Overview:
The EJX110A is a premium differential pressure transmitter from the Yokogawa EJX-A series, engineered for exceptional precision and long-term stability. Leveraging DPharp silicon resonant sensor technology, it provides high-accuracy measurements of differential pressure, flow, and liquid level, even under challenging process conditions. Robust, corrosion-resistant construction and advanced diagnostic features make it ideal for safety-instrumented systems (SIS) and complex DCS networks.
