NYYCUK - B Universal Limit Tuning Fork Switch IP67 44mm
NYYCUK-B Tuning Fork Switch Working 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
Output the electrical connection signal. The principle is that the sensitivity of the dry and salty bar is gradually weakened from the front to the back seat, so when the material in the barrel and the surrounding of the barrel are piled up, and the bell and the bar base (rear) or discharge, there will be no error. Set up signal. Simply put, the sound produces mechanical vibration under the excitation of the piezoelectric product, 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.
NYYCUK-B Tuning Fork Switch Design Feature
1.Suitable for measuring solid powders or particles of medium density that can flow freely. Also suitable for almost all liquid media, this series of tuning fork level switches can measure a variety of levels, with high/low fault safety limit switch.
2.Long service life, stable performance, safe and reliable.
3.It is not affected by foam, eddy current or gas, and is suitable for fixed-point alarm or control of solid material level in various silos and liquid level in various vessels. A variety of models can be suitable for different applications.
4.No need to adjust: Not affected by the dielectric constant and density of the measured medium, so no matter what kind of liquid is measured, there is no need for on-site adjustment.
5.Maintenance-free: The detection process of the tuning fork switch is completed by the electronic circuit, and there are no moving parts, so there is no need for on-site adjustment once it is installed and put into operation.
6.Strong adaptability: Different electrical parameters and density of the measured material have no effect on the measurement. Scaling, stirring, turbulence, bubbles, vibration, medium viscosity, high temperature, high pressure and other harsh conditions also have no effect on the detection.
