摘要

一种用于工业应用的红外温度传感器已经开发出来,重点是在提供经济解决方案的同时实现所需的性能。该传感器以热电堆探测器为基础,辅以专门设计的封装,即使在高压发电机断路器遇到的恶劣环境条件下也能保持性能。对传感器的热布局进行了模拟,以优化封装。通过实验验证了传感器的性能:对几个传感器进行了从室温到120℃的物体温度测试,线性误差小于3℃。在-5°C和60°C之间的实际环境温度循环中保持精度。并进行了电磁干扰和振动试验。

Infrared temperature sensor for industrial application: Package design for reliable operation in a high voltage generator circuit breaker
An IR temperature sensor for industrial applications has been developed with the focus on achieving the required performance while providing an economical solution. The sensor is based on a thermopile detector supplemented by a specifically designed package to maintain the performance even under harsh environmental conditions encountered in a high voltage generator circuit breaker. Simulations of the thermal layout of the sensor have been performed to optimize the package. The performance of the sensor has been validated by experiments: Several sensors were tested for object temperature from room temperature to 120 °C with a linearity error of less than 3 °C. The accuracy was maintained under realistic ambient temperature cycles between -5 °C and 60 °C. Furthermore EMI and vibration tests have been performed.
