The general purpose vibration point liquid level switch provides high or low liquid level detection of dirty liquids or those with light to medium coating or scaling characteristics with a 1A relay output. Media examples include wastewater, diluted caustic soda and copper sulfate. For optimum performance, the sensor automatically adjusts for coating build up, and if necessary, outputs a proactive maintenance alarm to request cleaning. The submersible PP-Ryton® level switch sensor is universally mounted through the tank wall or inside the tank, and connected to a PLC or relay controller.


  • Automatic coating adjustment optimizes sensor performance
  • Submersible Ryton® sensor with polypropylene cable for corrosive liquids
  • Maintenance alarm proactively alerts user if sensor cleaning is required
  • 60VA SPST relay selectable NO or NC via power supply wiring polarity
  • Compatible with Smart Trak and Switch-Pak installation fittings
