YOKOGAWA EJA430A EBS4B-94EA SU1 ,S1 SUS 430 TRANSMITTER 4-20MA 1 2" NPT,BP

Description:

The Yokogawa EJA430A-EBS4B-94EA/SU1/S1 is a DPharp gauge pressure transmitter designed for accurate measurement of liquids, gases, and steam. It uses Yokogawa’s resonant silicon sensor technology to deliver high accuracy, long-term stability, and reliable performance in industrial environments. The unit outputs a standard 4–20 mA signal with digital communication and is built with stainless steel (SUS) wetted parts for corrosion resistance.

Applications:

The Yokogawa EJA430A transmitter is used in process control systems for measuring gauge pressure in liquids, gases, and steam. The Yokogawa transmitter is commonly installed in pipelines, compressors, pumps, and process systems for pressure monitoring and control in industries such as oil & gas, manufacturing, power generation, and utilities.
