Pressure and Water Safety

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure and Water Safety

“Not (intended as) a life saving device” is commonly found on inflatable products that can be used in a pool, river, lake and even the ocean.  With the summer of 2019 well under way, most inflatables have already been pressurized so they can float and support the weight of even the heaviest person. However, when a new float is purchased or one found that wasn’t inflated, the user has the choice of using a pump or their lungs to add the necessary quantity of air. If a pump is not an option, the amount of air that must be blown into the device can be an issue, especially for a large float or for a person with limited lung capacity. For a large float, it could take a lot of time for the cumulative exhales to inflate it.

While it gets obvious when the float is near its limits, pressure is also an issue. Buoyancy or buoyant force is created by the difference between the pressure at the bottom of the float pushing it up and the pressure at the top pushing down. Archimedes principle and actual pressure measurements for flow and internal pressure could be brought into this discussion but it’s time to just relax and float around.
