| 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 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 |
