Product Overview

The Bently Nevada 330101-00-10-10-12-05 is a high-integrity 8mm eddy current proximity probe engineered for the 3300 XL Transducer System. This sensor is a fundamental element of Turbine Supervisory Instrumentation (TSI), providing non-contacting measurement of shaft movement. It operates by generating a high-frequency magnetic field that translates the distance to a conductive target into a precise voltage output when connected to a Proximitor Sensor.

This probe is specifically designed for the continuous monitoring of fluid-film bearing machines. It enables accurate tracking of radial vibration for rotordynamic analysis and axial position for thrust safety. Additionally, its high-frequency response makes it an industry standard for Keyphasor signals and rotational speed measurements, ensuring both static and dynamic machinery protection.

Technical Characteristics and Construction

• API 670 Standard Alignment: Fully complies with American Petroleum Institute (API) 670 requirements for linear range, accuracy, and temperature stability, ensuring suitability for critical machinery protection.

• Ruggedized 8mm Design: Features a reinforced probe body and thicker encapsulation than smaller 5mm variants, providing superior mechanical strength and resistance to physical stress.

• Universal Match Technology: Engineered for total interchangeability within the 3300 XL series. Probes, extension cables, and sensors can be swapped without requiring time-consuming manual bench calibration.

• Signal Integrity: Designed to maintain a stable scale factor of 7.87 V/mm (200 mV/mil) over its standard linear range when used with the appropriate system length.

• Environmental Protection: Compatible with optional connector shields and guards to protect internal junctions from oil, moisture, and mechanical damage during conduit routing.

• High-Temperature Resilience: Built to withstand the harsh internal environments of turbines and compressors, maintaining precision across a wide thermal spectrum.
