热电偶热电阻检定装置技术报告范文英文回答：Title: Technical Report on Thermocouple and Resistance Thermometer Calibration Equipment.Introduction:In this technical report, I will discuss thecalibration equipment used for thermocouples and resistance thermometers. Calibration is essential to ensure accurate temperature measurements in various industries, including manufacturing, energy, and scientific research. The calibration process involves comparing the readings of the temperature sensors with known reference values and making necessary adjustments to ensure accuracy.Equipment Description:The calibration equipment for thermocouples andresistance thermometers typically consists of a temperature control unit, a reference temperature sensor, and a data acquisition system. The temperature control unit provides a stable and precise temperature environment for the calibration process. The reference temperature sensor is a highly accurate sensor with a known temperature value, used to compare and verify the readings of the sensors being calibrated. The data acquisition system records the readings from both the reference sensor and the sensors under calibration for analysis and adjustment.Calibration Procedure:The calibration procedure involves several steps. Firstly, the temperature control unit is set to a specific temperature, which is within the range of the sensors being calibrated. The reference temperature sensor is then placed in the controlled environment, and its reading is recorded. Next, the sensors under calibration are placed alongside the reference sensor, and their readings are also recorded. Any discrepancies between the readings of the sensors under calibration and the reference sensor are noted. Finally,adjustments are made to the sensors under calibration to align their readings with the reference sensor.Example:To illustrate the calibration process, let's consider a scenario where we need to calibrate a thermocouple used in a furnace. We set the temperature control unit to 1000 degrees Celsius, which is within the operating range of the thermocouple. The reference temperature sensor, a platinum res istance thermometer with a known accuracy of ±0.1 degrees Celsius, is placed in the furnace. Its reading is recorded as 1000.2 degrees Celsius. The thermocouple being calibrated is placed alongside the reference sensor, andits initial reading is recorded as 1000.5 degrees Celsius. Based on the discrepancy of 0.3 degrees Celsius, adjustments are made to the thermocouple to align its reading with the reference sensor. This calibration process ensures that the thermocouple provides accurate temperature measurements in the furnace.中文回答：标题，热电偶和热电阻检定装置技术报告。

工作用廉金属热电偶的使用及其校准刘锰天津市检测技术研究所内容摘要：本文通过对热电偶测温原理、误差来源及消除方法的介绍，使我们对热电偶进行温度测量时应该注意的问题及解决的方法有了系统的掌握，并对工作用廉金属热电偶的校准以及不确定度的报告与表示，给予了明确的论述。

关键词：工作用廉金属热电偶、校准、不确定度前言：1821年，德国物理学家塞贝克发现，在两种不同的金属所组成的闭合回路中，当两接触处的温度不同时，回路中会产生一个电势，这就是热电效应，也称作“塞贝克效应”。

塞贝克效应发现之后，人们就为它找到了应用场所。

利用塞贝克效应，可制成温差电偶（thermocouple ，即热电偶）来测量温度。

只要选用适当的金属作热电偶材料，就可轻易测量到从-180℃到+2000℃℃的温度，如此宽泛围的测量范围，令酒精或水银温度计望尘莫及。

现在，通过采用一些特殊材质制做的热电偶温度计，甚至可以测量高达+2800℃的温度。

因此热电偶成为工业上最常用的温度检测元件之一。

一、热电偶测温基本原理将两种不同材料的导体或半导体A 和B 连接起来，构成一个闭合回路，这就构成了热电偶。

如图1所示，温度t 端是感温端称为测量端, 温度t 0端是连接仪表端称为参考端或冷端,当导体A 和B 的两个点t 和t 0之间存在温差时,就在回路中产生电动势E AB (t,t 0), 因而在回路中形成电流,这种现象称为“热电效应”。

这个电动势称为热电势,热电偶就是利用这一效应来工作的。

热电势的大小与t 和t 0之差的大小有关，当热电偶的两个热电极材料已知时,由热电偶回路热电势的分布理论得知热电偶两端的热电势差可以用下式表示()()()00,t E t E t t E AB AB AB -=式中：()0,t t E AB －热电偶的热电势； ()t E AB －温度为t 时工作端的热电势； ()0t E AB －温度为t 0时冷端的热电势。

从上式可看出，当工作端的被测介质温度发生变化时，热电势随之发生变化，因此，只要测出()0,t t E AB 和知道()0t E AB 就可得到()t E AB ，将热电势送入显示仪表进行指示或记录，或送入微机进行处理，即可获得测量端温度t 值。
