Technical Characteristics and Design
-
Integrated Color Touch Display: The standout feature of the FMR30B is its high-resolution display. It provides clear visual feedback on level trends and device status. The touch interface allows operators to navigate setup wizards and perform Heartbeat verifications directly at the measurement point, even while wearing gloves.
-
80 GHz Precision: The high-frequency signal creates a very narrow beam angle, which is essential for avoiding false echoes in narrow tanks or silos with internal obstructions. This ensures the sensor remains locked on the product surface even in challenging geometries.
-
Heartbeat Technology: This suite provides continuous self-monitoring and allows for on-demand verification of the device’s health. The verification process is guided by an on-screen wizard, making it easy to generate a documented report for regulatory compliance without stopping the process.
-
Dual Access Operation: The FMR30B offers maximum flexibility by providing both on-site touch control and encrypted Bluetooth remote access. This allows maintenance teams to choose the most convenient method for commissioning or troubleshooting based on the environment.
-
It’s Me-Function: When connecting via Bluetooth, the user can trigger the local display to flash. This visual confirmation ensures that the operator is modifying the correct sensor, which is a critical safety feature in facilities with high sensor density.
-
Robust Compact Design: Despite its advanced display, the device remains compact and suitable for tight installation conditions. Its resilient construction makes it a reliable replacement for ultrasonic or mechanical sensors in dusty, humid, or outdoor locations.
