Application

The intrinsically safe 26 GHz. pulse radar transmitter provides continuous level measurement up to 98.4’ (30m) with a 4-20 mA analog and HART digital signal output, and is configured via its integral push button display module or WebCal software. The non-contact liquid level sensor is intended for petroleum, water, wastewater and diluted chemical storage or process conditions in above or below grade tanks of any material. Select this sensor for challenging process conditions with low or non-corrosive media, light surface foam or agitation, higher temperature or pressure, condensation or vapor, and installation in a tank adapter, flange fitting or metal stand-pipe. Typical applications include bulk storage, tanker truck, RO storage, process tank, waste sump and neutralization tanks.

Features

Rugged 316L stainless steel antenna and process mount

Configuration via push button display or WebCal software

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

HART communication in point to point and multi-drop modes

Auto-temperature compensation for accurate measurement

Fail-safe diagnostics with selectable signal fail-safe outputs

Recognition, storage and rejection of false echo signal returns

IP67 stainless enclosure with polycarbonate display window
