2. Design and function
2.1 Functional description
Tuning fork level switch is a universal level switch. The core component
of the tuning fork level switch is the vibration drive device located in the
fork body, which drives the fork body to reach its resonant frequency.
When the fork body is immersed by the medium, the frequency of the
fork body decreases, and the frequency change is detected by the
electronic circuit and converted into a switching signal to achieve the
purpose of liquid level alarm or control.
