High Static Differential Pressure Transmitter (brain protocol )
Name: Eja120a brain protocol pressure transmitters
Model: Eja120a
Description of Eja120a brain protocol pressure transmitters:
The high performance of Eja120a brain protocol pressure transmitters outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure.
Model EJA120A also features remote setup and monitoring through communications with the BRAIN™ terminal and CENTUM CS™ or XL™ or HART® 275 host.
