Microwave Liquid Level(Material Level)Sensor(Switch) Introduction and Application

 Description:

The microwave material level switch determines the capacitance value at the end of the sensor and the dielectric constant value of the medium through a high-frequency electric field. because the dielectric constant value of air is different from the dielectric constant value of the medium, and two states can be identified: covered and uncovered. Under normal conditions, the indicator light is off to indicate that it is not covered, and the indicator light is always on to indicate that it is covered, and the switch is switched. This product has the characteristics of compact structure, strong resistance to material hanging, good stability, and wide application for media.

Main Parameter:

 

1. Power Supply: 12-30VDC.

2. Output Mode: NPN/PNP,PWM.

3. Logic Output: NO+NC.

4. IP Grade: IP67.

5. Materials: 316 stainless steel, PEEK probe.

6. Response Time: 0.2s

 

Features:

1. The sensor design is compact and suitable for installation in confined spaces.

2. High temperature tolerance, up to 200 degrees.

3. Wide range of applicable media, most of the liquid, slurry, pasty fluid, solid can be measured.

4. The material is resistant to hanging, the liquid has viscosity, and it is easy to hang without affecting the final measurement result.

 

Application:

1. Beer fermentation tank, measuring whether the foam produced by fermentation reaches the specified height.
2. Resin reactor, after generating foam, detect whether the foam reaches the specified height.
3. Milk tank, detect the milk filling process to see if it is overflowing.
4. In the evaporation tank during the pharmaceutical production process, the vacuum causes the medicinal liquid to boil at room temperature, thus producing a large amount of foam.
5. Vacuum toilets need to withstand the interference of toilet paper and feces for a long time.
6. Paint production tanks, detect the upper and lower limits of paint.

7. All occasions where tuning fork switches are used.
8. Paint cans for paint spraying production lines, such as: shipyards, automobile factories, and baking paint factories.
9. In the grinding production line of daily chemical companies, because most of the materials are slurry, highly viscous, and prone to bubbles and adhesion, traditional sound and radio frequency admittance switches often cause false alarms, which can easily cause the production line to operate incorrectly, such as explosion, overflow, blockage or even explosion. Microwave sensor switches can be used instead.
10. On smaller containers, if the tuning fork or radio frequency admittance switch cannot be installed due to its size, or if it is installed and cannot be detected at an effective position, a microwave induction switch can be used instead.
11. When measuring materials on pipelines, due to the limitation of the inner diameter of the pipeline, microwave liquid level switches can only be used instead for pipelines within DN100. The length of the switch that extends into the pipeline is only 1.0~2.0 cm.

12. High and low level monitoring of buffer tanks in the food industry.
13. Liquid level detection of containers containing viscous liquids such as tomato paste, honey, juice, etc. in the food industry.
14. The separation process of two different liquids in the food industry and the detection of the liquid interface.
15. Check whether there is liquid in the pipeline to avoid power consumption and damage caused by idling of the pump.
16. Detection of foam, maximum liquid level, and minimum liquid level during the fermentation process.
17. Hygienic position inspection of injection molding, filling and sealing equipment.
18. Detect the interface between oil and water, including the interface between two other liquids that do not mix and dissolve each other.

19. The beer storage tank is not affected by foam and can measure whether the beer has reached the specified height.
20. In the corn fermentation tank, after foam is measured, the system will take other measures to eliminate the foam.
21. Measure two different states of the production process, such as whether the inside of the jar is in production state or cleaning state.
22. Measure whether the sensor is foam or liquid. If it is foam, the first set of NPN signals will be output. If it is liquid, the second set of NPN signals will be output.
23. Check whether detergent remains in liquid food.
