Overview
The Bently Nevada TK-3E is a portable calibration and test kit designed for verifying the performance of Bently Nevada proximity transducer systems and related condition monitoring instruments. It simulates both shaft radial vibration and axial position, allowing field engineers to ensure the accuracy of vibration and position measurements critical for machinery protection.
This test kit is widely used in steam turbines, compressors, pumps, and other rotating machinery, and it is essential for compliance with API Standard 670 and similar machinery protection standards.

Typical Applications and Usage
-
Field verification of Proximitor Sensors – ensures linearity and scale factor before installation.
-
Dynamic vibration calibration – the motor-driven wobble plate simulates shaft motion without requiring an oscilloscope.
-
Position monitor checks – the spindle micrometer provides precise, measurable gap changes for thrust or axial position sensors.
-
Maintenance and compliance – critical for machinery protection systems, ensuring accurate trip points and avoiding catastrophic failures.
The TK-3E enables high-precision, repeatable calibration in diverse field environments, making it indispensable for maintenance teams and instrumentation engineers.
Frequently Asked Questions (FAQ)
Q1: How is position monitor calibration performed using the TK-3E?
A: Using the spindle micrometer, the target is moved toward or away from the probe tip in calibrated increments. The corresponding DC voltage output from the Proximitor Sensor is recorded to verify accuracy.
Q2: Does the TK-3E require an oscilloscope for vibration calibration?
A: No. The wobulator assembly allows dynamic calibration, and the peak-to-peak DC voltage from the sensor is measured with a multimeter to calculate vibration amplitude.
Q3: Why is it important to check the proximity transducer system with the TK-3E?
A: Proximity systems can drift or be damaged, leading to incorrect shaft position and vibration readings. The TK-3E verifies that the probe, cable, and Proximitor Sensor function correctly as a unit.
Q4: Can the TK-3E be used with non-Bently Nevada proximity systems?
A: It may be used for basic verification of other systems thanks to its universal probe mount, but users should confirm scale factors and voltage requirements for non-Bently hardware.
