Yokogawa EJA430A-S1 Gauge Pressure Transmitter

The Yokogawa EJA430A-S1 Style S1 gauge pressure transmitter uses a DPharp resonant silicon sensor to deliver accurate gauge pressure measurements for liquids, gases, and steam in process control environments. It outputs a 4–20 mA DC signal with optional digital communications (HART/BRAIN/FF options), offering accuracy of ±0.065% of span and long-term stability around ±0.1% over 5 years. With a maximum working pressure up to ~3000 psi and loop-powered operation at 10.5–42 VDC, it mounts traditionally on pipe or wall brackets in the Style S1 configuration. Widely used in pipelines, compressors, pumps, and process systems, this transmitter supports applications across oil & gas, manufacturing, power generation, and utilities and is part of Yokogawa’s EJA-A platform for consistent measurement performance.
