Product Overview
177314-02-00 is a Bently Nevada TK-3g air driven proximity system test kit designed for calibration and verification of eddy current proximity probe systems used in turbines, compressors, and rotating machinery. Maintenance engineers use this portable test device in power plants, refineries, and industrial facilities to simulate shaft vibration and displacement signals. The TK-3g enables accurate functional testing of probes, extension cables, and proximitor sensors without removing them from service. This capability reduces troubleshooting time and prevents unnecessary equipment shutdowns. Its air driven mechanism provides controlled vibration input, ensuring repeatable test conditions and reliable diagnostics in field environments.

Technical FAQs
What is the main function of the TK-3g test kit?
It simulates shaft vibration and displacement to verify proximity probe system performance.
Does this unit require electrical power?
No. It operates using compressed air supply.
Can it test complete proximity systems?
Yes. It validates probes, extension cables, and proximitor sensors as a complete loop.
What causes inaccurate test readings?
Unstable air pressure or improper setup of the micrometer and probe gap can affect results.
Engineering & Installation Guide
Maintain stable air pressure below 90 psi to ensure consistent vibration output during testing.
Align the probe tip precisely with the target surface to avoid measurement errors.
Perform calibration checks in a controlled environment to eliminate external vibration interference.
