What is a true level switch?

The liquid level switch can provide very accurate and reliable liquid level detection. The principle is based on the principle of light reflection and refraction. When there is no liquid, the light reflects the front surface of the prism or the sphere; the liquid covers the sphere of the photodetector, and the light is refracted, so that the output changes. - Corresponding transistor or relay action and a switch output.
Apply this principle to make a single or multi-point level switch.
Features:
1. Accuracy of liquid level detection, high repeatability and rapid response.
Whether the output of the liquid level switch and the photodetector only contact the surface (body), the media and other properties (temperature, pressure, density, electrical parameters) are irrelevant, so the liquid level detection accuracy and repeatability are high;
Due to the response speed and liquid level control, it can be very **.
2, can be more liquid level switch
Because of the relatively small size, the photodetector on the measuring rod can be equipped with multiple photodetectors and more liquid level switches.
3, high reliability, long life, free maintenance
Since all components inside the measuring rod are packaged and processed, there are no moving parts inside the sensor, so the sensor has high reliability, long service life and free maintenance.
4, free debugging, free calibration, installation can be directly applied
Since the liquid level signal output is only in contact with the liquid or not, it is independent of other factors, so it does not need to be installed and can be used directly.
5. Ability to adapt to the environment
Vacuum, pressure environment, flammable and explosive occasions, and special liquid environment, such as turbulent flow, bubbles, vibration, steam, Y GK series liquid level switch can be adapted.
6, adapt to the special container liquid level switch installation
Ultra-small, photodetectors can be mounted separately in a narrow space for special tanks or boats.
