Product Details

Product description

FS-IR22 top mount level switch contains an infrared emission source and a detector. When the tapered end of the sensor is immersed in liquid, infrared light will be transmitted out of the tapered surface, and the intensity of the light reaching the detector will be weak, giving a signal. If you want to detect the high and low level in the water tank, you can install the two FS-IR22 level switches or a multi-point photoelectric level sensor on the water tank of the shared vending machine to detect the amount of liquid in the container and the start and stop of the related container at any time. The composition of the machine can be determined according to actual needs.
