Yokogawa EJA440A High Pressure Transmitter 4 to 20 mA DC with digital communication HART protocol
The high performance differential pressure transmitter model EJA430A can be used to measure liquid, gas, or steam flow as well as liquid level, density and pressure. It outputs a 4 to 20 mA DC signal corresponding
to the measured differential pressure. Model EJA430A also features remote setup and monitoring through communications with the BRAIN™ terminal and CENTUM CS™ or XL™ or HART® 275 host.
