Pressure measurement is the measurement of a force applied by a fluid on a surface and is usually expressed as a force per unit of surface area.​
Industrial pressure is measured using instruments that translate pressure into measurable mechanical or electrical outputs. Some common instruments used to measure industrial pressure include switches, pressure gauges, pressure transducers and pressure transmitters.​
There are many considerations when determining the best pressure instrument for an application. Measurement range of the instrument must first be considered. All pressure measurement devices have a limited range of use, so it is important to select a device that can measure the pressure in your application. Next, consider the measurement accuracy and stability required from the device. Measurement accuracy and stability generally increase as you move from switches to pressure gauges to pressure transducers to pressure transmitters. Finally, reliability of the device increases in importance along with the criticality of the pressure measurement.​
There are three different types of pressure measurement. Absolute pressure is the pressure measured relative to a perfect vacuum. Gauge pressure is the difference between absolute pressure and atmospheric pressure. Differential pressure is the difference in pressure between two measured pressures.
Pressure transmitters and pressure gauges can be used in a variety of industries and applications. They can use flanged, threaded or industry specific connections to adapt to the process and provide reliable readings. Additional connections with a remote seal or integral manifold can provide functionality for necessary calibration and maintenance.​
Some common instruments used to measure industrial pressure include manometers, switches, pressure gauges, pressure transducers and pressure transmitters. Selecting the right technology for your application should include important considerations such as measurement range, accuracy and stability and reliability.​
