Photoelectric liquid level switch is a kind of switch device which uses photoelectric sensor to control the switch so as to control the liquid level.
Principle of photoelectric liquid level switch
Photoelectric liquid level switch uses infrared detection, using the principle of refraction and reflection of light, light in two different media interface will produce reflection or refraction phenomenon. air
Application environment of photoelectric liquid level switch
environment Even within the range of service temperature, if there is a sharp temperature rise and fall, it will shorten its life, so it should be noted.
