EJA220A Flange Mounted Pressure Transmitter
Brand: Yokogawa Electric CorporationThe 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.
Features- 0.075% Accuracy
- 0.1% Stability per 5 years
- Flush Flange Process Connection (EJA210A)
- Extended Flange Process Connection (EJA220A)
