| General specifications | ||
|---|---|---|
| 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 protection MIN = minimum safety: The device keeps the electronic switch closed as long as the fork is immersed in liquid. 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 fails (quiescent current principle) |

Function
The Vibracon LVL-A7 is a limit switch for liquids and is used in tanks, vessels and pipes. The device is used for overfill prevention or pump protection in cleaning and filter systems as well as in cooling and lubrication vessels, for instance.
The device is suitable for applications in which float switches or conductive, capacitance and optical sensors have been used up to now. The device also works in areas where these measuring principles are not suitable due to conductivity, buildup, turbulence, flow conditions or air bubbles.
The device can be used for process temperatures up to 150 °C (302 °F).
The device is not suitable for use in hazardous areas.
For hygienic areas we recommend the use of Vibracon LVL A7H.
