Product Overview

The Bently Nevada 330104-08-14-05-01-00 is a high-precision 8mm eddy current sensor designed for the 3300 XL proximity transducer system. This specific configuration features a metric M10 x 1 threaded body and integrated stainless steel armor, providing superior mechanical protection for the lead cable in harsh industrial environments. It serves as a non-contacting displacement sensor, capturing real-time data on shaft vibration and axial position for critical rotating assets.

By converting the distance between the probe tip and a conductive target into a linear voltage signal, this transducer enables comprehensive machinery protection. It is a fundamental component of Turbine Supervisory Instrumentation (TSI), widely utilized in power generation, oil and gas, and petrochemical facilities to monitor machines equipped with fluid-film bearings.

Core Technical Characteristics

• Metric Mechanical Interface: Engineered with an M10 x 1 mounting thread, an 80 mm unthreaded length, and a 140 mm total case length, making it ideal for deep-port installations in metric-standard machinery.

• Integrated Stainless Steel Armor: The lead cable is encased in flexible stainless steel armor, offering exceptional durability against abrasion, mechanical impact, and sharp bends in the field.

• Universal Match Technology: Fully compatible with any 3300 XL Proximitor sensor and extension cable of the same system length, allowing for component replacement without the need for manual bench calibration.

• Miniature ClickLoc Connectivity: Features a gold-plated coaxial ClickLoc connector on a 0.5-meter (1.6 feet) lead. This connector provides a vibration-proof junction and includes a protective cover to prevent contamination.

• API 670 Standard Compliance: Adheres to the American Petroleum Institute’s stringent requirements for mechanical configuration, linear range, and thermal stability in machinery protection systems.

• Robust Signal Integrity: Maintains a standard scale factor (SSF) of 7.87 V/mm (200 mV/mil) when targeting AISI 4140 steel, ensuring high-fidelity data for predictive maintenance.
