Micropilot FMR67 is the first 80 GHz radar designed in accordance with the international functional safety standard IEC 61508. With its droplet antenna, improved focusing and smaller beam angle, it is particularly suitable for measurement in narrow silos. FMR67 is suitable for continuous, non-contact level measurement of powdery to granular bulk solids. In addition, FMR67 is equipped with the Heartbeat Technology smart sensor function.

Advantages
Hardware and software design in accordance with IEC 61508, maximum safety SIL3 achievable in redundant systems
Heartbeat Technology ensures economical and safe operation of the device over its entire life cycle
The HistoROM data management concept enables quick and easy commissioning, maintenance and diagnostics
Small beam angle and multi-echo tracking algorithm ensure maximum measurement reliability in vessels with obstructions
The innovative droplet antenna made of PTFE provides the highest system suitability
80 GHz radar can be integrated into the process more conveniently, reducing engineering effort
The world's simplest proof test concept for SIL functions
