Sensor taps, also known as automatic taps, turn the flow of water on and off independently, using a sensor to determine when a person’s hands are held under it. They are most often found in public bathrooms, but can be useful in the home as well, especially for the disabled or elderly who may have trouble turning a regular tap on and off.
How it Works?
A sensor tap isn’t a very complex piece of technology. Through the use of an infrared light sensor, the faucet can “see” when hands are in proximity. The sensor then triggers a solenoid valve, which is closed most of the time, and opens only when triggered. When the valve is open, water flows out: either until it sense that the hands have been removed, or for a predetermined number of seconds, measured by the timer. Most sensor taps are battery powered.
Why Public Bathrooms Need Sensor Taps?
Automatic taps do so much for public bathrooms. High traffic bathrooms may see dozens or even hundreds of people passing through each day, and a sensor version offers a big hygiene advantage. When you can wash your hands without first touching the faucet, a major potential contamination area is removed, and the chances of spreading harmful bacteria are greatly reduced. A good sensor tap can also significantly cut down on water usage per use, which adds up to large savings on water and electricity bills. These can also save you from an overflowing sink. Whether it’s an accident or vandalism, a clogged sink and running tap can quickly cause major flooding and water damage. Automatic taps will shut themselves off long before the sink overflows.
How to Select The Right One?
No-touch taps come in a wide range of shapes and sizes though they all share the same basic functionality. Choosing sensor taps for your home or business will largely be a question of personal taste and budget. The style tends toward modern and minimalist, which suits many corporate environments. You’ll need to decide whether you want your automatic taps to run on mains or battery power, and choose one that is compatible with your high or low-pressure water system.
