Flowline EchoPro® LR41 Solid Level Sensor Transmitter w/ 26 GHz Pulse Radar, 229.7 ft. Range, Intrinsically Safe

EchoPro® LR41 intrinsically safe 26 GHz. Pulse radar transmitter provides continuous level measurement up to 49.2 ft. (15m) range, with a 4-20 mA analog and Hart digital signal output. The sensor is configured by a integral push button display module or HART communicator. This non-contact solids level sensor is for dry solid media including aggregates, grains, pellets, powders, and building materials. Applications include bins, transfer stations and crushers. This sensor is for easy process conditions with minimal dust and installation with and adjustable mounting bracket or gimbal flange.
