The tuning fork switch is a level control instrument based on the principle of vibration. It is mainly used to detect the level of solid materials (such as powder, granular, etc.) or the level of liquids. It works by detecting the presence or absence of material through the vibration of a resonant fork (usually made of metal). When the fork of the tuning fork switch is covered with material, its vibration frequency will change, and this change will be converted into a signal to indicate the presence of the material.
Types of tuning fork switch
Solid material tuning fork switch
The solid material tuning fork switch is designed to be dust-proof and anti-corrosion, and is suitable for material level monitoring under various complex working conditions. Its installation is usually relatively simple and can be fixed on the silo or container through flanges, threads, etc. The detection of tuning fork switches for solid materials is not affected by the physical and chemical properties of the materials, so it has a wide range of applications.
Typical Application:
Used to detect the level of chemical fertilizers, plastic particles, PVC powder, mineral powder, coal, flour, sugar, coffee beans, pharmaceutical powder, cement powder and other building materials.
Liquid tuning fork switch
The liquid tuning fork switch is a liquid level measuring instrument that detects liquid level based on the principle of vibration. When the fork body of the tuning fork switch is inserted into the liquid, the viscosity and density of the liquid will affect the vibration frequency of the fork body, and this change will be detected The circuit captures and converts the switching signal to obtain the liquid level.
Typical application:
Mainly used for monitoring the liquid level of water tanks, oil tanks, chemical storage tanks, etc., liquid level control in industrial production processes, pump control, and liquid level measurement in pipelines.
High temperature tuning fork switch
High-temperature tuning fork switch is a liquid-level measuring instrument specially designed for high-temperature environments. Ordinary tuning fork switches are generally suitable for lower-temperature environments, while high-temperature tuning fork switches can withstand higher temperatures.
Typical Application:
Mainly used in high-temperature operations in various industries, such as chemical and petrochemical, pulp and papermaking, thermal power generation, metallurgy, high-temperature sterilization of food and beverages, etc., all require the use of high-temperature tuning fork switches.
Advantages of tuning fork switch
Simple and reliable
The structure of the tuning fork level switch is relatively simple, mainly composed of a tuning fork and an electronic circuit. It does not require complex adjustment and maintenance and has high reliability.
Strong adaptability
The tuning fork level switch can be used in a variety of situations, including corrosive, high viscosity, easy to crystallize, high pressure, high temperature, and other working conditions, and is suitable for the detection of a variety of liquid and solid materials.
Good anti-interference performance
The tuning fork switch has strong anti-interference ability against vibrations, pressure changes, temperature fluctuations in the external environment, etc., and can ensure measurement accuracy.
Easy to install
Tuning fork-level switches are usually installed with threaded connections or flanges. They are easy to install and are not restricted by the installation direction. They can be installed vertically, horizontally, or at any angle.
Low maintenance
Tuning fork-level switches generally do not require regular calibration. Only regular cleaning of attachments on the tuning fork can ensure its normal operation, reducing maintenance costs.
Safety and environmental protection
The tuning fork level switch does not use radioactive substances or magnetic materials, is safe and harmless to the human body and the environment, and meets environmental protection requirements.
Application of tuning fork switch
water tank, storage tank
When the tuning fork level switch is used in water tanks, it is mainly used to monitor and control the liquid level or material level. When the liquid level in the water tank storage tank reaches a preset threshold, the tuning fork level switch will send out an alarm signal to remind the operator or the control system that the liquid level has reached the limit value. It is also used to monitor material levels to prevent materials from accumulating too high or too low and ensure the stability of the production process.
Fertilizer production
In the process of chemical fertilizer production, a large amount of raw materials and finished products need to be stored, such as urea, phosphate, potash fertilizer, etc. The tuning fork switch can be installed on the silo to monitor the material level of raw materials or finished products to ensure the smooth progress of the production plan while avoiding production interruption or material spillage due to too high or too low material levels.
Food production
The tuning fork level switch can be used to monitor the level of dry granular or powdery materials such as grain, sugar, flour, etc. in raw material warehouses to ensure a continuous supply of the production line and avoid excess or shortage. It can also be used to monitor liquids such as water, oil, syrup, etc. tank levels, which is critical to maintaining a stable production flow. During the food packaging filling process, the tuning fork level switch can ensure the correct filling amount of the product in the packaging container, thereby improving packaging efficiency and reducing waste.
Paper industry
During the pulping process in paper mills, tuning fork level switches are used to monitor the liquid level in slurry pools or storage tanks to ensure that the slurry supply is stable and not full. It can also be used to control the thickness of paper coatings and monitor water levels in freshwater or wastewater treatment tanks to optimize water use and comply with environmental regulations.
Capacitive level switch
detects material height by measuring changes in capacitance. When the probe comes into contact with the material, the capacitance will change, triggering the switch action.
Tuning fork level switch
Using the principle of tuning fork vibration, when the material contacts the tuning fork, the vibration frequency will change, thus triggering the switch action.
Ultrasonic level switch
Use the time of ultrasonic wave propagation in the medium to measure the distance to determine the height of the material. When the ultrasonic wave emitted by the probe encounters the material and is reflected back, the height of the material is calculated based on the time difference between receiving the echo.
Laser level switch
uses a laser beam to measure material height. When the laser beam is blocked by material, the receiver detects this change and triggers a switch action.
Infrared level switch
Similar to the laser type, it uses infrared rays to detect the height of the material. When the infrared ray is blocked by the material, the sensor will detect the signal change and trigger the switch action.
Guided wave radar level switch
uses guided wave radar technology (such as single or dual cable) to measure the height of materials. The probe sends microwave pulses, which propagate along the probe and reflect back off the material surface. The propagation time is measured to determine the material level.
Servo motor level switch
Use a servo motor to drive a float that can move up and down to measure the liquid level. When the liquid level reaches the set point, the float triggers the switch action through the mechanical linkage.
Vibrating rod level switch
similar to the tuning fork type, but uses a vibrating rod as the detection element. When the material comes into contact with the vibrator, the vibration mode of the vibrator changes, triggering the switch action.
