ESMYC 24vdc /220vac Powered tuning fork level switch for liquid solid particles
Working Principle
The tuning fork level switch drives the tuning fork to generate a natural vibration frequency of about 100Hz through piezoelectric ceramics. When the measured medium comes into contact with the tuning fork, the mass load of the vibration system changes, causing a shift in the resonant frequency, with a typical variation of about ±5Hz. The built-in microprocessor detects this frequency change and triggers a switch signal, thereby achieving level control.
Product Features
1.Strong adaptability: Unaffected by factors such as the density, conductivity, foam, or particle size of the medium. Harsh conditions like scaling, agitation, turbulence, bubbles, and vibration also do not impact detection, allowing stable operation under various complex working conditions.
2. Maintenance-free design: The tuning fork uses an integrated structure with no moving parts, making it resistant to damage and reducing the frequency of downtime for maintenance. Additionally, high-frequency vibration effectively prevents medium adhesion and provides self-cleaning capability.
3. Safe and reliable: Key components are made of corrosion-resistant materials, ensuring a long service life.
