Product Overview

The Bently Nevada 330102-00-43-05-02-05 is a high-integrity 8mm proximity transducer probe engineered for the 3300 XL series. This eddy current sensor provides non-contacting measurement of shaft displacement, converting the physical distance between the probe tip and a target conductive surface into a linear voltage signal. It is a fundamental component of Turbine Supervisory Instrumentation (TSI) systems, essential for safeguarding high-value rotating assets.

Designed for continuous industrial service, this probe excels in monitoring radial vibration and axial position on fluid-film bearing machines. Its high-resolution output also makes it an industry standard for providing Keyphasor reference signals and rotational speed measurements. By delivering precise data on both static position and dynamic shaft motion, it enables operators to detect mechanical anomalies before they lead to catastrophic equipment failure.

Core Technical Characteristics

• API 670 Standard Alignment: Specifically engineered to meet the American Petroleum Institute’s (API) 670 requirements for mechanical configuration, linear range, accuracy, and thermal stability in machinery protection.

• Enhanced Structural Integrity: Utilizes the patented TipLoc molding process to create an inseparable bond between the probe tip and body, ensuring durability under extreme pressure and vibration.

• Cable Retention System: Features the CableLoc design, providing a high pull strength of 330 N (75 lbf) to prevent accidental cable detachment during installation or operation.

• Universal Interchangeability: Fully interoperable within the 3300 XL ecosystem; probes, extension cables, and Proximitor sensors can be swapped without the need for manual bench calibration.

• Backward Compatibility: Designed for versatility, this probe is compatible with legacy non-XL 3300 series 5mm and 8mm transducer systems, facilitating cost-effective facility upgrades.

• Linear Accuracy: Maintains a standard scale factor of 7.87 V/mm (200 mV/mil) when integrated into a correctly configured 5-meter or 9-meter system.
