Capacitive limit switch LCL1

LCL1
  • Limit switch for bulk solids
  • Device with rod probe
  • Complete unit consisting of the probe and electronic insert
  • Integrated active build-up compensation: exact switch point, even with strong build-up
  • Mechanically rugged: no wearing parts, long operating life, maintenance-free

Please note: All product-related documents, such as certificates, declarations of conformity, etc., which were issued prior to the conversion under the name Pepperl+Fuchs GmbH or Pepperl+Fuchs AG, also apply to Pepperl+Fuchs SE.

General specifications
Measuring methodA metal plate at the end of the probe, within the insulation, and the surroundings (e. g. the silo walls) combine to form the two electrodes of a capacitor. If the probe is covered or free of material, then the capacitance changes and the LCL switches.
Equipment architectureThe measuring system consists of:
- the device
- a supply point
- the connected control systems, switching units, signalling systems (e. g. lamps, horns, PCS, PLC, etc.)
Construction typedevice with rod probe
Operating modeMAX = maximum safety:
The device switches if the probe is covered or if the supply voltage is disconnected in a safety-oriented manner (signal on alarm).
example application: overspill protection
MIN = minimum safety:
The device switches if the probe is uncovered or if the supply voltage is disconnected in a safetyoriented manner (signal on alarm).
example application: dry-running protection
