本文介绍一种可用于１３Ｋ－７００Ｋ温度范围内，并可线性移动的非接触微位移、振动测量用电容式传感器，该传感器与一种全新的测量电路──等电位蔽感应分压器电桥测量电路相结合可用于固体内耗及弹性模数的测量以及对精密轴承、电机转子晃动等的测试。
This article describes a non-contact, micro-displacement, vibration-measuring, capacitive sensor that can be used in the temperature range of 13K to 700K and moves linearly. The sensor is connected to a new measurement circuit, The combination of measurement circuits can be used for the measurement of solid internal friction and elastic modulus as well as the testing of precision bearings, motor rotor sloshing and the like.
