Key Benefits and Advantages
Precision Low Flow Architecture: The EJX115A features a factory-integrated orifice assembly that is precision-machined to capture minute pressure differentials in small-diameter lines (typically 1/2-inch to 1-inch). This integrated approach provides superior sensitivity compared to standard field-mounted orifice plates, ensuring reliable flow data even at the lower limits of the process.
Elite Square Root Accuracy: Engineered for maximum precision in flow calculation, the EJX115A delivers a 0.04% square root output accuracy. This high-tier performance ensures that the conversion from differential pressure to flow rate remains incredibly precise, minimizing measurement uncertainty in high-value fluid processes.
Market-Leading 15-Year Stability: Built for long-term reliability and reduced maintenance, the EJX115A offers a stability rating of 0.1% per 15 years for the differential pressure element. This unprecedented longevity allows for significantly extended calibration intervals, lowering the total cost of ownership and ensuring consistent performance for over a decade.
Certified for Safety-Critical Loops: The EJX115A is Exida and TUV SIL 2/3 certified, making it suitable for integration into Safety Instrumented Systems (SIS). Its robust design provides the dependable feedback required to prevent hazardous conditions caused by low-flow or no-flow scenarios in critical process lines.
Rapid Dynamic Response: With a response time of 90 ms to 150 ms, the transmitter provides near-instantaneous feedback to your control system. This speed is vital for managing fast-acting dosing pumps and ensuring stable regulation in processes with highly dynamic flow profiles.
Direct Field Configuration (LPS): The Local Parameter Setting feature empowers field technicians to perform range adjustments and basic setup via the external indicator. This streamlines commissioning and routine checks without the need for specialized handheld communicators.
