摘要
所介绍的变送器采用固体集成电路，是一种非接触式、量程和零点可调的二线制开环式仪表。它基于差动电容的原理，将转角或直线位移转换成标准的电流信号，用以检测各种阀门开度和位移变量。经在电厂长期运行考核，其性能稳定，维护工作量小，表明具有广泛的应用前景。
The transmitter introduced here is made of solid IC, which is a kind of two wire open loop instrument featuring with non contact and range/zero point adjustable. Based on the differential electric capacity principle, it transmits the angular or linear displacement into standard electric current signals to measure the opening and displacement variables of diverse valves. It has been proven by a long term operation in power plant that the transmitter has a stable performance and needs little maintenance, and will be widely applied in near future.
