Bently Nevada Machinery Condition Monitoring

178087 Rev. FDescription
The TK-3 Proximity System Test Kit simulates shaft vibrationand 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 theresulting monitor readings are accurate.
The TK-3 uses a removable spindle micrometer assembly tocheck the transducer system and position monitor
calibration. This assembly features a universal probe mountthat will accommodate probe diameters from 5 mm to 19mm (0.197 in to 0.75 in). The mount holds the probe while theuser moves the target toward or away from the probe tip in
calibrated increments and records the output from theProximitor Sensor using a voltmeter. The spindle micrometer
assembly also features a convenient magnetic base for easeof use in the field.
Vibration monitors are calibrated using the motor-driven
wobble plate. A swing-arm assembly located over thewobble plate holds the proximity probe in place. This
assembly uses a universal probe mount, identical to thatused with the spindle micrometer assembly. By using theabsolute scale factor of the proximity probe in conjunction
with a multimeter, the user adjusts the probe to find aposition where the desired amount of mechanical vibration(as determined by peak-to-peak DC voltage output) ispresent. No oscilloscope is needed.
The user can then compare a vibration monitor’s reading to
the known mechanical vibration signal input viewed by theproximity probe. The mechanical vibration signal from theTK-3 can range from 50 to 254 μm (2 to 10 mils) peak-topeak.
