An example of a tuning fork level sensor for sale

The Tuning Fork Level Switch is an ideal choice for level control of powders.  The Level Switch incorporates a piezoelectric crystal that vibrates the fork at its natural frequency.  Also, when the fork comes in contact with a material, the vibration is dampened and the switch changes state.

In addition, as the fork becomes free of material, the switch changes back to its normal state.  

Also, it’s compact size and DIN connection allow for application.  Applications in places a larger tuning fork level switch may not be suitable, providing great versatility.

The Level Switch is easy to use with no calibration required, and no mechanical moving parts mean no routine maintenance.

In addition, the Tuning Fork Level Switch is not affected by the dielectric constant of the sensed material, making it superior to a comparable capacitance level switch for applications where the dielectric constant is low, more than one material is being used in the single vessel, and when material moisture content can change.

Also, The Level Switch is also great for applications when the bulk density is too low for a rotating paddle level switch, making it the ideal choice for low density bulk solids and liquids.  Comes standard with a user friendly PNP/NPN configurable output.
