Yokogawa Electric Corporation EJA430A-EBS4B-94EA/SU1/S1 Gauge Pressure Transmitter

The Yokogawa EJA430A‑EBS4B‑94EA/SU1/S1 gauge pressure transmitter uses Yokogawa’s DPharp resonant silicon sensor to provide precise gauge-pressure measurements of liquids, gases, and steam. It outputs a 4–20 mA DC signal with digital communication (HART/BRAIN typical) and features SUS316L wetted parts for corrosion resistance in demanding industrial environments. Key specs include ±0.065% of span accuracy, ±0.1% stability over five years, a maximum working pressure up to approximately 3000 psi, and a 1/2" NPT process connection. The device is loop-powered from about 10.5 to 42 VDC and is used in process-control systems for measuring gauge pressure in pipelines, compressors, pumps, and other process systems across oil and gas, manufacturing, power generation, and utilities.
