电阻远传压力表

Pressure gauge with resistance transmitter
仪表由一个弹簧管压力表和一个滑线电阻式传感器组成，当被测压力变化时，弹簧管端产生位移，一方面通过传动系统使指针在度盘上指示相应压力，另一方面带动电刷在电阻上滑行，使被测压力值的变化转换为电阻值的变化，并传至二次仪表上指示相应的压力。

The gauge is formed by a bourdon tube pressure gauge and a adjustable resistance transmitter. When the pressure is changing, the tube end deformed, and the pointer is to show the pressure value through the driving system, at the same time, the brush is slipping on the resistance to transmit the pressure values to resistant values, which is transmited to the secondary gauge to show the relative pressure value.
