The working principle of Hot Water Optical Level Sensor is direct and simple. When the detected level is in air, due to reflect of the prism, most of light will enter receiver LED, optical level sensor will output high voltage.
When the detected level is in water, due to refraction of the liquid, just less of light enter receiver LED, optical level sensor will output low voltage.
Optical level sensor is widely used in level control and alarm of all kinds of industry such as electronic, electric power, chemical, water treatment, water supply due to its low price, reliable performance and flexible installation method.
Products comply with RoHS food grade requirements of environmental protection. We accept OEM.
