Product Overview

The Bently Nevada 330101-00-11-20-02-00 is a high-accuracy 8mm eddy current proximity sensor engineered for the 3300 XL monitoring platform. This transducer serves as a non-contacting displacement sensor, capturing essential data on shaft vibration and axial position. It operates by detecting the precise physical gap between the sensor tip and the conductive target material, providing the high-fidelity signal necessary for Proximitor sensors to generate a stabilized analog voltage.

As a core element of Turbine Supervisory Instrumentation (TSI), this 330101-00-11-20-02-00 probe is designed for long-term stability in high-speed rotating assets. It is widely deployed in power generation and petrochemical facilities to monitor machines with fluid-film bearings, enabling early fault detection through precise radial and axial displacement tracking.

Core Technical Characteristics

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

• Universal Component Match: Part of the 3300 XL "universal match" architecture, allowing this probe to be swapped with any 3300 XL extension cable and sensor of the same system length without manual bench calibration.

• ClickLoc Connectivity: Equipped with a gold-plated miniature coaxial ClickLoc connector on a 2.0-meter lead, ensuring a vibration-resistant electrical junction that requires no specialized tools for field installation.

• Advanced Signal Integrity: Delivers a voltage output directly proportional to the gap, maintaining exceptional linearity and a standard scale factor of 7.87 V/mm (200 mV/mil).

• Enhanced Compatibility: Fully interoperable with legacy non-XL 3300 series 5mm and 8mm transducer system components, offering a flexible upgrade path for existing infrastructure.

• Ruggedized Construction: Features an unarmored standard cable designed for easy routing through conduits while remaining resilient against industrial contaminants and thermal stress.
