The high performance diff erential pressure transmitter EJA110E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, orsteam flow as well as liquid level, density and pressure. EJA110E outputs a 4 to 20 mA DC signal corresponding to the measured diff erential 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, 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 certified as complying with SIL 2 for safety requirement.
The EJA110E is a high - performance differential pressure transmitter by Yokogawa Electric Corporation. It features a single - crystal silicon resonant sensor and is designed to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure. The transmitter outputs a 4 - 20 mA DC signal corresponding to the measured differential pressure. It can also measure static pressure, which can be displayed on the integral indicator or remotely monitored via BRAIN or HART communications.

Output Signal | 4 - 20 mA HART/BRAIN (output signal code D&J), two - wire system with digital communication. The signal can be set to linear or square - root. The BRAIN or HART FSK protocol is superimposed on the 4 - 20 mA signal, and the output range is 3.6 mA - 21.6 mA. There is also a 1 - 5 V HART (output signal code Q) option, which is a three - wire or four - wire low - power type that can be set to linear or square - root. |
