Yokogawa Differential Pressure Transmitter

The eja210e differential pressure level transmitter is a high-performance instrument within the DPharp EJA-E series, specifically designed for measuring the liquid level and density of fluids in tanks. Utilizing Yokogawa's proprietary digital sensor technology, the EJA210E eliminates the static drift and temperature effects common in analog sensors. This robust design ensures accurate measurements even in dynamic process environments, empowering operators to maintain optimal levels, prevent overflow, and enhance overall plant safety while minimizing maintenance requirements.

Key Features and Technical Specifications

High Accuracy: Delivers a reference accuracy of ±0.075% of span, ensuring precise level monitoring for critical inventory management.
Fast Response: Features a 120-millisecond response time, allowing for immediate reaction to rapid level changes.
Active Diagnostics: Equipped with advanced digital diagnostics that predict issues such as impulse line blocking before they impact operations.
Safety Certified: Standard compliance with IEC 61508 for SIL 2 (single) and SIL 3 (dual) safety applications, reducing risk without extra cost.
Flexible Installation: Available in flush and extended diaphragm types to suit various tank nozzle configurations and fluid characteristics.

Industry Applications and Smart Capabilities

The EJA210E is ideal for the Oil & Gas, Chemical, and Water/Wastewater industries, particularly for applications involving slurries, viscous fluids, or media prone to crystallization. Its flange-mounted design allows for direct connection to the process, minimizing potential leak points. The transmitter supports robust communication protocols including HART, FOUNDATION Fieldbus, and PROFIBUS PA. By deploying the eja210e differential pressure level transmitter, facilities can leverage multi-sensing capabilities-simultaneously monitoring differential pressure and static pressure-to gain a comprehensive view of tank conditions and drive operational efficiency.
