Even if you don't know anything at all about pressure sensors, it is fairly obvious from their name that these are devices used for measuring pressure. They are used to measure the pressure of gases and liquids in thousands of applications and environments, from homes to industrial and commercial environments.
There are many different types of pressure sensors currently available, and each varies in aspects such as design, performance, cost, the technology used and the applications it can be put to. It can be useful to know a little about each type of pressure sensor, especially if you intend to use or buy one at some point in the future.
First on the list of pressure sensors you should know about is the absolute pressure sensor. This is specially designed to measure pressure according to something commonly known as perfect vacuum pressure.
Another type, a gauge pressure sensor, is used for many different applications. This is because you can calibrate it in order to measure pressure relative to the atmospheric pressure in any location. A common example of this type of pressure sensor is found in car tyres.
Similar to the gauge pressure sensor is the sealed pressure sensor, which only differs in that the manufacturer ensures it is calibrated so as to measure pressure in relation to sea level pressure. Vacuum pressure sensors, on the other hand, are used to measure pressure that is less than the atmospheric pressure in a given location.
Last of all, there is the differential pressure sensor. Designed to measure and compare the difference between two or more different pressures, these sensors are commonly used in oil filters, to measure drops in pressure, or to measure the flow or level in pressurised vehicles.
