产品介绍

Description

ECA210AECA220A法兰安装式差压变送器用于测量液体、气体和蒸汽压力,并将其然后转变成420mADC的电流信号输出。

The ECA210A and ECA220 flange mounting differential pressure transmitter is used to measure the pressure of liquid, gas and steam, and then converted into a 4-20mADC current signal output.
ECA210A
ECA220也可与HART275手操器互通讯,通过它们进行设定、监控等。

ECA210A and ECA220 can also communicate with HART275 data setter, to having setting and monitoring and so on.
