MVVF 40 mm NPN,PNP SPDT Vibrating Fork Level Switch.

Product Features
The MVVF Series Vibrating Fork Type Level Switch consists of a piezoelectric tuning fork component that produces vibration on the fork
and a unit that sends a signal by measuring the frequency of this vibration.
When the fork comes into contact with the measured material, the vibration frequency changes.
When the electronic unit detects the change in the frequency signal, it converts this data into a signal output.
