Vibration Limit Switch

Сортировать по: Название   Цена  
Каталожный номер: 275573
General specifications
Measuring methodThe 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 typecompact device
device with short tube
Operating modeMAX = 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)

Measuring methodA 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).

Equipment architectureThe measuring system consists of:
- the device with electronic insert

General specifications
Function principlelimit detection
Maximum or minimum detection in tanks or pipelines containing all types of liquids including use in explosion hazardous areas. Particularly suited to very aggressive liquids thanks to high degree of corrosion protection.
Measuring methodThe forks of the sensors vibrate at their intrinsic frequency. This frequency is reduced when covered with liquid.
The change in frequency then activates the limit switch.

General specifications
Function principlelimit detection
Maximum or minimum detection in tanks or pipelines containing all types of liquids including use in explosion hazardous areas. Particularly suited to very aggressive liquids thanks to high degree of corrosion protection.
Measuring methodThe forks of the sensors vibrate at their intrinsic frequency. This frequency is reduced when covered with liquid.
The change in frequency then activates the limit switch.
