Key Benefits and Advantages
Specialized for Difficult Fluids: The EJX210B features a direct-mount flange design that allows the high-pressure side diaphragm to be installed flush with the tank wall. This prevents the accumulation of solids or precipitates, ensuring accurate level and density readings in processes involving slurries, polymers, or heavy oils.
Drastic Infrastructure Cost Savings: As a fully wireless, battery-operated instrument, the EJX210B eliminates the expense of signal cables, power wiring, and cable trays. This is particularly advantageous for large storage tanks, remote processing units, or retrofitting existing facilities where adding new wiring is physically difficult or cost-prohibitive.
Ultra-Low Power for Long-Term Service: Designed for maximum field uptime, the transmitter utilizes a low-current consumption architecture powered by two high-capacity lithium-thionyl chloride batteries. This setup provides years of continuous wireless operation, minimizing the maintenance burden and the frequency of site visits.
Assured Network Security: To ensure the integrity of the industrial wireless network, the EJX210B utilizes infrared (IR) communication for initial provisioning. This allows for secure wireless network joining and parameter configuration without exposing sensitive security keys over the airwaves.
Scalable Data Update Rates: The EJX210B offers high flexibility in data reporting, with selectable update times ranging from 0.5 seconds to 60 minutes. This allows operators to prioritize rapid feedback for dynamic control loops or conserve battery life for slow-moving bulk storage inventory.
Integrated Smart Diagnostics: Beyond transmitting process variables, the EJX210B provides comprehensive status and diagnostic data wirelessly. This enables proactive maintenance by monitoring battery health and sensor integrity from the comfort of the control room.
