Pressure Transducers
A pressure transducer/sensor measures pressure, typically of gases, liquids or solids. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure transducer generates an electrical signal as a function of the pressure imposed. They can also be used to indirectly measure other variables such as fluid/gas flow and speed. The pressure transducer used at MORE measures gauge pressure. The pressure transducers used are either single ended or differential pressure measurement devices. The data acquisition for the pressure transducer consists of an A/D converter, which converts the pressure fluctuations into electrical signals. The time series signals obtained from the transducer are then analyzed statistically and chaotically to obtain important information about the multiphase systems under study. These help in understanding the flow pattern and flow dynamics of multiphase systems.
