Yokogawa EJA110A-ELS4B-92EA/FF1/D1 Differential Pressure Transmitter

The Yokogawa EJA110A-ELS4B-92EA/FF1/D1 is a DPharp differential pressure transmitter designed for high-accuracy measurement of liquids, gases, and steam. It uses Yokogawa’s single-crystal silicon resonant sensor technology to deliver stable, long-term pressure readings and supports FOUNDATION Fieldbus (FF) communication as part of the EJA‑A series. Key specifications include ~0.065% typical accuracy, ~0.1% stability over 5 years, loop-powered operation from ~10.5–42 VDC, and maximum working pressure up to ~2300 psi class (model dependent), with a 4–20 mA equivalent output range in addition to digital communications. Applications span oil & gas, chemical processing, power generation, and water treatment, where differential pressure is used for flow, level, and density calculations in pipelines, tanks, and process systems.
