器接线说明Pt100就是说它的阻值在 0度时为100 欧姆，PT100 温度传感器。
是⼀种以铂(Pt)作成的电阻式温度传感器，属于正电阻系数,其电阻和温度变化的关系式如下：R=Ro(1+αT)Pt100温度传感器的主要技术参数如下：测量范围： -200℃～+850℃；允许偏差值△℃： A 级± （0.15＋0.002│t│）， B 级±（0.30＋0.005│t│）；热响应时间<30s；最⼩置⼊深度：热电阻的最⼩置⼊深度≥200mm；允通电流≤5ma。
另外，pt100="">PT100 温度传感器三根芯线的接法：PT100铂电阻传感器有三条引线,可⽤ A、B、C（或⿊、红、黄）来代表三根线,三根线之间有如下规律：A 与 B 或 C之间的阻值常温下在 110 欧左右,B 与 C 之间为 0欧,B 与 C 在内部是直通的,原则上 B 与 C 没什么区别。
仪表上接传感器的固定端⼦有三个：A 线接在仪表上接传感器的⼀个固定的端⼦.B 和C 接在仪表上的另外两个固定端⼦，B 和 C 线的位置可以互换,但都得接上。
如果中间接有加长线,三条导线的规格和长度要相同。
热电阻的 3 线和 4 线接法：是采⽤ 2 线、3 线、4 线，主要由使（选）⽤的⼆次仪表来决定。
⼀般显⽰仪表提供三线接法，PT100 ⼀端出⼀颗线，另⼀端出两颗线，都接仪表，仪表内部通过桥抵消导线电阻。
⼀般 PLC 为四线，每端出两颗线，两颗接 PLC 输出恒流源，PLC 通过另两颗测量 PT100上的电压，也是为了抵消导线电阻，四线精确度最⾼，三线也可以，两线最低，具体⽤法要考虑精度要求和成本。
PT100温度传感器产品特征：1、不锈钢套管封装，经久耐⽤；2、活动螺丝固定，使⽤⽅便；3、按照国际IEC751 国际标准制造，即插即⽤；4、多种探头尺⼨可选、适应⾯⼴；5、⾼精度、⾼稳定、⾼灵敏；6、外形⼩巧，经济实⽤。
LABCAL-PRO Pt100 和热敏电阻传感器精密温度计 记录器说明书
LABCAL-PROThe Labcal PRO is a third generation instrument developed over a 25 year period from the very successful Labcal Plus thermometer. Like its predecessors, the Labcal PRO provides laboratory standard temperature measurement and many user features but provides higher accuracy, higher resolution and greater versatility to extend the scope of applications.The Labcal PRO is fully characterised for Pt100 sensors and all major thermocouples J,K,N,T,E,R,S and B. Exceptionally stable automatic cold junction compensation with a rejection of 100:1 is incorporated for thermocouple ranges. Alternatively, external or manual referencing can be selected as required.Displayed values and user information are indicated on a bright clear OLED screen with diffused backlighting. Data can be displayed in °C,°F,K,Ωor mV as required; nine front panel push keys, the only user controls, are used in conjunction with the display screen. It is this arrangement which makes for very simple and “friendly” operation.Resolution is a user selectable 0.001 or 0.01°C for Pt100 sensors and 0.1°C for thermocouples. All computations are performed digitally without drift. Overall stability is optimised by utilising only the highest quality components including high precision, expensive metal film resistor networks.There are four input ports, two for thermocouples and two for 3 or 4 wire Pt100 sensors; the instrument automatically recognises 3 or 4 wire configurations.The Labcal PRO can accept two Pt100 sensors and/or two thermocouples of similar or different types (J,K,N,T,E,R,S and B). The measured temperature can be displayed directly from one of the inputs or differentially between similar or different inputs. Differential temperature and the two individual channel temperatures are displayed simultaneously.Individual calibrated sensors can have their appropriate calibration values programmed into the Labcal PRO using either the keypad or the PC software supplied. The PC software also allows corrections in the form of constants for individual Pt100 sensors to be programmed in. The non-volatile memory ensures that the values are retained (until such time as they are changed) even after switch-off. Where the calibration certificate relating to a particular probe states specific Ωor mV values at stated temperatures, up to ten such values are entered into the Labcal PRO with their relevant temperature points using the front panel keypad or the software. The instrument then digitally self-calibrates to the associated probe over the range embraced in the calibrated values used; the temperature readout is “corrected” accordingly. Additional manual procedures are not required to compute precise temperature readings since these are displayed directly; miscalculation errors are thus eliminated. Very high system accuracies, better than 25 milliKelvins can be achieved using probe matching.Corrections which are “programmed in” can be displayed for confirmation. However, initial input, adjustment, enabling and disabling of corrections are protected by a special key sequence to preventaccidental or unauthorised changes. Values can be changed by an authorised user at any time.For Pt100 inputs, SMART probes can be used which incorporate dedicated ‘correction values‘ within the connector of each probe.When a SMART probe is connected to input A or B or both inputs,the corrections are automatically applied without the need for user intervention.A common application for the Labcal PRO is the comparison calibration of “working” sensors against a calibrated reference standard or semi-standard sensor. For example, the sensor under test in channelB is compared against the reference sensor (with programmed corrections) in channel A. When applied, the null function corrects the differential temperature readout between two sensors to zero. For example, the apparent temperature difference between two sensors known to be at the same actual temperature can be corrected to zero prior to, for example, heat exchanger experiments.All four inputs can be scanned and values logged according to parameters set up by the user in the PC software;the instrument incorporates a real-time clock and on-board memory.The adjustable contrast OLED display screen provides data readout, user prompts and mode annunciation. This very important feature ensures a high degree of user friendliness and confidence. User prompts indicate which buttons to press in the appropriate sequence when selecting parameters and functions and when setting calibration values. Mode annunciation indicates which mode of operation is currently selected.A flash drive USB port is provided to allow data to be stored and/or exported. Firmware update are also facilitated via this port.PC software running in WINDOWS is provided as standard; it allows programming of custom calibration, remote control & measure and logging functions.SPECIFICATIONSAll values are valid for a nominal 240V 50Hz instrument supply and 20ºC ambient temperature(±2ºC)GeneralInputs/Ranges/SensorsType Pt100 to IEC 751 (ITS 90 refers).-200ºC to +850ºCRo = 100Ω3 or4 wire connection with automatic recognition(with manual override)Thermocouples to IEC 584No isolation exists between inputs.Type Type S -50 to 1768ºCType R -42 to 1766ºC Noble MetalType B +254 to 1818ºCType J -200 to 1200ºCType K -195 to 1370ºCType E -190 to 995ºC Base MetalType N -160 to 1300ºCType T -193 to 399ºCOverall Pt100Accuracy±0.01ºC ±0.0005% of spanThermocouplesi) Base Metal ii) Noble Metal±0.2ºC from -50ºC to 700ºC±0.3ºC from 850ºC tofull scale±0.4ºC from -200ºC to -50ºC±0.4ºC below 850ºC±0.4ºC from 700ºC to ±0.7ºC below 0ºCfull scaleNote:Type B not characterized below +200ºC Linearisation ConformityPt100Better than ±0.01ºCThermocouples±0.05ºC base metal (-200ºC to span)±0.1ºC noble metal above 200ºCNote: Performance of ADC (0.5µV resolution ) is superior to published thermocouple table best resolution of 1µV.Stability (vs ambient temperature)Pt100Better than 0.0025ºC per 1ºC ambient changeThermocouplesZero: negligible drift excluding CJC effectScale: < ±0.1ºC in 15ºCWarm-up Negligible under normal ambient conditions.

pt100使用简介
PT100三线制测量电路引言PT100 是一种广泛应用的测温元件,在-50℃~600℃范围内具有其他任何温度传感器无可比拟的优势,包括高精度、稳定性好、抗干扰能力强等。
由于铂热电阻的电阻值与温度成非线性关系,所以本模块需要进行非线性校正,一般的模块采用模拟电路校正,这种校正的精度不高,而且温漂等受干扰的程度也比较大。
本模块采用了软件查表插值的方法进行校正,最后转换成III型信号。
III型信号是当被测信号从下量程到上量程(0%~100%)变化时,输出线上对应4－20mA 电流的变化。
此外模块还具有MODBUS协议的通讯端口,可以直接和任何MODBUS口连接。
系统设计整个模块基于AVR新型的Atmega16单片机,采用三线制形式,这样可以去除导线电阻带来的零点不准确,经过差分放大电路直接得到0~5V的信号电压,这样就可以直接输入到A/D转换器。
数据处理部分,将PT100分度表中的每隔10℃的电阻值写入到闪存中,这样,将得到页脚内容1电压值回算到电阻值,这样进行查表,当电阻位于某一段之间时,再进行线性处理,这样系统的线性化程度比较高可以达到0.2%。
D/A转换系统采用373芯片作为锁存器,采用权电阻网络进行D/A转换,这样可以节省成本,而且精度也可以得到保证。
最后再经过一个电压电流转换部分,把信号以III型信号传送出去,完成模块的功能。
图1 采样电路采样电路采样电路如图1所示,PT100以三线制接到J0,这样连接PT100的两侧的导线长度相等,而且分别加在两侧的桥臂上,这样导线电阻得以消除,当 PT100输出100Ω时可以调节R1的阻值,以调整温度下限,当温度范围是0~300℃时,电桥电压经过放大后,Anolog0的电压正好是0~5V, 这样可以完整使用单片机的A/D转换器的转换精度。
页脚内容2图2 主机电路主机电路如图2。
CPU采用Atmega16 ,它自带8路10位A/D转换器,转换速度快,精度高,而且不需要外扩任何器件。

pt100铂电阻说明书【PT100铂电阻说明书】一、产品概述PT100铂电阻是一种温度传感器，广泛应用于各种工业领域中对温度进行测量的需求。
本说明书将为您介绍PT100铂电阻的基本原理、技术参数、使用方法以及注意事项。
二、基本原理PT100铂电阻的温度测量原理是通过铂电阻的电阻值随温度变化而产生的线性关系，实现温度的测量。
随着温度的升高，铂电阻的电阻值也会相应增加，反之亦然。
PT100铂电阻的可靠性和准确性使其成为工业温度测量的首选传感器之一。
三、技术参数1. 电阻值：PT100铂电阻的电阻值为100欧姆，在温度为0℃时，其电阻值为100欧姆。
2. 温度范围：PT100铂电阻的测量温度范围通常为-200℃至600℃，但实际可根据具体需求定制。
3. 线性关系：PT100铂电阻的电阻值与温度呈线性关系。
在标准条件下，每摄氏度的温度变化约对应0.385欧姆的电阻变化。
四、使用方法1. 连接方式：将PT100铂电阻的两端与测量仪器进行连接，确保接触良好并固定牢固。
2. 温度校准：在使用前，建议进行温度校准以确保测量结果的准确性。
使用专用温度校准设备，按照说明进行校准操作。
3. 安装位置：根据具体需求选择合适的安装位置，避免暴露在过高温度或腐蚀性介质中，以免影响传感器的正常使用寿命。
4. 保养维护：定期检查PT100铂电阻的连接状态和电阻值变化，如有异常及时处理或更换。
五、注意事项1. 使用环境：避免将PT100铂电阻使用于超出其额定温度范围的环境中，以免损坏传感器或影响测量准确性。
2. 防护措施：根据实际需求，采取相应的防护措施，如加装防护套管、防水罩等，以延长PT100铂电阻的使用寿命。
3. 注意连接性：在连接过程中，应确保PT100铂电阻与测量仪器的连接稳定可靠，避免接触不良或短路等情况。
4. 避免冲击：PT100铂电阻属于精密仪器，在使用过程中需避免剧烈振动或外部冲击，以免影响其性能。
5. 专业维修：如遇到无法解决的故障或损坏情况，请联系专业技术人员进行维修或更换。

M5 为保持参数。定义为输出值变化 5％时，控制对象基本稳定后测量值与变化前测量值的差 值。同一系统的 M5 参数一般会随测量值有所变化，所以应取工作点附近为准。M5 参数值主要决 定调节算法中积分作用，和 PID 调节的积分时间类似。M5 值越小，系统积分作用越强。M5 值越 大，积分作用越弱。
