YOKOGAWA EJA110E Differential Pressure Transmitter with 0.065% Accuracy SIL 2 / SIL 3 Certified and DPharp Digital Sensor
The YOKOGAWA EJA110E Differential Pressure Transmitter is part of Yokogawa's OpreX Field Instruments family under the OpreX Measurement category, representing the latest evolution of the DPharp (Digital Pressure Harp) family of pressure transmitters. Launched in 2012, it combines the ruggedness of the EJA-A series with the high performance of the EJX-A series, delivering exceptional accuracy and reliability for industrial measurement applications.
Equipped with Yokogawa's proprietary DPharp digital sensor—superior to traditional analog sensors in performance and stability—it ensures consistent, precise measurements even in demanding environments. Certified by Exida and TUV for SIL 2 / SIL 3, this transmitter is designed to meet the stringent requirements of industrial automation systems, offering advanced features such as fast response times, long-term stability, and robust resistance to overpressure and vibration.
- High Accuracy: Standard accuracy of 0.055%, with optional 0.04% accuracy for ultra-precise measurements
- Exceptional Stability: Maintains 0.1% stability per 10 years (for M, H, and V capsules) and 0.2% per year (for F capsules)
- Fast Response Time: 90 ms response time for quick detection of pressure changes
- SIL Certification: Exida and TUV certified for SIL 2 / SIL 3 safety-critical applications
- DPharp Digital Sensor: Advanced digital sensor with twice the performance and stability of analog sensors
- Overpressure Resistance: Withstands overpressure up to 2,300 psi (3,600 psi optional)
- Local Parameter Setting (LPS): On-site configuration without external tools
- Vibration Immunity: Stable performance in high-vibration environments
- Wide Pressure Range: Covers 0-100 MPa for diverse industrial applications
- Durable Construction: SS304 stainless steel for corrosion resistance in harsh conditions
