Versatile Material Level Switch Series Tuning Fork Switch for Different Process Connections and Fluid Densities

Product Description

The working principle of tuning fork switch is to make the tuning fork vibrate at a certain resonant frequency through a pair of piezoelectric crystals installed on the tuning fork base. When the tuning fork of the tuning fork level switch contacts the measured medium, the frequency and amplitude of the tuning fork will change. These changes of the tuning fork level switch are detected, processed and converted into a switching signal by the intelligent circuit.

Specification of Tuning Fork Switch

Product Features
1.It is practical and simple, reliable, and applicability;
2.Tuning fork and output were working condition, all with LED indication;
3.It may indicate that under customary adjustment;
4.A variety of input and output.

Working Principle
The vibrating fork liquid level switch is a new type of liquid level switch. It is designed and manufactured using the principle of tuning fork vibration. It is the base of the induction rod of the tuning fork level switch. The tuning fork is driven by the piezoelectric wafer, and the vibration signal is received by another piezoelectric wafer, so that the vibration signal can be circulated and the induction rod resonates. When the material contacts the sensor bar, the vibration signal gradually becomes smaller, and the control circuit outputs an electrical acceptance signal until the resonance stops.

Application

t is suitable for measuring medium density solid powder or particles that can flow freely. It is also applicable to almost all liquid media. It has the functions of high / low fault safety limit switch, overflow or idling protection, pump control, indicating whether there is flow in the pipeline, etc.
The tuning fork switch can measure a variety of material levels and has the functions of high / low fault safety limit switch, overflow or idling protection, pump control, and displaying whether there is flow in the pipeline.
Tuning fork switch is mainly used in challenging liquids, including sewage with junction layer and impurities and industrial liquids such as hydrochloric acid and sodium hydroxide.
Tuning fork switch is not affected by foam, eddy current and gas. It is suitable for fixed position alarm or control of liquid level in solid materials and various containers. A variety of models can be suitable for different applications.
The tuning fork switch adopts foreign new technology and original imported chip. It has the advantages of long service life, stable performance, safety and reliability, strong adaptability (different electrical parameters and density of the measured medium have no impact on the measurement), no adjustment (no field adjustment is required for any medium measured) and maintenance free. It is widely used in metallurgy, building materials, chemical industry Process control of material level in light industry, grain and other industries.

Tuning fork switches are usually used with level meters to control and measure materials. It is mainly aimed at the powder and small particle materials with a wide range of density, such as the detection of inlet and outlet pipe blockage of the dust collector, the material level measurement of the ash hopper of the dust collector, and the limit measurement of plastics, rubber powder, flour, various grain crops, food, chemical products and so on. For all kinds of liquids, such as slurry, sticky, easy to foam, corrosive and other media limit detection.
1. Strong adaptability - different electrical parameters and densities of the tested materials have no impact on the measurement. Harsh conditions such as scaling, agitation, turbulence, bubbles, vibration, medium viscosity, high temperature and high pressure also have no impact on the detection.
2. Maintenance free - since the detection process of tuning fork limit switch is completed by electronic circuit and there are no moving parts, maintenance is not required once it is installed and put into operation.
3. No need for adjustment - since the detection of tuning fork limit switch is not affected by the electrical parameters and density of the measured medium, no matter what liquid is measured, it does not need to be adjusted on site
