Product Overview

The Bently Nevada TK-3E 177313-02-02-00 is a specialized calibration instrument designed for the field verification of proximity transducer systems and vibration monitors. This electric-driven kit simulates both static and dynamic shaft conditions to ensure that monitoring hardware accurately reflects the behavior of rotating machinery. By utilizing a precision spindle micrometer and a motor-driven wobble plate, the TK-3E allows technicians to confirm that proximity probes are properly gapped and that the resulting voltage outputs align with established scale factors. It is a fundamental tool for maintaining the integrity of Turbine Supervisory Instrumentation (TSI), ensuring that machinery protection systems remain compliant with industry standards such as API 670.

Industrial Maintenance Applications

• Dynamic Monitor Verification: Uses the motorized wobble plate to simulate mechanical vibration, allowing for the direct testing of high-vibration alarm and shutdown thresholds on Bently Nevada 3500 series racks.

• Proximitor Sensor Calibration: Enables precise mapping of the Average Scale Factor (ASF) for 3300 XL and other proximity probe series by measuring DC voltage changes against known micrometer movements.

• TSI Troubleshooting: Serves as a portable diagnostic station for identifying faulty probes, extension cables, or Proximitor sensors in steam turbines, compressors, and high-speed pumps.

• Annual Safety Audits: Facilitates documented proof of calibration for industrial facility safety audits, ensuring all sensors meet the required ±5% accuracy tolerance.

• Shaft Position Simulation: Bench-tests thrust position monitors by simulating axial shaft movement to verify the correct orientation and response of axial displacement probes.

FAQ

Q: What is the difference between the TK-3E and the manual TK-3 versions?

A: The TK-3E 177313-02-02-00 includes an electric motor to drive the wobble plate, providing a consistent and repeatable vibration signal. Manual versions require the user to manually turn a spindle, which is less ideal for testing dynamic monitor responses.

Q: Does this kit include the micrometer for static testing?

A: Yes, the kit features a removable spindle micrometer assembly. This allows for highly accurate static calibration of the probe gap and verification of the linear range of the Proximitor sensor.

Q: Can the TK-3E be used on probes larger than 19mm?

A: The standard universal probe mount provided in this kit is designed for probes ranging from 5mm to 19mm. For larger or non-standard probes, specialized adapter bushings may be required.

Q: How often should the TK-3E itself be calibrated?

A: To maintain the accuracy of your machinery protection system, it is recommended that the TK-3E micrometer and spindle assembly be recertified annually against NIST-traceable standards.

Q: Is this kit suitable for hazardous area use?

A: The TK-3E is an electric-driven tool intended for use in safe areas or under a hot-work permit. Always ensure the local environment is verified as non-hazardous before operating the electric motor.
