Abstract

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.
工业用红外温度传感器:高压发电机断路器可靠运行的封装设计
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。
