EJX510A, EJX530A Absolute and Gauge Pressure Transmitters

1 <<Contents>> <<Index>>. General EJX510A and EJX530A . Specifications Absolute and Gauge Pressure Transmitter GS 01C25F01-01EN [Style: S2]. The high performance Absolute and Gauge Pressure transmitter EJX510A and EJX530A feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam Pressure . EJX510A. and EJX530A output a 4 to 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 multisensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage or heat trace breakage.
