Purpose of pressure measure

Of all the process variables that are likely to be encountered by an Instrumentation trades person, pressure is unique in its variety of application. In industry, pressure is a common variable of and by itself, but is also used in the measurement of level, density, temperature and flow. It is for this reason that we begin the series of measurement courses with Pressure. It is also the most common variable that is measured differentially, that is, as a relative difference between two points. Finally pressure — in the form of pneumatics — is widely applied in a large range of measuring, indicating and controlling devices.

While most modern pressure measuring devices employ digital electronic circuits, the underlying principles of pressure sensing and measurement remain unchanged.

Pressure References

Pressure has two distinct reference points in common usage, Atmospheric Pressure and Gauge Pressure Atmospheric pressure is the force per unit area exerted against a surface by the weight of air above that surface in the Earth’s atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. Low pressure areas have less atmospheric mass above their location, whereas high pressure areas have more atmospheric mass above their location. Similarly, as elevation increases there is less overlying atmospheric mass, so that pressure decreases with increasing elevation. A column of air one square inch in cross-section, measured from sea level to the top of the atmosphere, would weigh approximately 65N. Most pressure measuring instruments take their zero point from atmospheric pressure. The value indicated being called gauge pressure. Instruments that measure gauge pressure sometimes use the lette
