APPLICATION

The intrinsically safe 26 GHz. pulse radar transmitter provides continuous level measurement up to 65.6’ (20m) with a 4-20 mA analog and HART digital signal output, and is configured via its integral push button display module or HART communicator. 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
  • Configuration via push button display or HART communicator
  • 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
  • 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
