| Measuring method | A piezoelectric drive excites the vibrating rod of the device to its resonance frequency. If medium covers the vibrating rod, the rod's vibrating amplitude changes (the vibration is damped). The electronics of the device compare the actual amplitude with a target value and indicates whether the vibrating rod is vibrating freely or whether it is covered by medium. | |
| Equipment architecture | The measuring system consists of: - the device with electronic insert - a supply point - the connected control systems, switching units, signalling systems (e. g. lamps, horns, PCS, PLC, etc.) | |
| Construction type | compact device | |
| 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 | |
