In its most basic form, pressure is defined as the amount of force being applied to an area. As this force is distributed over a specific area, a change in movement of the defined area is occurring. It is important to remember that a force is just an occurrence that is causing an object to move, either accelerating or decelerating. The amount of movement from that object is based upon the amount of force. Pressure is very unique in that it is not subjected to a direction, but by the force acting on an area in a perpendicular motion. Because of this action, movement by the area is created (this is sometimes referred to as a deflection). The amount of this deflection can then be measured to provide a representation of the amount of pressure being applied. As the need for this information grew, manufacturers created a device that is designed to deliver this measurement: the pressure sensor. This white paper will define pressure, identifying how it is applied and measured. The white paper will also highlight how pressure sensors affect process environments and how they are applied in specific applications.
