1 <<Contents>> <<Index>>. General EJA110E . Specifications Differential Pressure transmitter GS 01C31B01-01EN. The high performance Differential Pressure transmitter EJA110E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density and Pressure . EJA110E outputs a 4 to 20 mA DC signal corresponding to the measured Differential Pressure . Its accurate and stable sensor can also measure the static Pressure which can be shown on the integral indicator or remotely monitored via BRAIN or HART. communications. Other key features include quick response, remote set-up using communications and self-diagnostics. FOUNDATION Fieldbus and PROFIBUS PA protocol types are also available. All EJA-E series models in their standard configuration, with the exception of the Fieldbus and PROFIBUS. types, are certified as complying with SIL 2 for safety requirement.
