A pressure sensor measures pressure, typically of gases or liquids. Pressure is an expression of the force required to stop a fluid from expanding and flowing and has a SI unit of force per unit area. In modern world, there are many fields where the use of pressure sensor is mandatory.
One of such fields is Semiconductor processing. This is where the pressure sensors are used to manufacture and filter artificial made water. In water treatment plants, these devices are used to maintain the liquidity of the water. One of the most important uses of pressure sensors is in thermal power plants online . In thermal power plants, the main principle of generating electricity is thermodynamics. Now, a fuel (general coal) is used to convert liquid raw water into water vapors and these steams are used to move the huge turbines. To achieve maximum efficiency, pressure sensors are placed in such a manner that they look out for the waste water and track them back to the boiler area where they can be re-used.
Now a day, sensors are used in heavy transportation vehicles also. When the transportation of huge liquid/gas container is required, the risk of accident increases due to the unstable nature of both liquid and gas. To overcome this situation, Transportation vehicles now are equipped with modern sensor technology. The main function of this technology is to monitor the pressure of fluid and indicate the data to the driver. Since the data is monitored by the driver itself, the risk becomes minimum as the driver can adjust his driving whenever required.
Robotics is also a great example where pressure sensors are used. As we all know that the artificial intelligence is yet to achieve its maximum feat and till then, automatic equipment has to rely on pressure gadgets to walk and do what they are supposed to do. Pressure sensors record every move the equipment makes and then transfer the data back to the developer for ramifications and modifications as required.
In the industries of refrigeration, sensors play a very important role in making sure that the stuffs stays refrigerated. Compressors and Lube Oil Pressure Equipment are the typical sensors for refrigeration. What compressor does is it compresses the oxygen into its molecular state by using heavy pressure and when it is converted; it has a tendency to absorb heat from the surrounding and act as a coolant.
