Field of application
The Micropilot FMR66B belongs to the new generation of 80 GHz radar sensors. It is suitable for continuous, non-contact level measurement in simple solid applications. Wizards guide through commissioning, retesting and verification of the instrument and guarantee easy handling. The small beam angle is perfect for measurements in narrow silos. Heartbeat Technology detects unwanted anomalies, such as buildup, for increased productivity.
The Micropilot FMR66B is for free-field applications up to 50 m and provides high beam focus for vessels with many internal internals.
Process connections: Thread or mounting bracket
Temperature: -40 to +200 °C (-40 to 392° F)
