1. Cutting-Edge Sensor Technology
DPharp® Digital Sensor: The EJA530E utilizes Yokogawa's patented single-crystal silicon resonant sensor (DPharp), which outputs digital signals directly, eliminating analog-to-digital conversion errors. This ensures ±0.055% reference accuracy, outperforming traditional analog sensors
Active Sensing: Unlike passive sensors, the DPharp continuously generates frequency signals even when pressure remains static. This allows immediate fault detection (e.g., sensor failure) without misinterpreting zero output as unchanged pressure
Long-Term Stability: With ±0.1% URL stability over 10 years, the EJA530E minimizes drift, reducing recalibration frequency and lifecycle costs
2. Enhanced Diagnostics and Safety
Self-Diagnostic Capabilities:
40+ Built-in Diagnostics: Includes Yokogawa's exclusive Back-Check™ Technology, which performs real-time reverse calculations to verify signal integrity and computational accuracy
