Selex Liquid Level Sensors

Selex Liquid Level Sensors

Product Features

  • Liquid sensing by detection of free ions
  • High immunity to probe deposits
  • Full galvanic isolation
  • FET output to drive solenoid valve / relay
  • 110Vac, 230Vac or 5Vdc powered
  • Time delay to avoid nuisance switching

The Tempatron Selex liquid level sensors control the levels of conductive liquids by using advanced solid state ferromagnetic technology to sense the presence of liquid by detecting the free ions within it. They are ideal for applications where significant build up of deposit on the probes can occur, e.g. with adhesives or systems in hard water areas. They are available in 110Vac and 230Vac versions with a FET output (to drive a relay or solenoid valve) and 5Vdc powered versions with an NPN transistor output. The sensors pass no measurable current through the liquid and provide full galvanic isolation between the supply, inputs and outputs. These sensors pcb mount, have an integral 5 second delay to avoid nuisance switching and require two mutually isolated metallic probes, one of which can be the container itself.
