RF capacitance level switch

Technical Parameter

Product Introduction:

rf capacitance level switch is a new generation of intelligent continuous material level measuring instrument. Due to the use of radio frequency detection technology and modern microcomputer processing technology, the problems of traditional liquid level gauges such as large temperature drift, difficulty in calibration, and fear of adhesion are solved. It is widely used in various industries for continuous measurement of liquid, granular and block material levels. The special impact-resistant and wear-resistant probe rod sheath material used by rf capacitance level switch is the first of its kind at home and abroad. Admittance level gauge is particularly suitable for measurement in environments such as high temperature, high pressure, strong corrosion, strong adhesion, strong impact, strong wear, and high dust. It has a cost-effectiveness that other types of liquid level gauges cannot match.

The equipment consists of sensors and control instruments. The sensors can be installed on the top of the warehouse using rod, coaxial or cable probes.

The pulse card in the sensor can convert changes in material level into pulse signals and send them to the control instrument. After calculation and processing by the control instrument, it is converted into engineering quantities and displayed, thereby achieving continuous measurement of material level. Due to the use of radio frequency admittance detection technology, reliability has been improved and installation and debugging have become very simple.

Working principle

The working principle of the RF capacitance level switch is based on the change of capacitance. During the measurement process, the probe of the liquid level switch (usually made of metal) comes into contact with the liquid or material in the container, forming a capacitance. When the liquid level changes, the capacitance value changes accordingly. The liquid level switch detects changes in capacitance value to determine whether the liquid level has reached a set threshold, thereby sending out a switch signal to monitor and control the liquid level.

Radio frequency capacitive liquid level switch is suitable for the following places:

1. Petrochemical industry: used to monitor liquid levels in storage tanks, reactors and other equipment, such as petroleum, chemical raw materials, acids, alkali, etc.

2. Environmental protection field: used to monitor the sewage level in sewage treatment plants and wastewater treatment equipment.

3. Electric power industry: used to monitor liquid levels, such as water, steam, etc., in boilers, pressure vessels and other equipment.

4. Papermaking industry: used to monitor the liquid level of slurry, pulp and other materials.

5. Pharmaceutical industry: used to monitor the level of various liquids and materials in the pharmaceutical process, such as pharmaceuticals, solvents, etc.

6. Hydraulic machinery field: used to monitor the liquid level of lubricating oil, hydraulic oil, etc. in hydraulic equipment.

7. Grain department: used to monitor the liquid level of edible oil, grain, etc. in grain warehouses.

8. Oil field: used to monitor the liquid level of crude oil, refined oil, etc. in oil fields.

RF capacitance level switch have the advantages of high measurement accuracy, good stability, and easy installation. They are widely used in liquid level detection and control in various industries.

Product Features

4-20mA/RS-485 multiple signal outputs, convenient for users to choose according to different system configurations.

The rf capacitance level switch is widely used in liquid level measurement of high-temperature and high-pressure vessels. Its measured value is not affected by the temperature, specific gravity, shape and pressure of the liquid being measured. In addition, the level gauge also has complete over-current, over-voltage protection functions and power supply polarity protection to ensure stable operation of the equipment in various complex environments.

Anti-adhesion function: Using advanced anti-adhesion circuit design, it can effectively avoid false error signals caused by material adhesion and improve measurement accuracy.

Strong adaptability: It can detect solid and liquid materials in complex environments such as high temperature, high pressure, large dust, high viscosity, etc., and is not affected by the dielectric constant of the measured medium, and has extremely strong adaptability.

One-click calibration: Thanks to digital circuit technology, users only need to perform a calibration operation in a short position to easily complete the calibration process.

The equipment is easy to install and debug: it adopts a fully sealed integrated installation structure with no mechanical moving parts, high reliability and basically maintenance-free. Once installed, there is no need for multiple debugging, which greatly simplifies the installation and debugging process.
