Introduction to Continuous Pressure Measurement
Introduction to Continuous Pressure Measurement - Overview
In many ways, pressure is the primary variable for a wide range of process measurements. Many types of industrial measurements are actually inferred from pressure, such as:
- Flow (measuring the pressure dropped across a restriction)
- Liquid level (measuring the pressure created by a vertical liquid column)
- Liquid density (measuring the pressure difference across a fixed-height liquid column)
- Weight (hydraulic load cell)
Even temperature may be inferred from pressure measurement, as in the case of a fluid-filled chamber where fluid pressure and fluid temperature are directly related. As such, pressure is a very important quantity to measure, and measure accurately. This section describes different technologies for the measurement of pressure.

hello there;
if i have continous real signal (4-20 ma) from pressure smart sensor, so to get high precision should i choose input module with high resolution? then i should use instruction ladder to make scaling of signal but. so what i do to this signal to make my pc to read this signal by modbud tcp/ip with saving of real signal in high precision.
regards
