The development of modern technologies eliminates the need to even untwist the tap if we want to wash our hands. Water itself begins to flow, it is worthwhile to bring them to the tap above the sink . Once we would consider it a magic, but today there is not much to be surprised by such a mixer.
How does the touch mixer work?
Sensory (automatic) basin mixers from Grohe, FRAP, Kopfgescheit and others, are operated by simply placing their hands on the faucet. They have an induction sensor built in, which creates an induction field, and when it hits the hands, it (the sensor) records the change in the field and sends a signal to the electronic control unit, forcing it to open the valve and allow the water to escape, and when the induction field is normalized, close it and stop the flow.
The main role in the touch-sensitive non-contact mixer is played by the solenoid valve. And such cranes from batteries or from a network through a transformer are fed, sometimes there are combinations of these two options.
Due to the fact that the sensor mixer is equipped with a thermostat, you do not need to adjust the water temperature every time. You once set a comfortable temperature with a lever or a valve and use the faucet, without mixing the cold and hot water each time.
Advantages of sensor mixers for sinks
Such devices are ideal for public places where people often use water, unscrew and twist the cranes, because of what they quickly fail. With a touch mixer this will not happen. Batteries will last for long even with intensive use.
Another advantage is that you do not need to touch the valves to open the water. This frees you from contact with a lot of bacteria left by other people.
For forgetful people, the touchscreen will also serve as an economical device, because the water will stop as soon as you move away from the sink, and the meter does not count the huge flow of water.
