Pepperl Fuchs LCL2

Capacitive limit switch. Limit switch for bulk solids, Device with rope probe, Rope probe can be shortened for optimum matching to the measuring point, 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. Measuring method: A 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 architecture: The 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 type: device with rope probe. Operating mode: MAX = 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 protectionMIN = 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.
