Capacitive level sensors, ultrasonic level sensors, and discrete photoelectric level sensors. The common development of these three non-touch liquid level sensors is that they are not affected by the color, corrosiveness, pressure, density, etc. of the liquid, because these sensor skills cannot directly lead to contact with the liquid, so they are more hygienic, and the container requires data cleaning, liquid filling, etc.
The three non-touch level sensors are characterized by the fact that they are not affected by the color, corrosivity, pressure, density, etc. of the liquid, and because the sensor does not directly touch the liquid, it is more hygienic for the user to clean and add containers.
Ultrasonic level sensors detect the liquid level based on the principle of acoustic reflection. The biggest benefit is its ability to detect changes in the liquid level in real time, which is not possible with the other two non-touch level sensors. Because the sensor converts the water level into data, the user is able to know exactly how much water is remaining in real time. The ultrasonic level sensor has an accuracy of up to ±2mm, which is highly accurate and can detect the liquid level very accurately.
The non-contact level sensor is glued to the container to detect the liquid level, so the installation process is simple. Capacitive level sensors are mainly used in household appliances due to their small size and low price. If the capacitive level sensor is installed on the valve body, the container can be moved at will. For example, capacitive level sensors detect low levels in aromatherapy machines. When the sensor detects that there is only 20 ml of fragrance left in the bottle of the diffuser, it announces a signal prompt. After the device receives the signal, turn on the buzzer to alarm or light up the prompt. The user is then able to remove the bottle to add the liquid, perhaps simply replacing another bottle with a new one.
The detached photoelectric liquid level sensor has the characteristics of all optoelectronic devices, high temperature resistance, high pressure, corrosion, high level control accuracy, and can control the liquid level within ±1mm. The discrete level sensor is also treated with a resin sealant and has no moving parts inside for high reliability.
What are the different types of non-touch level sensors and how do they work? Due to its small size, high accuracy and high reliability, the discrete photoelectric level sensor is also widely used in household appliances and medical occupations. The detached photoelectric level sensor also enables the container to move freely. Compared with capacitive level sensors, discrete photoelectric level sensors have higher accuracy and reliability. The detached photoelectric level sensor uses the principle of light reflection to detect the liquid level, which has less impact on the liquid to be measured and is more hygienic. The key is that the sensor can be installed up, down, sideways, and obliquely, and the installation process is simple.
