SPX500 Series Vibration Tuning Fork Level Switch Sensor

The tuning fork liquid level switch works by vibrating the tuning fork at a certain resonant frequency through a pair of piezoelectric crystals mounted on the tuning fork base. When the tuning fork of the tuning fork liquid level switch is in contact with the measured medium, the frequency and amplitude of the tuning fork will change. These changes of the tuning fork liquid level switch are measured by the intelligent circuit, processed and converted into a switching signal.

Category

The tuning fork level switch is also often called the tuning fork level meter or the tuning fork level controller, mainly because the tuning fork level meter appears in different links in industrial production, and the actual key functions are different, so people are habitual called many different names. Tuning fork level switch is a kind of level switch. It mainly uses the resonance principle of tuning fork to measure the level state. Its unique fork body design and its inherent vibration characteristics can ensure the automatic cleaning function of the tuning fork and prevent material hanging to the greatest extent. .
Tuning fork level switch has the characteristics of long service life, stable performance, safety and reliability, as well as strong adaptability, no adjustment and maintenance-free. It is mainly used in metallurgy, building materials, chemical industry, light industry, grain and other industries. process control. It is not affected by foam, eddy current and gas, and is suitable for fixed-point alarm or control of solid material levels in various silos and liquid levels in various containers.
Measuring medium: dry particles, powdery materials and various liquids, slurries, etc.
Solid materials: fly ash, cement, stone powder, plastic particles, salt, sugar, etc.
