Yokogawa EJA530E Pressure Transmitter DPharp Sensor

The Yokogawa EJA530E DPharp gauge pressure transmitter delivers precise pressure measurements of liquids, gases, and steam in process systems, combining a rugged industrial housing with a DPharp single-crystal silicon resonant sensor. Key specs include ±0.055% of span accuracy, ±0.1% URL stability over 10 years, and a fast ~90 ms response time, with an output of 4–20 mA DC and optional digital communications (HART or Fieldbus) for real-time monitoring. Designed for in-line process connections, its model-dependent pressure range can reach up to roughly 50 MPa (7200 psi), and it uses corrosion-resistant wetted parts such as 316L or Hastelloy to suit demanding environments in oil & gas, chemical processing, power, water treatment, and manufacturing. Part of the Yokogawa EJA-E family, it serves as a modern replacement for legacy transmitters and aligns with common upgrades such as EJX530A, offering a robust solution for process control and safety-critical measurement.
