Minco’s functional level sensor designs are suitable for point detection in nearly any conductive fluid. They reliably and accurately detect the level of liquids and other fluids as well as rendered solids. Fluid presence is measured by passing a low voltage AC signal between two stainless steel probes.


Sensors can be installed into plastic and metal containers, suitable for use up to 185°F (85°C). The use of an AC voltage eliminates the effects of galvanic corrosion on the probes. The sensor indicates fluid is present with an 8mA output and a 16 mA output when fluid is not present. Level

Common applications include:

  • Radiator low-fluid level detection
  • Pump recovery tanks
  • Fluid leak detection
  • Parts washers
