More informations

The conductive level switches of the model series FK14 are suitable for the direct activation of pumps, contactor and sig­nalling devices.

In case of an empty tank a low AC voltage (about 10 V) between the electrodes is applied. As soon as the medium touches the electrodes, a low AC voltage flows. The elec­trodes are available with a 1 point or 2 point control function. The level switch relays are equipped with a time delay. So a fluttering of the transistor output can be avoided. The sensitiv­ity of the electrodes are adjustable through a potentiometer (10 gears).

For realisation of minimum- and maximum switches the PNP- switch output can be inverted by changing the position of the jumper.

Typical applications

  • For level detection in tanks
  • with conductive liquids
  • Full- and empty-signal
  • Level control between two levels
  • Overflow protection
  • Dry run protection

Advantages

  • No moving parts
  • Independent from the specific weight of the medium
