TK3 Proximity System Test Kit
Datasheet
Bently Nevada Machinery Condition Monitoring
Description
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.
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-topeak.
