For this type of shared beverage vending machine, the merchant will install a level switch on the machine. When the vending machine's beverage reaches a certain limit height, it is necessary to stop filling the container with water, otherwise it will cause spillage, which may cause leakage, and in heavy cases, the internal circuit of the machine may be short-circuited by water and fire or explosion. However, when the beverage is lowered to a certain level, it is also necessary to detect the condition of the liquid level through a sensor at this time, so that the heating device is stopped, so as to avoid dry burning and unnecessary losses.
However, due to the need for direct contact with drinks, the specific material of the sensor also has strict requirements. The most important thing is that it can be in contact with food and is non-toxic and harmless. We recommend FS-IR02 with CE & ROHS level sensor. This model level sensor meets food grade required.
FS-IR02 liquid level sensor 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. As long as two water level switches or a multi-point photoelectric liquid level sensor are installed on the water tank of the shared vending machine, the amount of liquid in the container can be detected at any time, and the start and stop of the relevant components of the machine can be determined according to actual needs.
