The Bently Nevada TK-3E 177313-02-02-00 is an essential precision instrument designed for the onsite calibration and verification of Bently Nevada proximity transducer systems. As a critical component of any Machinery Condition Monitoring (MCM) program, the TK-3E simulates shaft vibration and position, allowing technicians to verify the linearity and voltage output of Proximitor sensors, probe leads, and extensions. By ensuring the accuracy of your vibration monitoring hardware, this kit prevents false trips and ensures that genuine machinery faults are detected before they lead to catastrophic failure.
The TK-3E is engineered for rugged field use while maintaining laboratory-grade accuracy.

Understanding the specific configuration of your 177313 series kit is vital for regional and application compatibility. The suffix breakdown for this specific unit is as follows:
177313: Base Model Number for the TK-3E Electric Driven Proximity System Test Kit.
-02 (Scale Units): Metric Units. The micrometer and spindle assembly are calibrated in millimeters (0 - 25.4 mm) rather than English/Imperial units.
-02 (Power Cord): European/Universal Power Cord. This specifies the plug type and voltage compatibility suitable for European and international standard outlets (Schuko style).
-00 (Agency Approval): None. This indicates the standard version for use in non-hazardous (safe) areas, without specific ATEX/IECEx intrinsic safety certifications for the kit itself.
The TK-3E is a standalone diagnostic tool, but proper setup is required to obtain valid calibration data.
Mounting the Probe: Insert the proximity probe into the probe adaptor (collet) provided in the kit. Ensure the probe tip is flush and centered against the AISI 4140 steel target button.
Static Calibration (Position): Connect the Proximitor sensor output to a calibrated Digital Multimeter (DMM). Use the micrometer to move the probe away from the target in increments (e.g., 0.25 mm). Record the DC voltage change to verify the scale factor (typically 7.87 V/mm or 200 mV/mil).
Dynamic Calibration (Vibration): Use the electric motor to spin the "wobble plate." Adjust the probe position until the desired peak-to-peak vibration is observed on your monitoring rack or portable data collector.
Wiring Configuration:
Power: Plug the kit into a grounded AC outlet (90-264 VAC).
Signal: Use BNC-to-Banana adapters to interface the Proximitor "OUT" and "COM" terminals with your measurement equipment.
Q: Can I test probes from other manufacturers with the TK-3E?
A: While the mechanical movement can be measured, the target button is specifically calibrated for AISI 4140 steel, which is the standard for Bently Nevada 3300/3300 XL series. Other materials will result in incorrect voltage readings due to different magnetic permeability.
Q: How often should the TK-3E itself be calibrated?
A: To maintain ISO compliance and MCM integrity, we recommend factory calibration of the TK-3E micrometer and wobble plate assembly every 12 months.
Q: Does the -02 power cord work in the USA?
A: The -02 suffix denotes a European cord. While the internal motor is universal (90-264V), you would need a plug adapter or a standard C13 "IEC" power cable to use it with US NEMA 5-15 outlets.
