- Model FMR67 - Radar Measurement



The standard sensor for highest demands in bulk solids level measurement with 80GHz technology. Micropilot FMR67 is the first 80GHz radar developed according to the international functional safety directive IEC 61508. It offers maximum reliability due to the drip-off antenna, improved focusing and very small emitting angles which is perfect for the measuring in slim silos. FMR67 is used for continuous, non-contact level measurement in powdery to granular bulk solids. FMR67 also possesses the smart sensor functionality Heartbeat Technology.

  • Hardware and software developed according to IEC 61508 up to SIL3 in homogeneous redundancy

  • Heartbeat Technology for a cost-effective and safe plant operation during the entire life cycle

  • HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics

  • Highest reliability even with obstructions in vessels due to small beam angle and Multi-Echo Tracking evaluation

  • Innovative drip-off antenna of PTFE for maximum system availability

  • Reduction of engineering effort due to an easier integration of the 80GHz radar instrument into the process

  • The world's easiest proof test concept for SIL saves time and costs

Micropilot FMR67 is suited for free space applications up to 125m and offers high beam focusing for vessels with many internal fittings.
