摘　　要：本文介绍一种新研制的电位计式罗盘,它具有体积小、功耗低、重量轻、价格便宜等特点。由于它不是采用滑动式接触,因而除了轴承和轴尖之外没有其他摩擦误差。一般情况下磁铁可自由活动,在地磁场中则恒指南北。当驱动线圈加上取样电压时,电位计与导电环接通,输出端即输出一个与地磁场方位角相对应的电压值。此种罗盘可用于各种海流计上作为测向传感器,也可用于其他需测方位角的仪器上。本文介绍其工作原理,结构,并对准确度进行分析。A potentiometer compass designed with low power consumption, light weight,and inexpensive is described in this paper.There is no frictional error except that of bearing and pivot because it does not use sliding contact.tGenerally the magnet can turn freely on it's pivot and set itself to point North and South.At the moment when the co- mpass is driven by a direct current the potentiometer and the conduc- ting ring are contacted while in the output end there will be an outp- ut voltage,which varies corresponding to the earth's magnetic field angle.Being used as a current direction sensor,this compass is suitable for all kinds of current meters required by measuring direction. This paper introduces the operating principle,construction of the compass.
