一.人造卫星温度遥测人造地球卫星是空间科学研究和通信等的重要工具。为了使卫星正常工作,必须控制和监测卫星内部的温度。在卫星内部,温度一般都不超过200℃,所以,全部采用接触测温技术。对于卫星上用的测温元件,除了要求精确可靠之外,还要求体积小,重量轻,灵敏度高,输出信号大等等。根据一些资料得知,卫星上温度遥测用得最多的是热敏电阻温度计,其次是
I. Artificial satellite temperature telemetry The artificial earth satellite is an important tool in space science research and communications. In order for the satellite to work properly, the temperature inside the satellite must be controlled and monitored. Inside the satellite, the temperature is generally not more than 200 ℃, therefore, all using contact temperature measurement technology. For satellite temperature components, in addition to accurate and reliable, but also requires small size, light weight, high sensitivity, the output signal and so on. According to some sources, the most commonly used temperature telemetry on the satellite is the thermistor thermometer, followed by
