EJX530A In-Line Gauge Pressure Transmitter
Brand: Yokogawa Electric CorporationThe high performance absolute and gauge pressure transmitter EJX530A feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure.
EJX530A output a 4-20 mA DC signal corresponding to the measured pressure. It also features quick response, remote setup and monitoring via BRAIN or HART communications, diagnostics, and optional status output for pressure high/low alarm.
The multi-sensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage or heat trace breakage. 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 TÜV as complying with SIL 2 for safety requirement.
