The Micropilot FMR43: Free Space Radar Sensor for Continuous Non-Contact Level Measurement in Hygienic Spaces
The Micropilot FMR43 is a free space radar sensor for continuous non-contact level measurement and part of the Compact Line. The product line is especially developed for hygienic applications and combines a compact design with full performance. The device ensures reliable measurement even under rapidly changing or turbulent process conditions. In addition to the proven 80 GHz technology, a 180 GHz frequency option ensures the use even in particularly small process tanks.
The Micropilot FMR43 is suitable for a wide range of hygienic applications:
- Mixing applications of viscous and low conductive media
- Filling applications of viscous media
- Storage of low conductive fluids
- Level measurement in tanks with changing media density
Benefits
- Outstanding ease of use due to easy setup and operation with guided wizards
- Improved process and product safety through configuration integrity – a checksum algorithm (CRC) ensures that safety relevant parameters remain unchanged
- Increased productivity thanks to traceable and documented on-demand verification including the radar’s accuracy without process interruption with Heartbeat Technology
- Documented compliance through certified hygienic design as well as proven material conformity and traceability
- Flexibility in scale – installation in tight space conditions thanks to compact sensor design and small process connections as well as use in large tanks and silos
