SC1700 Series Vibrating Probe Level Switch

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 which 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.
