How does a tuning fork type level switch work?
A tuning fork type level switch uses a vibrating fork driven by a piezoelectric element. When material contacts the fork, the vibration frequency changes, which is detected and converted into a switching signal.
Can tuning fork level switches detect both solids and liquids?
Yes, a tuning fork type level switch for solids and liquids is designed to handle powders, granular materials, and various liquid types, including viscous and foaming media.
Does a tuning fork level switch require calibration?
No. A calibration-free tuning fork level switch operates independently of material properties such as density and dielectric constant.
Is the tuning fork level switch suitable for harsh environments?
Yes, this industrial tuning fork level switch performs reliably in:
- High temperature and pressure
- Turbulence and vibration
- Foam and buildup conditions
What safety certifications are available?
This SIL2 tuning fork level switch includes:
- Explosion-proof (Ex db)
