Yokogawa EJA 438 E
Highlights
Description
The E J A438 E Diaphragm Sealed Gauge Pressure Transmitters are capable of measuring the pressure of liquids, gases, or steam. The E J A438 E generates a 4 to 20 m A D C signal that corresponds to the measured pressure. It additionally has rapid response, remote configuration and monitoring by B R A I N or H A R T connectivity, as well as self-diagnostic capabilities. B A S E Fieldbus, P R O F I B U S P A, and 1 to 5 V D C with H A R T ( Low Power) protocol types are also offered. The E J A- E series devices, in their normal configuration—excluding the Fieldbus, P R O F I B U S, and Low Power variants—are certified to meet S I L 2 safety requirements.
