1、product brief introduction
Seal diaphragm is a pressure sensor component that used to prevent process medium directly into the differential pressure transmitter,they are connected with the transmitter through filled with fluid in the capillary. EJX118W, EJX118W type diaphragm sealed differential pressure transmitter used to measure liquid, gas or steam flow and liquid level, density and pressure, and then transform it into 4 ~ 20 mA DC signal output. EJA pressure transmitter series support BRAIN, HART and FOUNDATION fieldbus PROFIBUS PA or communication protocol.
