Solids Level Sensor
The intrinsically safe radar solids level sensor provides reliable level measurement of dusty grains, pellets, powders or aggregates in silo, bin, crusher, stockpile or transfer station applications from 3-30 meters. How does a radar solids level sensor work? The radar solids level sensor emits a high frequency RF pulse from its antenna. The pulse travels through the air gap, reflects against the solids surface and returns to the antenna. The radar solids level sensor determines the pulse time of flight and converts this into level height or distance.
