EJA210A Flange Mounted Differential Pressure Transmitter
Brand: YokogawaThe high performance flange mounted differential pressure transmitter models EJA210A and 220A can be used to measure levels of densities of solidifying or precipitating liquids. Both output a 4 to 20 mA DC signal corresponding to the measured differential pressure.
Models EJA210A and 220A also feature remote setup and monitoring through communications with the BRAIN™ terminal and CENTUM CS™ or µXL™ or HART® 275 host.
