EJX210A Differential Pressure Transmitter
Brand: Yokogawa Electric CorporationThe high performance flange mounted differential pressure transmitter EJX210A can be used to measure levels of densities of solidifying or precipitating liquids.
EJX210A outputs a 4-20 mA DC signal corresponding to the measured differential pressure. Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via BRAIN or HART communications.
Other key features include quick response, remote set-up using communications, and diagnostics and optional status output for pressure high/low alarm.
The multi-sensing technology provides the advanced diagnostic function to detect such abnormality as an impulse line blockage. FOUNDATION Fieldbus and PROFIBUS PA protocol types are also available.
All EJX series models in their standard configuration, with the exception of the Fieldbus and PROFIBUS types, are certified by TUV as complying with SIL 2 for safety requirement.
