Radar Level Sensor
Offered in general purpose and intrinsically safe versions for liquid or solids, the radar level sensor provides reliable level measurement in difficult tank, sump or reservoir applications with foam, vapor, temperature or pressure; or dusty silo, bin, stockpile, crusher or transfer station applications with grains, pellets, powders or aggregates from 3-30 meters. How does a radar level sensor work? The radar level sensor emits a high frequency RF pulse from its antenna. The pulse travels through the air gap, reflects against the liquid or solids surface and returns to the antenna. The radar level sensor determines the pulse time of flight and converts this into level height or distance.
