Hydac电子流量变送器3100
Electronic Flow Rate Transmitter EVS 3100 for Oils / Viscous Fluids
Description:
描述:
The flow rate transmitters in the series EVS 3100 (aluminium range) are specially designed for use in hydraulic and other fluid technology systems.
流量变送器中系列EVS3100(铝系列)是专门设计用于在液压等流体技术系统。
They operate according to the turbine principle, i.e. the speed of an impeller turning in the fluid flow is measured
and converted into a 4 .. 20 mA analogue signal.
他们根据涡轮操作叶轮的原理,即,速度转弯中的流体流被测量并转换成4.. 20 mA的模拟信号。
Two further G1/4 threaded holes in the turbine housing provide connections for additional units, e.g. temperature and pressure transmitters.
另外两个G1/4螺纹孔在涡轮壳体提供更多的单位连接,例如的温度和压力发射器。
