Field of application

Micropilot FMR57 is the sensor for the highest demands in bulk solids and best suited for measurements in high silos, bunkers or stockpiles. The parabolic antenna facilitates very small emitting angles and thus the measurement in slim silos. Micropilot free space radar is used for continuous, non-contact level measurement in powdery to granular bulk solids. Dust, filling noises, temperature layers and gas layers do not affect the measurement.

Horn or parabolic antenna. Thanks to the additional air purge connection even strongly dusting and build-up forming media do not present any problem.
