Pressure Sensors – Type and Technologies Used in Production
Pressure sensors are industrial products that are typically used in order to measure gas and liquid pressures. It acts as if it is a transducer or a device that converts energy into another form. It is capable of signal generation by way of using the pressure imposed on optical, auditory, electrical and visual signals. air conditioner pressure transmitter
These products are considered relevant to daily living. In some instances, they are also called as transmitters, indicators or senders. Variables such as fluid flow, gas flow, water level, speed and altitude may also be measured through the aid of pressure sensors.
The different types of the product vary depending on the application where it is used, the cost of the product itself and the type of technology employed. They also cover measurements of pressure combustion. Here are some of the types of sensors classified according to type of pressure as well as the various technologies employed.
Types of sensors according to pressure measurements
There are actually five types of pressure sensors in this category. The first one is known as the absolute pressure sensor or one that takes sensor measurements according to perfect vacuum pressure. The second one is known as the gauge pressure sensor known to be usable in various applications because of its capability to be calibrated to adapt to atmospheric pressures in different locations. anti corrosion pressure transmitter
A third type known as the vacuum pressure sensor is one that is more popularly known in measuring pressure that is less than a certain location’s atmospheric pressure.
There are two more types of sensors namely the differential pressure sensor and the sealed pressure sensor. The former is used to obtain pressurized flow in vessels as well as to gauge whether there is a drop or increase in two or more pressure systems. The latter on the other hand, is used in order to calculate sea level pressure.
Technologies that make up these industrial products
There are also various technologies adapted to come up with a pressure sensor. Fiber optic sensors are those that obviously make use of the concepts of fiber optics. The sensor then becomes a product of small pieces of fiber optic interferometers. food and beverage pressure transmitter
Mechanical deflection is also used in order to produce a pressure sensor. A liquid’s mechanical properties are often measured to derive the pressure and to check on its effect on a spring system. Any spring compression changes are also recorded to come up with the ample measurement of the pressure.
Other technologies that make up pressure sensors are strain gauge, semiconductor piezoresistive, microelectromechanical systems, vibrating elements and vibrating capacitance. Each of these technologies has its own distinct characteristics.
Overall, a pressure sensor is useful in aircraft, cars and other machinery pressures as well as weather instrumentation, weather balloons, rockets and satellites.
