Detailed introduction
1. Product Overview:
The Yokogawa EJA530A is an in-line mount gauge pressure transmitter from the EJA-A series—Yokogawa’s long-standing workhorse line known for reliability and performance. Although it was officially discontinued on December 29, 2016, it still sees use in legacy systems and has been succeeded by the EJA530E model.
Here are some key specs of the EJA530A:
Accuracy: ±0.2% of span (with an optional ±0.075% for certain capsule codes)
Stability: ±0.1% of URL per year
Maximum Working Pressure: 8,500 psi
Sensor: DPharp digital sensor for enhanced diagnostics and performance
Mounting: In-line, ideal for applications requiring compact installation
