What are pressure transducers used for?

Answer 1

== The most common use of piezoelectric transducers is in sonography. That's sonar. And medical sonography, the so-called ultrasound, represents the broadest application of the technology. The ultrasound is in use in medical imaging right now in a number of places around the world. It is very common for pregnant women to undergo the proceedure. They are also used in speakers and the like, in applications as a "force gauge" and as a method of control for scanning tunneling microscopy. They are also used in basic physics research such as the study of so-called Fermi surfaces where ultrasound is passed through a crystalline sample in a magnetic field. == Piezoelectric transducers are used to measure dynamic events. The events a piezoelectric tranducer can measure is typically relative to a force. Such as vibration (dynamic g forces), force / impact (dynamic in nature), and pressure (once again dynamic). Piezoelectric transducers do not measure true static events. Such as your weight when stepping on a scale. What a piezoelectric will measure is the impact of your body stepping on the scale and any changes in force applied to the scale. Some examples of use would be in manufacturing where a press is being used rapidly. Piezoelectric pressure sensors are used to measure the dynamic events of pressure. Such as the turbulance in a pipe or combustion pressures in an engine. Piezoelectric accelerometers measure g forces dynamically. This is generically considered vibration. This measurement can detect bearing faults in a motor from its 'vibration' or the structural integrity of an aircraft based on its vibration and response to the forces put into the structure. A material that generates an electric charge when mechanically deformed. Conversely, when an external electric field is applied to piezoelectric materials they mechanically deform. This above effect is called Piezoelectric effect Every day use of this phenomena is used in load cells. Load cells are used on large weigh scales for trucks and large bin scales where materials need to be weighed. The signals from the cells are calibrated to compensate for the weight of the scale so that the scale can be zeroed out. The cell signal because it is very small is sent to an amplifier head where is can be read by the operator in units of weight. The head unit can be set to read in metric or imperial weights.

Answer 2

A pressure transducer is sometimes referred to as a pressure sensor, pressure transmitter or piezometers, to name a few. They are used to measure pressure, or force, of gasses or liquids.
