The GF Signet 2280 Tuning Fork are suitable for level detection of liquids or granular, powdered solids. Mounted on tanks filling / emptying can be controlled using these devices just as well they can generate fail-safe alarms providing overfill- or dry run protection.
The operation principle is based on the electronic circuit exciting the fork probe making it vibrate. As the medium reaches and covers the fork its vibration changes. The electronics senses the change of vibration and gives output signal after a selected delay.
Applications for the 2280 include:
Potable water
River water
Cooling water
