热电偶是工业生产中运用相当广泛的温度传感器,然而在使用的过程中,经常需要周期性的检定和修正,以确保热电偶温度计测温的准确性。本文设计了一款新型的热电偶检定系统,该检定系统分为测量、控制和上位机三大模块。实验结果表明,此检定系统提高了检定效率,将检定过程中所能出现的误差降低至最低。 Thermocouples are widely used in industrial production temperature sensor, however, in the process of using, often require periodic verification and correction to ensure the accuracy of thermocouple thermometer temperature. This article designed a new type of thermocouple test system, the test system is divided into measurement, control and host computer three modules. The experimental results show that the verification system improves the verification efficiency and minimizes the error that can occur in the verification process.
