EJA120E-JES4J-912EN Yokogawa Draft Range Differential Pressure Transmitter

The high performance draft range diff erential pressure transmitter EJA120E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam fl ow as well as liquid level, density and pressure. EJA120E outputs a 4 to 20 mA DC signal corresponding to the measured diff erential pressure.
Other key features include quick response, remote set-up using communications and self-diagnostics. FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 V DC with HART (Low Power) protocol types are also available. EJA-E series models in their standard confi guration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certifi ed as complying with SIL 2 for safety requirement.

EJA120E features include:

• ± 0.2% Accuracy (0.09% available with /HAC option)
• ± 0.3% per 1 year Stability
• 150 ms Response Time
• Exida and TUV SIL 2/3 Certified
• Local Parameter Setting (LPS)
• True Draft Range design
