Dpdt Tuning Fork Level Switch 44mm Slurry Vibrating Fork Liquid Level Switch

Tuning Fork Level Switch Liquid 

NYYCUK tuning fork level switch is a new type of level switch. It is suitable for almost all liquid media, but also for the measurement of free-flowing, medium-density solid powders or granules. Since the tuning fork level switch basically has no moving parts, the mechanical wear is relatively low, so it does not need maintenance and adjustment, and is simple and convenient to use.

In addition, the level switch adopts foreign new technology and original imported chips, which has the advantages of long service life, stable performance, safety and reliability, and strong adaptability (different electrical parameters and density of the measured medium will not affect the measurement) , No adjustment (no on-site adjustment is required no matter what medium is measured) and maintenance-free, it is widely used in the process control of material level in metallurgy, building materials, chemical industry, light industry, grain and other industries.

Tuning Fork Level Switch Liquid Technical Parameter

Tuning Fork Level Switch Liquid Measurement principle

NYYCUK tuning fork level switch is a new type of level switch. It is designed and manufactured using the principle of tuning fork vibration. It is on the base of the induction rod of the tuning fork level switch, the tuning fork rod is driven through the piezoelectric chip, and the vibration signal is received by another piezoelectric chip, so that the vibration signal can be circulated, and the induction rod can be resonated. When the material is in contact with the induction rod, the vibration signal gradually becomes smaller, until the resonance stops, the control circuit will output the electrical contact signal. Due to the natural principle that the sensitivity of the induction rod decreases sequentially from the front to the back seat, when the material in the tank and the surrounding of the barrel are piled up and touch the base of the induction rod (the rear) or discharge, no error signal will be generated. Simply put, the tuning fork generates mechanical vibration under the excitation of piezoelectric crystal, and this vibration has a certain frequency and amplitude. When the tuning fork is submerged 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 outputs a switch value.

Tuning Fork Level Switch Liquid Design Features

• Suitable for measuring free-flowing, medium-density solid powders or granules. Also suitable for almost all liquid media, this series of tuning fork level switches can measure a variety of levels, with high/low fail-safe limit switches, overflow or dry run protection, pump control, display pipeline with/without flow, etc.
• Not affected by foam, eddy current and gas, it is suitable for fixed-point alarm or control of solid material level in various silos and liquid level in various containers. Various models are available for different applications.
• Long service life, stable performance, safe and reliable
• Strong adaptability - different electrical parameters and densities of the tested materials will not affect the measurement. Harsh conditions such as scaling, agitation, turbulence, air bubbles, vibration, medium viscosity, high temperature, and high pressure have no effect on detection.
• No adjustment required: It is not affected by the dielectric constant and density of the measured medium, so no on-site adjustment is required no matter what kind of liquid is measured.
• Maintenance-free: The detection process of the tuning fork switch is completed by electronic circuits without moving parts, and once installed and put into operation, it does not require on-site adjustment.
