1. Product Overview:The Yokogawa EJA110E high-performance differential pressure transmitter is the most common standard traditional installation high-performance differential pressure transmitter in the Yokogawa EJA transmitter - E series. The Yokogawa EJA110E differential pressure transmitter also uses single crystal silicon resonant sensor technology, making it very suitable for measuring the flow, liquid level, density, and pressure of liquids, gases, or steam. It can convert the measured differential pressure into a 4~20mA DC current signal output, allowing for measurement, display, or remote monitoring of static pressure, with features such as fast response, remote setting, and self-diagnosis.

Here’s a breakdown of the key features of the Yokogawa EJA110E differential pressure transmitter:

High Accuracy: ±0.055% of span standard; option available for ±0.04% for even more demanding applications.

Outstanding Long-Term Stability: Maintains ±0.1% stability over 10 years—ideal for critical process environments.

Rapid Response Time: 90 ms response supports fast-changing processes and tight control loops.

Multi-variable Measurement: Simultaneously detects differential pressure, static pressure, and temperature for dynamic compensation.

Multiple Communication Protocols: Supports HART, FOUNDATION Fieldbus, PROFIBUS PA, and low-power analog signals.

Robust Safety Certifications: SIL 2 certified for single use and SIL 3 for redundant configurations, enhancing safety in hazardous areas.

Advanced Diagnostics: Built-in self-diagnostics help reduce downtime and improve process reliability.

Rugged Design: Resistant to harsh environmental conditions with excellent overpressure protection and wide operating temperature range.

Compact and Lightweight: Easier installation without sacrificing durability or performance.
