PTC thermistor level controllers

in-stock items

  • compact control unit
  • universal application due to selectable functions

For use in electrically conductive and non-conductive liquids which are not viscous or adhesive, such as fuel oil, diesel fuel and media which are not corrosive.

PTC thermistor type level controller with selectable functions:
Level switch (1 probe),
Level control for filling (2 probes),
Level control for emptying (2 probes)
Level switch with 1 probe:
The relay switches in case of contact or loss of contact with the liquid. When the switch point is set, it must be observed that the PTC thermistor requires approx. 8 seconds to heat up depending on the ambient temperature.
Level control for filling with 2 probes:
Set internal switch to "fill". The relay energises after the min. probe has heated up. Relay de-energises when the max. probe comes into contact with the liquid.
Level control for emptying with 2 probes:
Set internal switch to "empty". Relay energises when max. probe has contact with the liquid. Relay de-energises when the min. probe loses contact with the liquid and heats up.
