  • For limit level sensing of bulk-solid, fragmental and extruded materials
  • Simple sensitivity setting by means of magnetic pen
  • Two or three-wire connections directly to the relay circuit or PLC logic unit
  • Wide range of supply voltage up to 230 V AC/DC (CLS–53N–SAC)
  • Optical indication by LED


The capacitive level switch CLS® is designed for limit (2-state) level sensing of bulk-solid materials (pellets, wooden chips, cereals, granulates, etc.) in hoppers, containers, silos, etc.

The sensor output is equipped with electronic switch. The sensitivity and output mode (normally open / closed) can be simply set by attaching a magnetic pen to the sensitive spot on the sensor housing.



  • CLS – 53N –SAC
    2-wire connection with electronic current switch directly connected to the relay circuit. Supply voltage up to 230 V AC/DC. The sensor is not suitable for direct connection to a binary input of the control system.

  • CLS – 53N –P(N)
    3-wire connection with NPN or PNP output for connected to Dinel supply and switching units or binary input of PLC.
