Displacement sensors produce outputs that can be observed in real-time on an oscilloscope or with a data-acquisition system. This real-time, instantaneous data provides precise vibration data which can be used to determine a machineâs performance as a function of time or angular location of a rotating part.
Ultrasonic sensors are based on measuring the properties of sound waves with frequency above the human audible range. They are based on three physical principles: time of flight, the Doppler effect, and the attenuation of sound waves. Ultrasonic sensors are non-intrusive in that they do not require physical contact with their target, and can detect certain clear or shiny targets otherwise obscured to some vision-based sensors. On the other hand, their measurements are very sensitive to temperature and to the angle of the target.
