Key Benefits and Advantages
Superior Performance Over Capillary Systems: Unlike traditional diaphragm seal systems that suffer from temperature-induced errors and signal lag in long capillary runs, the EJXC40A uses digital communication between sensors. This eliminates the “chimney effect” and ambient temperature fluctuations, providing much higher accuracy and faster response times for tall tank level measurement.
Optimized for Tall Tanks and Large Skids: With a maximum DRS dedicated cable length of up to 45 meters (approx. 147 feet), this system is specifically engineered for large-scale assets. It is the ideal solution for tall distillation columns, fermentation tanks, and storage vessels where the distance between high and low pressure taps is significant.
Advanced Signal Characterization: The EJXC40A features built-in signal characterization capabilities tailored for various tank geometries. This ensures precise volume and level calculations for horizontal cylinders, spherical tanks, and other complex shapes, reducing the need for external calculation logic in the PLC or DCS.
Certified Safety and Reliability: Safety is integrated into the digital architecture of the DRS system. The EJXC40A is Exida SIL 2/SIL 3 certified, making it a trusted component for Safety Instrumented Systems (SIS) and critical process control loops where accidental failure must be minimized.
High-Accuracy Digital Sensing: By utilizing the proven DPharp sensor technology in both the primary and secondary units, the system delivers high-precision measurement for liquid, gas, and steam flow. The digital link ensures that no signal loss or interference occurs between the two sensing points.
Reduced Installation and Maintenance Costs: The flexible DRS communication cable is easier to install and route than rigid or oil-filled capillaries. Furthermore, the absence of fill fluids in long runs eliminates the risk of leaks and reduces the complexity of maintenance during plant turnarounds.
