General specifications
| 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 |
