K型热电偶热端封装响应延迟解决方案

K Type Thermocouple Hot Side Packaging Response Latency Solutions

K型热电偶温度传感器在工业航空领域应用广泛。K型热电偶温度传感器的热端直接裸露在被测环境内极易受到外界环境的影响,所以,热电偶的热端也需要封装。但是封装后的K型热电偶的响应时间延迟。该文详细阐述了K型热电偶热端暴露在被测环境内会受到的外界影响从而引起输出误差,封装避免外界影响及可实施方案。

K-type thermocouple temperature sensors are widely used in the field of industrial aviation. The hot end of the K--type thermocouple temperature sensor is directly exposed in the measured environment vulnerable to the influence of the external environment,and therefore,the thermocouple hot side also needs to be encapsulated. But the package after the K--type thermocouple response time delay.This paper elaborates a K--type thermocouple hot end will be exposed in the measured environment outside influence causing output error package to avoid outside influence, and the implementation of the program.
