Radar Measurement Micropilot FMR60

Brand: Endress+Hauser Group Services AG

Micropilot FMR60 is the first 80GHz radar developed according to the international functional safety directive IEC 61508.

The free space radar offers maximum reliability due to the drip-off antenna, improved algorithms and small beam angle.

It is used for continuous non-contact level measurement of liquids, pastes and slurries.

The measurement is not affected by changing media, temperature changes, gas blankets or vapors.

It also possesses the smart sensor functionality Heartbeat Technology.

80GHz drip-off antenna suited for free space applications up to 50m and offers high beam focusing for vessels with many internal fittings.
