Bently Nevada TK-3E 177313-02-01 Transducer System Calibration Kit

The Bently Nevada TK-3E 177313-02-01, also cataloged as the 177313 Electric Driven TK-3e, operates as a dedicated hardware component for field verification and mechanical simulation of proximity transducer systems within 3500, 3300, and System 1 Machinery Monitoring platforms. It provides precise mechanical motion and calibrated target displacement to enable direct physical/electrical execution during transducer loop testing.

Hardware Specifications

Eddy-Current Probe Scaling & Gap Voltage Validation

The TK-3E calibration unit establishes physical positioning for verified eddy-current probe scaling acrossproximity transducer loops. By mounting the probe inside the micrometer fixture, engineers perform incremental displacement sweeps to confirm the required 7.87 V/mm (200 mV/mil) sensitivity curve. The integrated electric motor drives a calibrated wobble plate to simulate dynamic shaft vibration, facilitating gap voltage validation (-10 VDC targets) and validating Proximitor linear output response before commissioned deployment on critical machinery.

Frequently Asked Questions

Q: How does the electric motor drive in the TK-3E assist in transducer loop verification?

A: The electric motor rotates a mechanical wobble plate to generate a controlled, periodic peak-to-peak mechanical displacement signal, allowing field personnel to verify dynamic AC vibration readings on connected TSI monitors without running the machine.

Q: What is the primary operational distinction of the 02 scale unit option?

A: The 02 option designates a metric spindle micrometer, calibrating physical displacement steps in metric increments for precise gap vs. output voltage curve logging.

Field Installation Guidelines

• Mount the target button securely inside the micrometer spindle assembly, avoiding surface scratches or metallic debris accumulation on the target face.
• Position the proximity probe probe tip perpendicular to the calibration target, ensuring zero mechanical contact when advancing the micrometer spindle.
• Verify single-point earthing for external measuring instruments during signal capture to eliminate ground loop distortion on dynamic outputs.
• Close and latch the protective carrying case outer cover when operating or storing in harsh plant environments to maintain IP54 ingress protection.
