Yokogawa EJA310A Absolute Pressure Transmitter 4 to 20 mA DC with digital communication HART protocol
The high performance differential pressure transmitter model EJA310A 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 EJA310A also features remote setup and monitoring through communications with the BRAIN™ terminal and CENTUM CS™ or XL™ or HART® 275 host.
