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 swingarm 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.
The user can then compare a vibration monitor’s reading to the known
mechanical vibration signal input viewed by the proximity probe. The
mechanical vibration signal from the TK-3 can range from 50 to 254 μm (2 to 10
mils) peak-to-peak.
