Pressure Sensors
A pressure sensor is a device which senses pressure and converts it into an analog electric signal whose magnitude depends upon the pressure applied. Pressure is defined as force per unit area that a fluid exerts on its surrounding. Since they convert pressure into an electrical signal, they are also termed as pressure transducers.
Absolute pressure is measured relative to a perfect vacuum, atmospheric pressure is an example. A common unit of measurement is pounds per square inch absolute (psia). Differential pressure is the difference in pressure between two points of measurement. This is commonly measured in units of pounds per square inch differential (psid). Gauge pressure is measured relative to ambient pressure, blood pressure is one example. Common measurement units are pressure per square inch gauge (psig).
The SI unit for pressure is the Pascal (N/m2), but other common units of pressure include pounds per square inch (PSI), atmospheres (atm), bars, inches of mercury (in Hg), and millimetres of mercury (mm Hg).
Pressure sensors have been widely used in fields like automobile, manufacturing, aviation, bio medical measurements, air conditioning, hydraulic measurements etc. In automotive industry, pressure sensors form an integral part of the engine and its safety. In the engine these sensors monitor the oil and coolant pressure and regulate the power that the engine should deliver to achieve suitable speeds whenever accelerator is pressed or the brakes are applied to the car. In instruments like digital blood pressure monitors and ventilators, pressure sensors are needed to optimize them according to patient’s health and his requirements.
