Yokogawa EJA438E Diaphragm Sealed Gauge Pressure Transmitter

EJA438E diaphragm sealed pressure transmitter adopts monocrystal silicon resonant sensor technology, which is suitable for measuring the pressure and liquid level of high and low temperature, high vacuum, high viscosity and easy crystallizing medium. It has the functions of quick response, remote setting and self-diagnosis.

Product Details

Yokogawa EJA438E Diaphragm Sealed Gauge Pressure Transmitter

Diaphragm sealed transmitter can meet various demands and applications through the combination of pressure measuring flange and transmitter body. It can measure liquid level, density, pressure and flow rate of liquid, gas and steam. It is also suitable for the case that the measured medium cannot be introduced into the pressure part of transmitter.And through the precise design and manufacture, reduce the interference caused by the physical characteristics of the sealed liquid and the ambient temperature, and provide accurate, stable and reliable measurement.
