CLC40 conductive level indicator for liquids

Conductive level switch designed to independently monitor two level thresholds for liquids. Also enables a signalling delay to be set. Current flow between two electrodes immersed in a conductive liquid switches a signal relay.



  • Easily installed Specific tools are not required.
  • Versatile: can be installed in the vertical, horizontal or oblique positions.
  • Sensitivity can be adapted to the conductance of the liquid
