Vibrating Probe Level Switch – Finetek SCX

The Finetek vibrating probe switch is highly versatile and can be used for most almost any bulk solid application. This includes level detection of almost any granular, sandy, chip-like, foodstuff, grain, or powdery materials. The operating principle is based on the changes of vibration frequency of the tuning fork when it comes into contact with a liquid or solid material. The Vibrating probe contains piezoelectric crystals built into the vibration tube that produce vibrations/resonations at specific frequencies. One element acts as a transmitter of the signal and the other receives the signal and converts it to electrical output. When the Vibrating probe comes in contact with material the vibration is weakened/dampened and results in a frequency change that triggers the switch. It’s ideal for applications where: the dielectric constant is low (where capacitance level switches can’t be used); when material moisture content changes easily; low viscosity liquids; there is a combination of differing materials in the container/tank. The Vibrating probe provides a reliable & maintenance-free means of process control for bulk solids. Easy mounting at almost any angle and basic calibration procedures will provide reliable functioning and less required monitoring. This device can withstand tough lateral loads and static electricity. Furthermore, it eliminates the application issues associated with jamming and clogging between tines on a ‘tuning fork’ device Also; it is equipped with a Fail-safe that prevents malfunctioning caused by power cuts.
