主なメリットと利点
Enhanced Measurement Accuracy: The EJA110E offers a standard reference accuracy of 0.055% of span. For applications requiring even tighter control, an optional 0.04% accuracy version is available, ensuring high-quality data for flow and level calculations.
Long-Term Field Stability: Built for durability, this transmitter maintains a stability rating of 0.1% per 10 years. This long-term consistency significantly extends calibration intervals, reducing maintenance labor and the total cost of ownership over the plant’s operational life.
High Static Working Pressure: The EJA110E is designed to operate in high-pressure environments, featuring a standard Maximum Working Pressure (MWP) of 2,300 psi. For more extreme conditions, an optional 3,600 psi MWP rating is available, providing a wide safety margin for industrial headers.
SIL 2/3 Certified Safety: Reliability is guaranteed with Exida and TUV SIL 2 / SIL 3 certification. This makes the EJA110E a trusted choice for Safety Instrumented Systems (SIS), allowing for seamless integration into safety loops where risk reduction is a top priority.
Rapid Response Performance: Featuring a quick 90 ms response time, the EJA110E enables control systems to react promptly to process fluctuations. This speed is essential for protecting sensitive equipment and maintaining steady-state operations in dynamic flow systems.
User-Friendly Field Configuration: The Local Parameter Setting (LPS) feature allows for direct adjustment of basic parameters at the transmitter site. This eliminates the frequent need for external handheld communicators, accelerating both initial commissioning and routine field troubleshooting.
