Pressure sensors detect pressure (such as atmospheric, liquid, or gas pressure) and convert it into an electrical signal. Pressure sensors are used in a variety of applications including automotive, aerospace, robotics and consumer electronics. They measure pressure in the form of pressure changes, such as a change in atmospheric pressure due to the weather. Pressure sensors are also used to measure the pressure of fluids in pipes, tanks and other containers. Pressure sensors can be used to measure everything from a car's speed to the air pressure inside a medical tubing. They can be used to monitor pressure levels in a variety of applications, including medical, industrial and consumer.
