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)
Pressure: -1 to +16 bar (-14.5 to +266 psi)
Maximum measuring range: 50 m (164 ft)
Accuracy: ±3 mm (0.12 in)
W-Band: 80 GHz
International explosion protection certificates, SIL, ship approvals, 5- or 10-point factory calibration certificate

Benefits

Easy handling through intuitive operation and wizards, for commissioning and verification
Easier troubleshooting thanks to recommended actions in the display
Safety by Design: Device development according to IEC 61508
Increased productivity because of process monitoring, verification and diagnostics during operation with Heartbeat Technology
Easy device integration into asset management systems through digital communication
