Sound, consisting of waves of varying air pressure, is converted to its electrical form by a transducer, such as a microphone. |
For these exams, the transducer is attached to a probe that's inserted into a natural opening in your body. |
At least one fluid device from a group consisting of a flow controller, a valve, a filter and a pressure transducer is provided. |
The angular transducer data are used for the assessment of the track gauge and to determine the trolley wobble between the rails. |
The transducer was cabled to a control and data-acquisition unit consisting of a computer and other electronic hardware. |
The electric power applied to the transducer was measured using a sampling wattmeter. |
