Pressure measurement terminology and references
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.
