Barometric pressure transducers work to convert presure into an electric signal. Digital Barometers measure and display atmospheric pressure.
There are many uses for a digital barometer. They can be used with aircrafts to measure altitude and air pressure, measure air speed at construction sites to ensure worker safety and in marine applications to measure barometic pressure when navigating ships. Digital barometers can even be used in sports such as mountaineering and sailing to measure barometric pressure for safety reasons.
