Yokogawa EJA438E Diaphragm Sealed Pressure Transmitter

The EJA438E diaphragm sealed pressure transmitter adopts single crystal silicon resonant sensor technology, which is suitable for measuring the pressure and liquid level of high and low temperature, high vacuum, high viscosity, and easily crystallized media. It has functions such as fast response, remote setting, and self diagnosis.

The Yokogawa instrument diaphragm sealed transmitter meets various needs and applications by combining the pressure measuring flange with the transmitter body. It can measure liquid level, density, pressure, as well as the flow rates of liquids, gases, and vapors. It is also suitable for situations where the measured medium cannot be introduced into the pressure part of the transmitter. And through precise design and manufacturing, interference caused by the physical properties of the sealed liquid and environmental temperature is reduced, providing accurate, stable, and reliable measurements.

The functional features of EJA438E include:

Accuracy ± 0.2%

Response time of 200 milliseconds

TUV and Exida SIL2/SIL3 certification

Characterization of 10 signal curves

Proactively compensate for the density of capillary filling fluid

Provide communication protocols such as HART 5/7, HART (1-5V DC) low-power type, FF fieldbus, PROFIBUS PA, and BRAN.
