| 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 | compact device | |
| 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) |

Función
El Vibracon LVL-A7 es un interruptor límite para líquidos destinado a su uso en depósitos, recipientes y tuberías. El dispositivo se usa para la prevención de sobrellenado o la protección de bombas en sistemas de limpieza o de filtrado, así como en recipientes de enfriado y lubricación, por ejemplo.
El dispositivo es apropiado para aplicaciones en las que hasta ahora se han usado los interruptores de flotador o los sensores conductivos, de capacitancia y ópticos. Asimismo, el dispositivo puede funcionar en áreas en las que estos principios de medición no son apropiados debido a la conductividad, acumulación de elementos, turbulencias, condiciones de flujo o burbujas de aire.
El dispositivo puede utilizarse en temperaturas de proceso de hasta 150 °C (302 °F).
El dispositivo no es adecuado para su uso en zonas peligrosas.
Para zonas higiénicas, recomendamos el uso del Vibracon LVL A7H.
