Detailed introduction
Yokogawa EJA530E High-Performance Pressure TransmitterIt is the next model in the Chongqing Chuan Instrument Yokogawa EJA Transmitter-E series, a directly mounted, high-performance gauge/absolute pressure transmitter. It uses single crystal silicon resonant sensor technology, suitable for measuring the pressure of liquids, gases, or steam. The Yokogawa EJA530E high-performance pressure transmitter (directly mounted) converts pressure into a 4-20mA DC current signal output, featuring fast response, remote setting, self-diagnosis, and other functions. The Yokogawa EJA smart transmitter is a new product from Yokogawa Electric Corporation's DPharp series, which first adopts digital sensors—single crystal silicon resonant sensors. The sensor outputs a pair of differential digital signals, directly eliminating external interference in the sensor part, creating a new era for transmitters. The product has higher accuracy (±0.055%), greater stability, and reliability, and has received widespread acclaim since its market launch.
Here’s a distilled list of the key features of the Yokogawa EJA530E high-performance pressure transmitter:
High Accuracy: Standard ±0.055% of span; optional ultra-high accuracy of ±0.04%
Exceptional Stability: ±0.1% of URL per 10 years for minimal recalibration needs
Fast Response: 90 ms response time—ideal for dynamic process control
Signal Customization: 10-point linearization for complex process curves (e.g., tank strapping, flow correction)
Safety Ready: SIL2/SIL3 certified (per IEC61508) by Exida and TÜV—suitable for safety instrumented systems (SIS)
Advanced Display: Local indicator with configurable graphical/textual info, independent of 4–20 mA signal
Robust Construction: Designed for in-line gauge pressure measurement in harsh industrial environments
Comms Flexibility: HART 7 protocol standard; FOUNDATION Fieldbus and PROFIBUS options available
Global Certifications: Explosion-proof, intrinsically safe, and flameproof approvals for global use
