The Intempco LLS100 Conductivity Level Switch can be used in harsh environments, for liquid level limit detection in metallic and non-metallic tanks containing electrically conductive liquids. The probe, fitting and housing are constructed of stainless steel 316; the isolator is Teflon. The LLS100 sensor features built-in protection against reverse polarity, overvoltage and electrical shielding to deliver long-term reliability. The output is relay SPDT which can be configured as either NO or NC (4-wire) or both NO and NC (5-wire).

Applications include:

  • Limit detection of conductive liquids
  • Water level monitoring in oil separators
  • Steam boilers
  • Waste water level monitoring
  • Leak detection
  • Coolant level monitoring
