Hessman Tuning Fork Type Level Switch

The tuning fork level switch uses an electronic circuit to excite the piezoelectric crystal inside the fork, enabling the tuning fork to vibrate at a fixed frequency. When the fork is fully covered by measured medium, its vibration frequency changes. The built-in circuit detects this shift and converts it into relay switch signals for on-site alarming or remote control. After the medium leaves the fork, the device automatically returns to normal status and continues level monitoring.
