YOKOGAWA DPHARP EJ220-S1 PRESSURE TRANSMITTER 0-925.4mmH20 S STAINLESS 24VDC

Description:

The Yokogawa EJ220-S1 is a DPharp differential pressure transmitter designed for low-pressure measurement applications, with a calibrated range of 0–925.4 mmH₂O. It uses Yokogawa’s DPharp (Digital Pressure Sensor) technology, which measures pressure via a resonant silicon sensor, providing high accuracy, stability, and long-term reliability. The transmitter features stainless steel construction for corrosion resistance and is powered by a standard 24VDC loop.

Applications:

The Yokogawa EJ220-S1 transmitter is used in process control environments requiring precise low-pressure or differential pressure measurement. Common installations include cleanrooms, HVAC systems, filtration monitoring, tank level measurement, and low-pressure gas or air systems. The unit is widely used in industries such as pharmaceuticals, food processing, utilities, and manufacturing.
