摘　　要：针对数字式皮革收缩温度测定仪中霍尔位移传感器组件自身的非线性特性而造成的测量误差,选用高分辨率及线性度好的直线型容栅传感器,提高测量精度。对容栅传感器设计了机械工装、硬件电路及软件程序,并进行试验测试,结果表明采用容栅传感器的位移测量效果明显优于霍尔传感器。The measurement errors were mainly caused by nonlinear characteristics of Hall displacement sensor component in digital leather shrinkage temperature measuring instrument. Thus high resolution and good linearity of linear capacitive sensor were chose to improve the measurement accuracy. The capacitive sensor was designed with mechanical fixture, hardware circuit and software program, and then it was used in experimental testing. The results show that the measurement effectiveness of capacitive displacement sensor is better than that of the Hall sensor.
