Pepperl Fuchs LCL1

Capacitive limit switch. 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. 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 rod 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.
