What is a tuning fork level switch? What does it do?

Tuning fork. The liquid level switch is a new type of liquid level switch. The tuning fork is excited by the crystal to produce vibrations, and when the tuning fork is immersed in liquid, the vibration frequency changes, and this frequency change is detected by the electronic circuit and outputs a switching quantity.

Measurable: solids, liquids, powders and other particles that are not easy to jam, acid and alkali dyes.

Solution, slurry, wastewater, flour, beer, beverages, glue, pulp, sewage with impurities and hydrochloric acid, sodium hydroxide.

greases, lubricating oils and other industrial fluids;

The tuning fork switch is suitable for almost all liquid media, and the tuning fork switch is not affected by foam, vortex, gas. At the same time, it is also suitable for measuring medium-density solid powder or granular tuning fork switches that can flow freely, and can measure a variety of levels, with high and low fail-safe limit switches.

Overflow or dry run protection, pump control, show whether there is flow in the pipe, etc.

Tuning fork switches are mainly used in challenging liquids, including sewage with knots and impurities, and industrial liquids such as hydrochloric acid and sodium hydroxide.

Tuning fork level switch is also often called tuning fork level meter or tuning fork level controller, mainly because the tuning fork level meter appears in different links in industrial production, and the key role it actually plays is different, so people habitually call out many different names. Tuning fork level switch is a kind of level switch, mainly using the principle of tuning fork resonance to measure the level state, its unique fork design and its inherent vibration characteristics, can ensure the automatic removal function of the tuning fork and prevent hanging material to the greatest extent. The tuning fork level switch is a new type of level control switch, which mainly relies on the tuning fork to measure the level height through the vibration principle.

The working principle of the tuning fork level controller is to vibrate the tuning fork at a certain resonant frequency by a pair of piezoelectric crystals mounted on the base of the tuning fork. When the tuning fork comes into contact with the medium to be measured, the frequency and amplitude of the tuning fork change, and these changes are detected, processed, and converted into a switching signal by intelligent circuitry. Applications of Tuning Fork Level Switches:

1.Slurry, viscous, foamy or corrosive liquids.

1.Medium-density solid powders or granules that flow freely. For example, fly ash, cement, sand, stone powder, plastic particles, salt, sugar, etc.

2.Liquids with ** and non-** hazards, corrosive liquids (acids, alkalis) and high viscosity liquids. Such as, water, acid, alkali, mud, pulp, dyes, oil, milk, wine, beverages, etc.

3.Toxic substances.

Tuning fork level switch product features:

1.Strong adaptability: the different electrical parameters and densities of the measured liquid have no effect on the measurement.

Harsh conditions such as scaling, agitation, turbulence, bubbles, vibration, medium viscosity, high temperature, and high pressure also have no effect on the inspection. 2.Maintenance-free:

Since the detection process of the tuning fork limit switch is completed by electronic circuits and has no moving parts, it does not require maintenance once it is installed and put into operation. 3.No tuning required:

Since the detection of the tuning fork limit switch is not affected by the electrical parameters and density of the medium to be measured, no matter what kind of liquid is measured, no on-site adjustment is required. 3. Typical application of tuning fork level switch 4Tap water, mineral water, pulp, glue, dyes.

5.Slurry, alkali solution, acid solution. 6.

Beer, beverages, liquids that produce gases. 7.Solid powder with good fluidity.

The tuning fork level switch is caused by the resonance of the transistor, when the material is damped, the amplitude decreases sharply and the frequency and phase change significantly, these changes will be detected by the internal electronic circuit, after processing, converted into a switch signal output. So what are the characteristics and scope of application of the tuning fork level switch? The tuning fork level switch has the characteristics of strong anti-interference, simple installation and maintenance-free, which can monitor, control and alarm the high and low positions of the tank, and is suitable for fixed-point alarm or control of various liquids, powders, granules, various silo levels and liquid levels in various containers.

The tuning fork level switch is not affected by foam, vortex and gas, and is suitable for all high-viscosity liquid media with ** and non-** dangerous liquids, corrosive liquids; Everyone has latent energy, it's just easy: obscured by habit, lost by time, consumed by inertia. It is also suitable for measuring lightweight, solid powders or granules that can flow freely.

The tuning fork level switch can measure a variety of objects, with high and low fail-safe limit switches, overflow or dry running protection, pump control, display of fluid in the pipeline and other functions.

The principle of the tuning fork switch is to sense the part of the material according to the vibration of the insert, when the material arrives at the body, the vibration frequency of the body will change, so the height of the level can be determined.

The working principle of the tuning fork level switch is to make the tuning fork vibrate at a certain resonant frequency by a pair of piezoelectric crystals mounted on the base of the tuning fork. When the tuning fork of the tuning fork is in contact with the medium being measured, the frequency and amplitude of the tuning fork will change, and these changes will be detected, processed and converted into a switching signal by an intelligent circuit.

The advantages of the tuning fork level switch are greater than the disadvantages, first of all, let's talk about the advantages of the tuning fork level switch, I believe that the friends who have used it all understand that the tuning fork level switch is used in the field during the use of the field, its stability is good, and basically it does not need maintenance, so in the process of level measurement, the tuning fork level switch is widely used.

Tuning fork switch: It is a kind of switch, which outputs the switching signal, which is the switching amount 0 and 1; It is a measurement of the opening and closing momentum of the relay switch;

Tuning fork type level switch, due to the adjustable amplitude, is convenient for measuring materials of different states and densities, and is suitable for fixed-point detection, alarm or control of solid material level in various silos and liquid level in various containers.

The medium that can be measured can be roughly summarized as:

A tuning fork switch is a kind of output switching instrument, usually used with a level meter, usually composed of three parts, a fork body, a conversion circuit board, and a meter head.

In fact, compared with the domestic tuning fork level switch, there is no advantage at present, the only advantage can only be said to be its **, an imported tuning fork level switch is enough to choose the domestic 2-3, why such a high cost and so many people use it, I believe that it only has a psychological effect.
