1、 Product Description:

Sealed diaphragms are used to prevent process media from directly entering the pressure sensor components of differential pressure transmitters. They are connected to the transmitter through capillary tubes filled with fluid. The EJA438W/EJA438N diaphragm sealed pressure transmitter can be used to measure the flow rate, liquid level, density, and pressure of liquids, gases, or vapors, and then convert them into 4-20mA DC current signals for output. The EJA series supports BRAN, HART, and FOUNDATION™ Fieldbus or PROFIBUS PA communication protocol.
