Yokogawa EJA430A-EAS4B-92EA/D3/KU2 Gauge Pressure Transmitter

Yokogawa EJA430A-EAS4B-92EA/D3/KU2 Gauge Pressure Transmitter.

The high performance gauge pressure transmitter model EJA430A can be used to measure liquid, gas, or steam pressure. It outputs a 4 to 20 mA DC signal corresponding to the measured gauge pressure. Model EJA430A also features remote setup and monitoring through communications with the BRAIN™ terminal and CENTUM CS™ or μXL™ or HART® 275 host.
