Bently Nevada 177314-02 Air Driven TK-3g Proximity System Test Kit

Description

The TK-3 Proximity System Test Kit is designed to simulate shaft vibration and position for the calibration of Bently Nevada monitors. It ensures the accuracy of monitor readouts and the proper functioning of the proximity transducer system. A calibrated system guarantees that the transducer inputs and the monitor readings are reliable.

The TK-3 uses a removable spindle micrometer assembly to check the calibration of the transducer system and position monitor. This assembly includes a universal probe mount that accommodates 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. Output from the Proximitor* Sensor is recorded using a voltmeter. The spindle micrometer assembly also features a magnetic base for convenience in the field.

Vibration monitors are calibrated using the motor-driven wobble plate. The swing-arm assembly above the wobble plate holds the proximity probe in place. The assembly uses the same universal probe mount as the spindle micrometer assembly. By using the absolute scale factor of the probe with a multimeter, the user adjusts the probe to find the position where the desired mechanical vibration is achieved, based on peak-to-peak DC voltage output. No oscilloscope is required.

The vibration signal from the TK-3 ranges from 50 to 254 μm (2 to 10 mils) peak-to-peak, and this allows comparison with the vibration monitor’s reading.

Caution: Rotating machinery is present. Injury can result from flying debris or contact with moving parts. Always wear safety glasses and stay clear of the wobble plate during operation.
