The CMCP-TKPW Pocket Wobulator is used to provide a calibrated mechanical vibration using a variable speed Wobble Plate. A precision dial indicator is placed in the probe shuttle and set at the desired amplitude. The dial indicator is then replaced with a proximity probe to simulate vibration signals. Both the proximity probe system and monitoring system can be verified by this method. The CMCP-TKPW's Wobble Plate is made from 4140 Steel, the standard material used for proximity probe calibration, and features a 0-15 mil (0-381 Micron) dynamic range. calibrations.
