Product Description
The tuning fork level controller consists of two parts: the tuning fork mechanical resonance system and the circuit module. The tuning fork level controller is installed on the top or the side wall of the container. After power-on, the tuning fork body is driven by the crystal to vibrate. When the tuning fork body is submerged by liquid or covered by material, the vibration frequency of the tuning fork body changes. This frequency change is detected by the circuit module unit, and two sets of relay contact switch signals or 8mA and 16mA current switch signals are output for alarm and control.
