Yokogawa EJA310 Style-S2 Absolute Pressure Transmitter

The Yokogawa EJA310 Style S2 Absolute Pressure Transmitter delivers precise absolute pressure measurements for liquids, gases, and steam using Yokogawa’s DPharp resonant silicon sensor. It outputs a 4–20 mA current signal with digital communication options (HART, BRAIN, Fieldbus) for integration into modern control networks. With typical accuracy around ±0.2% (±0.075% optional depending on capsule) and long-term stability near ±0.1% per year, it supports reliable process monitoring and is powered by a loop supply of 10.5–42 VDC. The Style S2 housing is designed for standard process mounting and supports pipe, wall, or bracket mounting, with maximum overpressure up to 10,000 psi class depending on the model; the EJA310A series is a legacy model, later replaced by EJA310E/EJX310A platforms, with common replacements including Yokogawa EJA310E and EJX310A.
