| Produkt beskrivelse |
|---|
| Vibration Limit Switch |
| Application | ||
|---|---|---|
| Function principle | 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. | |
| Input characteristics | ||
| Measured variable | density | |
| Measuring range | min. 0.7 g/cm3, other density (e. g. 0.5 g/cm3) settings on request | |
| Output characteristics | ||
| Fail-safe mode | minimum/maximum closed circuit safety The limit switch can be connected in two operating modes, depending on the operating mode selected (MAX or MIN safety). The limit switch will switch off safely in the event of a fault (e. g. if the power supply line is interrupted). MAX = maximum safety: The device keeps the electronic switch closed as long as the fluid level is below the fork. example application: overspill protection MIN = minimum safety: The device keeps the electronic switch closed as long as the fork is immersed in fluid. example application: dry running protection of pumps The electronic switch opens if the limit is reached, if a fault occurs or in the event of a power failure. |
