SLB Tuning Fork Level Switch
The SLB Tuning Fork Level Switch developed by S·HAO is a reliable level detection device designed for monitoring solid materials and liquids in industrial processes.
The instrument uses vibration frequency technology to detect the presence of material. When the fork is covered by material, the vibration frequency changes and the internal circuit outputs a switching signal.
This technology ensures stable operation, high sensitivity, and reliable detection even in challenging industrial environments.
Working Principle
The tuning fork level switch operates by vibrating a fork element at a specific resonance frequency. When the fork is exposed to air, it vibrates freely. Once the material covers the fork, the vibration frequency changes due to the damping effect of the material.
The electronic circuit detects this frequency change and converts it into a switching signal, which can be used to trigger alarms, control systems, or process automation equipment.
