Key Benefits and Advantages
High-Precision Measurement Performance: The EJA440E provides a standard reference accuracy of ± 0.055% of span. This level of precision ensures that even in high-pressure processes, your control system receives accurate data to maintain optimal efficiency and product quality.
Proven Long-Term Stability: Reliability is a hallmark of the EJA-E series. The EJA440E offers a stability rating of ± 0.1% per 10 years, which significantly reduces the need for frequent maintenance and re-calibration. This long-term consistency ensures a lower total cost of ownership (TCO) over the life of the plant.
Certified Safety and Reliability: For use in safety-critical applications, the EJA440E is Exida and TUV SIL 2/3 certified. This certification provides peace of mind that the transmitter can be seamlessly integrated into Safety Instrumented Systems (SIS), meeting the most stringent global safety standards.
Rapid Process Response: In dynamic high-pressure systems, speed is essential for protection. With a response time of 90 ms, the EJA440E ensures that fluctuations in pressure are detected and communicated to the control room almost instantaneously, preventing potential system stress.
Flexible Field Configuration: The Local Parameter Setting (LPS) feature allows technicians to perform essential setup and configuration tasks directly at the transmitter. This user-friendly interface reduces the reliance on external handheld tools, streamlining both commissioning and on-site troubleshooting.
Advanced Communication Versatility: To ensure compatibility with any modern control architecture, the EJA440E supports a wide array of protocols, including HART 5/7, 1 to 5 VDC HART 7 (Low Power), FOUNDATION Fieldbus, PROFIBUS PA, and BRAIN.
