Specifications
General specifications
| Order code (Pepperl+Fuchs part number) | 275573-100030 |
| Measuring method | The tuning fork is brought to its resonance frequency by means of a piezoelectric drive. If the tuning fork is covered by liquid, this frequency changes. The electronics monitor the resonance frequency and indicate whether the tuning fork is freely vibrating or is covered by liquid. |
| Construction type | device with short tube |
| Operating mode | MAX = maximum safety: The device keeps the electronic switch closed as long as the liquid level is below the fork. example application: overspill protectionMIN = minimum safety: The device keeps the electronic switch closed as long as the fork is immersed in liquid. example application: dry running protection of pumpsThe electronic switch opens if the limit is reached, if a fault occurs or in the event of a power fails (quiescent current principle) |
