Bently Nevada TK-3e Proximity Test Kit

This self-contained test kit verifies the performance and calibration of proximity transducer systems. It combines a target, micrometer, and power supply in a portable carrying case. The kit enables quick, on-site testing of eddy current probes and drivers.

Test Mechanism and Operating Principle

The Bently Nevada TK-3e kit includes a micrometer-driven target that simulates shaft movement for system testing. Rotating the micrometer moves the target toward or away from the proximity probe tip. This motion generates a change in the probe’s output voltage, reflecting actual gap variations. The kit’s design ensures reliable testing of Bently Nevada 3300, 7200, and 3000 series proximity systems.

Calibration and System Verification

Technicians use the micrometer to set precise gap distances for linearity and sensitivity verification. The kit detects probe and driver problems by comparing the actual output against expected values. It also checks cable continuity and connector integrity in the measurement chain. The included NIST-traceable certificate ensures confidence in the test results. The portable case provides safe storage and transport between test locations.

Application Use

Reliability engineers and instrument technicians use this kit for routine proximity probe system checks. It serves as an essential tool for commissioning new machinery installations. The kit also assists during troubleshooting of vibration monitoring systems. Its compact design allows easy field deployment without external power sources. The kit’s simplicity reduces the need for complex test setups.
