TK-3G Bently Nevada Air Powered Vibration Calibrator

Overview

The Bently Nevada TK-3G (Air Driven) is a portable proximity system calibration kit used to verify and calibrate machinery protection systems that rely on proximity transducers. Often referred to as a “Wobbulator,” it provides both static (position) and dynamic (vibration) simulation of a rotating shaft.

The air-driven design makes it ideal for environments where compressed air is available or where using electrical power may pose safety concerns. Regular use ensures that proximity probes, extension cables, and monitoring electronics operate reliably, maintaining machine protection and regulatory compliance.

Technical Data (Typical)

Typical Applications

• Pre-Startup Verification: Confirms proper installation and operation of proximity probes on new machinery.

• Routine Calibration Checks: Ensures long-term accuracy of turbine, compressor, and pump monitoring systems.

• Troubleshooting Monitor Alarms: Validates monitor and sensor operation when unexpected alarms occur.

• Hazardous or Electrical-Sensitive Areas: Air-driven operation is preferred where portable electrical power is restricted.

FAQ: Bently Nevada TK-3G

Q1: Why choose air-driven (TK-3G) over electric-driven (TK-3E)?
A1: Air-driven is preferred where compressed air is available and portable electrical power may be unsafe or restricted. Both models provide the same calibration functionality.

Q2: Can the TK-3G check the Proximitor® sensor scale factor?
A2: Yes. The static spindle micrometer allows verification of the sensor’s sensitivity by measuring DC output changes for known gap distances.

Q3: What types of systems can the TK-3G verify?
A3: It verifies the entire proximity transducer system, including the probe, extension cable, and Proximitor® sensor, ensuring the accuracy of the signal path from shaft to monitor.
