How to choose a water level sensor?

With the increase of automation, in order to ensure the consistency of product quality, the production process directly from the era of manual monitoring and intervention is far away, the importance of the sensor is more and more obvious. For example, water level sensors are used for water level control and water level detection.

Because of the complexity and variability of the detection environment of the water level sensor, but also for the application of the sensor has brought different challenges. For example: high viscosity liquid height detection, impurity-containing wastewater level monitoring, level height measurement with foam, highly corrosive liquid height alarm and so on. Currently for different applications, provides a variety of effective solutions, but how to choose the right, cost-effective sensors has been a headache for consumers.

Aiming at the above different problems, as well as the use of different environments, different applications, can point of science and technology to turn to the different needs of the market and design a different water level sensor, for different user needs can provide a variety of effective solutions.

Photoelectric water level sensor introduction:

Photoelectric water level sensor is now one of the market's most widely used water level sensors, photoelectric water level sensor is a sensor used to measure changes in the position of the liquid.

Photoelectric water level sensor measurement principle: the use of light in two different media surface reflection and refraction characteristics, through the reception of reflected and refracted light angle and intensity to respond to changes in liquid level.

With the coffee machine as an example, a simple explanation of the principle of the photoelectric level sensor we can point technology

Principle is to install the photoelectric level switch in the bottom of the coffee machine container, when the water level falls to a low level, the photoelectric level switch will give a signal prompting the lack of water state, so that the device stops working, it will automatically enter the state of the water; mounted on the side, when the water to a certain position, the photoelectric level switch will give a signal prompting the lack of water state, thus the device stops working, it will automatically enter the state of the water; installed in the side, when adding water to the certain When installed on the side, when the water is added to a certain position, the photoelectric level switch will also give a signal, so that the equipment stops adding water to prevent the water from overflowing.

Integrated photoelectric water level sensor

Applied to other electrical appliances as well, there is the function of detecting the water level, which can prevent the machine from being burned out when the water is too low, and also prevent the water from overflowing out of the container, which can lead to other accidents.

Nengdeng Technology's photoelectric water level sensors are available in a variety of styles, depending on the purpose of the different styles chosen. Each water level sensor is small in size, simple in structure, simple in installation, upward, downward, sideways, diagonal installation;

High detection accuracy, no mechanical parts, no debugging, high sensitivity, corrosion-resistant, low power consumption, low price, and so on, and so on, and so forth.

Such as photoelectric water level sensors are mainly used in the following areas:

l, humidifiers, water heaters, water dispensers, automatic milk dispensers

2, printers, printer, inkjet printer, coffee maker, steam microwave ovens

3, pumps, bathtubs, toilets, humidifiers, sanitary wares, medical equipment

4, other electrical appliances that require liquid level control,

The advantage of capacitance type is that it can realize the direct detection without contacting the liquid, the water tank does not need to open the hole, and there are impurities, dirt, sediment, etc. in the water tank container will not affect the results of water level detection.

Capacitive more used in water dispensers, coffee machines, printers, water floaters, water floaters, bathtubs, sanitary ware, medical equipment, and other appliances and equipment that need to be used to control the liquid level.

EPT capacitive water level sensor

If you need to detect more than one liquid level, you need to use multi-point water level sensor, our multi-point water level sensor can realize the detection of 2~6 liquid level points.

Separate water level sensor in the circuit setup is relatively simple, only the signal into the MCU analog-to-digital converter port, the data can be analyzed to achieve higher detection accuracy.

Infrared level sensors can measure the level of liquid from the bottom of the tank 1 MM level, and ultrasonic level sensors due to its first launch and then receive the principle, due to the time difference, ultra-close range can not be detected.

The above are the recommended water level sensors according to different applications without using the environment. Of course, this is only a recommendation, the most appropriate program is best recommended by the company's sales staff has been optimistic about the product, after all, familiar with the product will recommend the appropriate program.
