EchoPro® LR11 intrinsically safe 26 GHz pulse radar level transmitter provides continuous level measurement up to 32.8 ft. (10m) range with a 4-20 mA signal output and Hart digital signal output. The sensor is configured by a integral push button display module or HART communicator. This non-contact liquid level sensor is for chemical or water storage applications in above grade metal or reinforced concrete tanks or below grade tanks of any material. This sensor is for easy process conditions with corrosive media, light agitation, condensation or vapor and installation in a low-profile tank adapter or flange fitting. Applications include chemical bulk storage and tanker trucks.
Features
- Configuration via push button display or HART communicator
- IP67 stainless enclosure with polycarbonate display window
- LCD displays level in feet or meters with percent of span bar
