Yokogawa EJA120E Draft Range Differential Pressure Transmitter Stainless Steel Enclosure


Details:

The Yokogawa EJA120E is a high-performance micro differential pressure transmitter. It utilizes single-crystal silicon resonant sensor technology and is suitable for measuring the flow, liquid level, density, and pressure of liquids, gases, or steam. The EJA120E converts the measured differential pressure into a 4- 20mA DC signal output, featuring rapid response, remote setting, and self-diagnosis functions. It supports multiple communication protocols such as HART 5/7, HART (1~5V DC) low-power type, FF fieldbus, PROFIBUS PA, and BRAIN

Key Features

  • Superior Accuracy: Achieves ±0.2% standard accuracy, with an optional upgrade to ±0.09% for enhanced precision.

  • Exceptional Long-Term Stability: Maintains ±0.3% per year, ensuring consistent and reliable performance over extended periods.

  • Rapid Response Time: Delivers 150ms response time, providing fast and accurate readings for real-time monitoring.

  • Certified for Safety Applications: Holds SIL 2 / SIL 3 certification from Exida and TUV, making it ideal for safety-critical processes.

  • User-Friendly Configuration: Features Local Parameter Setting (LPS) for easy setup and adjustments without external tools.

  • Optimized for Low-Pressure Applications: Specifically designed for draft range measurements, ensuring precise control in sensitive environments.

  • Flexible Communication Options: Supports HART 5/7, FOUNDATION Fieldbus, PROFIBUS PA, and BRAIN protocols for seamless integration.
