The tuning fork level switch is designed with working principle of tuning fork vibration. It is the sensor rod based of tuning fork level switch. The tuning fork rod is driven by the piezoelectric crystal chip, and vibration signal is received by another piezoelectric chip, so that vibration signal can be circulated and the sensor rod can resonate. When the material is contact with the sensor rod, the vibration signal gradually becomes smaller, until the resonance stops, the control circuit will output an electrical contact signal. Due to the natural prince that sensitivity of the sensor rod gradual weakens from front to rear seat, when the material in the tank and the surroundings of the barrel accumulate upwards and touch the sensor rod base (rear) or discharge, no error signal will be generated. Simply put, the tuning fork produces mechanical vibration under the excitation of the piezoelectric crystal. This vibration has a certain frequency and amplitude. When the tuning fork is immersed in liquid or solid, the vibration frequency and amplitude of the tuning fork will change. This frequency change is detected by the electronic circuit and a switch value is output.

The tuning fork level switch is a new type of level switch. It is suitable for almost all liquid media, and it is also suitable for measuring free-flowing medium-density solid powders or particles. Since the tuning fork level switch basically has no moving parts, the mechanical wear is relative low, it is simple and convenient to use.

Adantages

Long service life, stable performance, safety and reliability, and strong adaptability (different electrical parameters and densities of the measured medium will not affect the measurement), No need to adjust (no matter what kind of medium is measured, no on-site adjustment is needed) and maintenance-free, etc. The tuning fork level switch is widely used in the process control of metallurgy, building materials, chemical industry, food and other industries.

Product catagory

Tuning fork level switches include small tuning forks, standard tuning forks, high temperature tuning forks and special customized tuning forks; among them, special customized tuning fork level switches can be customized according to site conditions (high temperature, extension, corrosion, etc.), and the color and type of the case it can also be customized!
