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.
A variable reluctance sensor (VRS), also called a monopole, is used to measure position and speed of moving metal components. This sensor consists of a permanent magnet, a ferromagnetic pole piece, a magnetic pickup, and a rotating toothed wheel. As the teeth of the rotating wheel (or other target features) pass by the face of the magnet, the amount of magnetic flux passing through the magnet and consequently the coil varies. When the gear tooth is close to the sensor, the flux is at a maximum.
