Pressure measurement in instrumentation
Pressures Measurement in instrumentation In the following pages, we will discuss all the basics of pressure measurement, such as, What is pressure, what is the definition of pressure, units of pressure measurement, types of pressure sensors, working principle of different pressure primary elements, and applications of different sensors, pressure transmitter, and their calibration procedure. What is Pressure? The force per unit area is called pressure. Three main methods are used to measure pressure, absolute pressure, gauge pressure, and differential pressure. Pressure varies depending on the altitude of the site where we are measuring pressure. Weather, pressure fronts, and other conditions also affect the measurement of pressure in a process. The measurement of pressure is relative to all these factors of weather and climate, and pressure measurements are carried out in two main scales 1. gauge pressure 2. absolute pressure. Gauge press...
