The Bently Nevada 330104-00-09-05-02-05 Proximity Probe Module is a high-accuracy non-contact eddy-current sensor developed for continuous monitoring of shaft vibration, axial position, radial displacement, and rotor movement in industrial rotating equipment. Belonging to the industry-proven 3300 XL 8 mm Proximity Transducer System, this probe is engineered to deliver exceptional measurement stability, long-term reliability, and dependable performance in demanding industrial and hazardous-area environments.
This configuration incorporates a 90 mm probe case length (Option 09), a compact 0.5-meter system length (Option 05), a secure ClickLoc connector configuration (Option 02), and a hazardous-area certification package (Option 05). The combination of compact installation dimensions and safety approvals makes it an excellent choice for turbine enclosures, compressor skids, offshore platforms, refinery equipment, and other applications where installation space is limited but reliability is critical.
Designed to support predictive maintenance programs, the 330104-00-09-05-02-05 helps operators identify machinery issues such as imbalance, misalignment, shaft rub, and bearing degradation before they result in costly downtime or equipment failures.
