EchoPulse® LR20 Radar Liquid Level Sensor Transmitter
APPLICATION
The general purpose 26 GHz. pulse radar level transmitter provides continuous level measurement up to 65.6’ (20m) with a 4-20 mA signal output, and is configured via its integral push button display module. The non-contact liquid level sensor is intended for chemical storage or process applications in above or below grade tanks of any material. Select this sensor for challenging process conditions with corrosive media, light surface foam or agitation, higher temperature or pressure, condensation or vapor, and installation in a flange fitting. Typical applications include bulk storage and process tanks.
FEATURES
316L antenna with PTFE inner shield for corrosive media
Simple configuration via integral push button display module
26 GHz. pulse radar is unaffected by vapor or condensation
12” (30cm) dead band enables utilization of the entire tank
LCD displays level in feet or meters with percent of span bar
Optional display mode indicates the echo signal return curve
Fail-safe diagnostics with selectable signal fail-safe outputs
Recognition, storage and rejection of false echo signal returns
Rugged IP67 aluminum enclosure with polycarbonate window
