Photoelectric level sensors are a new type of contact-type point level measurement and control device developed based on the principle of light reflection and refraction at the interface of two different media. Since the liquid level output depends only on whether the photoelectric probe is in contact with the liquid surface, and is independent of other characteristics of the medium, such as temperature, pressure, density, and electrical parameters, photoelectric level sensors have many advantages, including simple structure, high positioning accuracy, no mechanical parts, accurate detection, high repeatability, fast response speed, corrosion resistance, low power consumption, very precise liquid level control, and direct installation and use without calibration. These advantages have led to their increasing market acceptance. Next, the editor of ICbuy.com will discuss the installation and application of photoelectric level sensors.
Installation and liquid level control
Photoelectric liquid level sensors are versatile sensors that can be installed in various positions, including top, bottom, side, and angled. However, the key differences in installation methods lie in whether screws or nuts are used for fixing, and whether the installation proceeds from the inside out or the outside in from within the water tank.
Install the liquid level sensor in one of the above methods, and then connect it in the following circuit. The signal terminal will output a voltage signal that is consistent with the water level. When the liquid level exceeds the critical level and submerges the sensor body, the signal output is low voltage. When the liquid level is below the critical level and exposes the sensor body, the signal output is high voltage.
application:
Photoelectric liquid level sensors can be divided into three categories according to different applications: separate type, integrated type, and photoelectric type.
Integrated: Used in equipment where the water tank/container is not separated from the machine.
Separable type: Applied to equipment where the water tank/container can be separated from the machine.
Multi-point type: used for simultaneous detection of multiple liquid points
It's worth noting that the size of photoelectric liquid level sensors varies depending on the application environment. For appliances like water heaters and coffee machines, size is generally not a concern. However, for machines like printers and facial sprayers, the size of the sensor needs to be considered.
