摘要
介绍了TO-8型压力传感器的性能及电源电路.以气体导热系数测定实验为例,用TO-8型压力传感器制成的测压装置代替旋转式麦氏真空计,利用可调针孔式放气阀对真空气压进行连续调节,实现了对测试系统真空度的实时监测.
The performance and the power supply circuit of TO-8 pressure sensor are introduced. In the experiment of measuring coefficient of thermal conductivity of air, apparatus using TO-8 pressure sensor is substituted for rolling McLeod vacuum gauge, the vacuum pressure could be adjusted continuously by using the pinhole valve and the vacuum degree of the system could be monitored realtimely.
