EchoPro® LR31 intrinsically safe 26 GHz pulse radar level transmitter provides continuous level measurement up to 98.4ft. (30m) range with a 4-20 mA analog and Hart digital signal output. The sensor is configured by a remote push button display module or HART communicator. This non-contact liquid level sensor is for industrial wastewater, municipal storm or sewer lift station, reservoir, river, canal or open channel applications located above or below grade. This sensor is for challenging process conditions that include light surface foam or agitation, small trash or plant material, wind, condensation or vapor. Comes with a 32.8 ft. (10 m) cable, mounting bracket and display module. The sensor is designed to bracket mounting above the liquid level. Features Configuration via push button display or HART communicator Auto-temperature compensation for accurate measurement Wall mounted display with windowed enclosure rated IP67 LCD displays level in feet or meters with percent of span bar Optional display mode indicates the echo signal return curve Self diagnostics with selectable signal fail-safe signal outputs Recognition, storage and rejection of false echo signal returns 26 GHz. pulse radar is unaffected by sump process conditions 12 in.(30cm) dead band enables utilization of the entire sump Specifications 1 1/2 in.
