Yokogawa Pressure Transmitter EJX120A-EES5G-819DB
The high performance draft range EJX120A features single crystal silicon resonant sensor and is suitable to measure liquid,gas, or steam flow as well as liquid level, density and pressure. EJX120A-EES5G-819DB outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure.Other key features include quick response, remoteset-up using 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.
