TK3 Proximity System Test Kit Introduction

The TK-3 Proximity System Test Kit simulates shaft vibration and position for calibrating Bently Nevada monitors.  It verifies the operating condition of the monitor readouts as well as the condition of the proximity transducer system.  A properly calibrated system ensures that the transducer inputs and the

resulting monitor readings are accurate.

 The TK-3 uses a removable spindle micrometer assembly to check the transducer system and position monitor calibration.  This assembly features a universal probe mount that will accommodate probe diameters from 5 mm to 19 mm (0.197 in to 0.75 in).  The mount holds the probe while the user moves the target toward or away from the probe tip in calibrated increments and records the output from the Proximitor Sensor using a voltmeter.  The spindle micrometer assembly also features a convenient magnetic base for ease of use in the field.

Vibration monitors are calibrated using the motor-driven wobble plate.  A swing-arm assembly located over the wobble plate holds the proximity probe in place.  This assembly uses a universal probe mount, identical to that used with the spindle micrometer assembly.  By using the absolute scale factor of the proximity probe in conjunction with a multimeter, the user adjusts the probe to find a position where the desired amount of mechanical vibration (as determined by peak-to-peak DC voltage output) is present.  No oscilloscope is needed.
