EchoPro® LR41 Radar Solids Level Sensor
The intrinsically safe 26 GHz. pulse radar transmitter provides continuous level measurement up to 229.7’ (70m) with a 4-20 mA analog and HART digital signal output, and is configured via its integral push button display module or HART communicator. The non-contact solids level sensor is intended for dry solid media including aggregates, grains, pellets, powders and building materials. Select this sensor for challenging process conditions with moderate to significant dust, and installation with an adjustable gimbal flange or mounting bracket. Typical applications include silos, stockpiles, transfer stations and crushers.
