Bently Nevada 330101-00-63-10-02-00 3300 XL 8 mm Proximity Probe
The Bently Nevada 330101-00-63-10-02-00 is a 3300 XL 8 mm proximity probe with a 6.3m unarmored cable and 3/8-24 UNF threads. This non-contact eddy current sensor provides critical vibration and position monitoring for high-speed rotating industrial machinery.
Technical Overview
The Bently Nevada 330101-00-63-10-02-00 is a high-precision eddy current sensor designed for non-contact measurement of vibration and position. As a core component of the 3300 XL 8 mm Transducer System, this probe monitors the dynamic and static distance between the sensor tip and a rotating shaft. Because the system utilizes electromagnetic induction, it provides highly accurate data even in presence of oil, water, or steam, making it the industry standard for machinery protection in critical rotating assets.
Configuration and Design Features
This specific probe configuration is engineered to meet precise mechanical and electrical installation requirements. The 330101 series features a 3/8-24 UNF threaded body, which allows for standard mounting in bearing housings. With a “63” unarmored cable length (6.3 meters), this model provides significant reach for routing through internal machine spaces without the bulk of stainless steel armor.
The probe tip consists of high-strength polyphenylene sulfide (PPS), which provides a hermetic seal against harsh industrial fluids. Furthermore, the unit features a miniature coaxial connector (02) and follows a 1.0-meter (10) total length calibration for the probe lead itself. Consequently, when paired with a matching 3300 XL Proximitor sensor and extension cable, the system delivers a linear scale factor of 200 mV/mil (7.87 V/mm) over a 2.0 mm range.
