Original and New Hart Protocol 4-20mA Yokogawa Eja110e Pressure Transmitter

Yokogawa EJA110E Differential Pressure Transmitter: Product Overview, Key Features, and Technical Specifications

Product Overview

The Yokogawa EJA110E is a high-performance differential pressure transmitter designed for precise measurement of liquid, gas, or steam flow, as well as level, density, and pressure in industrial processes. Utilizing the advanced DPharp digital sensor with single-crystal silicon resonant technology, the EJA110E delivers unparalleled accuracy, stability, and reliability. Launched in 2012 as part of Yokogawa's DPharp series, it combines rugged construction with cutting-edge digital innovation, making it a preferred choice for demanding industrial environments
 

Key Selling Points

1. Digital Sensor Technology

   • DPharp Digital Sensor: Directly outputs digital signals, eliminating analog-to-digital conversion errors and ensuring high precision (±0.055% reference accuracy) 
      
   • Dynamic Compensation: Simultaneously measures differential pressure (DP), static pressure (SP), and temperature, enabling real-time compensation for temperature and static pressure effects. This ensures accuracy under fluctuating operating conditions 
      

2. Enhanced Stability and Durability

   • Multidimensional Stability: Resists impacts from temperature, static pressure, and overpressure (up to 4,500 psi for specific models). The sensor's mechanical design protects against damage during abnormal pressure surges 
      
   • Overpressure Protection: Withstands incorrect valve operations or process upsets without requiring recalibration post-event 
      

3. Advanced Diagnostics and Safety

   • Self-Diagnostic Functions: Features 40 self-diagnostic capabilities, including Back-Check Technology, which verifies signal integrity via reverse calculations. The active DPharp sensor immediately detects faults, even if  remains unchanged 
      
   • Functional Safety: Complies with IEC 61508/61511 standards, achieving SIL 2 certification for single units and SIL 3 for redundant configurations 
      

4. Operational Efficiency

   • Fast Response Time: 90 ms for DP measurements, ideal for rapid process adjustments 
      
   • Extended Calibration Intervals: Long-term stability (±0.1% URL/10 years) reduces maintenance costs 
      

5. Versatile Integration

   • Multiple Communication Protocols: Supports HART 5/7, Foundation Fieldbus, PROFIBUS PA, and BRAIN, enabling seamless integration with control systems 
      
   • Local Parameter Setting (LPS): Adjust settings without external devices, minimizing downtime 
      

Technical Specifications

Applications

• Flow Measurement: Ideal for orifice plates, venturi tubes, and flow nozzles.
• Level and Density Monitoring: Suitable for tanks and reactors in oil/gas, chemical, and water treatment industries.
• Pressure Compensation: Used in steam systems and HVAC controls 
   

Maintenance and Support

• Built-In Display: Shows real-time data, alarms, and diagnostic codes for quick troubleshooting 
   
• FieldMate Compatibility: Enables remote configuration and management via PC 
   
• Universal Installation: Compatible with gas and liquid applications, reducing inventory complexity 
   

Certifications and Compliance

• Independent Certifications: Validated by TÜV Rheinland and EXIDA for performance and safety 
   
• Material Standards: Complies with NACE MR0175/MR0103 for corrosive environments 
   

Conclusion

The Yokogawa EJA110E sets the benchmark for digital pressure transmitters, offering unmatched precision, resilience, and adaptability. Its integration of dynamic compensation, robust diagnostics, and compliance with global safety standards makes it indispensable for industries prioritizing operational efficiency and reliability.
