研究了用通用集成运算放大器和正电压可调集成三端稳压器实现电位器式位移传感器负载特性非线性自动补偿的方法。该方法既较好地补偿了电位器式位移传感器负载特性的非线性,又很好地解决了电位器式位移传感器负载能力弱的问题。测试表明:该方法补偿效果好,具有实用性。

?In order to automatically compensate the load characteristic of potentiometric displacement sensor,a method based on a general purpose integrated operational amplifier and a integrated voltage regulator is studied.The method not only can compensate the nonlinearity of the load characteristic of the sensor perfectly,but also can increase the load carrying capacity of the sensor greatly.It is proved by testing results that the method has good compensating effectiveness.
