Below is a list of Atmospheric Pressure Sensors manufacturers from San Marcos, Texas. Atmospheric pressure sensors, also known as air pressure sensors in some contexts, measure the force exerted by the weight of air and convert the information from electrical energy to a readable display. Sensors take the energy from the force of the pressure and change it into a comprehensible form that can be read from a gauge or display. Sensors are used extensively in meteorology to help identify weather patterns and predict upcoming storms. Scientists use atmospheric pressure sensors during research and experiments because substances behave differently when under pressure.
