HiTECH Technologies, Inc. Goop-proof RF Switches

This series is an RF admittance point level sensor comprising an active  probe section, guard section and grounding section with insulation sleeves between the sections. This is designed to monitor for the presence or absence of target material by detecting the change of admittance between the active and grounding sections, which is caused by the change from material presence to absence or the reverse.

This features automatic build-up immunity which is helpful with sticky/accumulating target materials. The guard section eliminates the sensing of the material build-up, ensuring the accuracy and application reliability of the sensor.

Operating Principle:

RF

Features:

  • Universal power supply 20-250VAC/VDC
  • Local LED indication (certain versions)
  • Pushbutton calibration (SAL18 model)
  • Guard section provides automatic material build-up
    immunity
  • Pushbutton test function (SAL18)
  • Independent adjustable time delay, uncovered-tocovered
    and covered-to-uncovered (SAL18)
  • Remote test function
  • Bin temperature up to 842⁰F (450⁰C) available
  • Standard, mini, cable and high temperature probes

Application:

  • Concrete Production
  • Cement
  • Asphalt
  • Agriculture
  • Feed & Grain Processing
  • Plastic Processing
  • Food
  • Pharmaceutical
  • Chemical
  • Ceramic
  • Water/Wastewater
  • Steel

For Material Presence Detection

  • Trigger an alarm or illuminate an indicating light
  • Close a valve to shut off vessel filling of material
  • Open a valve to discharge material from a temporary storage vessel

For Material Absence Detection

  • Trigger an alarm or illuminate an indicating light
  • Close a valve to stop the discharge of material
  • Open a valve to begin filling vessel with material
