Yokogawa Gauge pressure transmitte
Product Description
EJA530E Gauge Pressure Transmitter,Yokogawa EJA530E Pressure Transmitter
The high performance absolute and gauge pressuretransmitter EJA510E and EJA530E feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure. EJA510E and EJA530E
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 and selfdiagnostics. FOUNDATION
Fieldbus, PROFIBUS PA and 1 to 5 V DC with HART (Low Power) protocol types are also available.
All EJA-E series models in their standard configuration, with the exception of the Fieldbus,PROFIBUS
and Low Power types, are certified as complying with SIL 2 for safety requirement.
