Pressure sensors have a variety of applications and can be used to measure the pressure in industrial procedures. They are used for aeronautics, weather studies and in automobiles etc. All kinds of industrial machines and equipment involved with pressure based tasks have pressure sensors in their applications.
What are the applications?
Pressure sensors are used in hydraulics, pneumatic systems, measuring submarine depths, water depths, liquid and gas pressures, etc. Pressure sensors can measure extremely minute pressures and hence have found very wide application in all kinds of industrial processes.
What are some of the specific uses of pressure sensors?
Pressure sensors that are made for high altitudes work with the Venturi effect for pressure measurement. The difference in pressure between two segments of a Venturi tube is measured by differently calibrated apertures. This difference is calculated to arrive at pressure levels. The speed of gas flow through the tube is directly in proportion to the differential pressure. A low range pressure sensor would be required if the difference in pressure is only small.
The common types of pressure sensor
There are almost unlimited varieties of pressure sensors according to their specifications, purposes, applications and uses. The commonly used pressure sensors which measure all ranges of pressures are expensive but highly accurate and efficient. Pressure sensors are manufactured specifically for measurements of pressures in very high temperatures and with field adjustments etc. Ceramic pressure sensor capsules, depth transmission pressure sensors, gauge pressure sensors, absolute and differential pressure sensors are some of the most common types.
Pressure sensors play a very important role in ensuring industrial safety and production standards by sounding timely alarms when the pressure in any industrial process is deemed to be inappropriate.
