How to conduct vibration test on TK3-2E

The TK3-2E calibrator simulates shaft vibration and displacement to calibrate monitors. It verifies the operating status of the monitor reading device and the status of the eddy current sensor system. A properly calibrated system means accurate readings and sensor inputs. A spindle micrometer is used to check the sensor system and calibrate the displacement monitor. The probe mounting connector supplied with the TK3-2E holds the probe in place while the target surface moves toward or away from the probe tip in calibrated increments. The output of the presensor is recorded with a voltmeter. The vibration monitor is calibrated using a motor-driven tilting disk. There is a rocker holder on the disc to fix the eddy current probe. By adjusting the holder and probe to the appropriate position, the mechanical vibration magnitude can be brought to the desired value. This mechanical vibration is measured by a dial micrometer in the calibration device (no oscilloscope is required). Vibration monitor readings can be compared to a known mechanical vibration signal output (i.e., a dial indicator reading).
