Product Details
EJA438E Diaphragm Sealed Pressure TransmitterIntroduction:
EJA438E Diaphragm Sealed Pressure TransmitterAdopting monocrystalline silicon resonant sensor technology, it is suitable for measuring the flow rate, liquid level, density, and pressure of liquids, gases, or vapors. EJA438E converts measured differential pressure into 4-20mA DC current signal output, which can measure, display or remotely monitor static pressure. It has functions such as fast response, remote setting, and self diagnosis.
The EJA-E series products offer BRAIN, HART/HART (1-5VDC) low-power models, FF fieldbus, and PROFIBUS PA communication protocols, with standard configurations certified with SIL 2 safety
