Bently Nevada 330104-00-25-10-02-00 3300 XL 8mm Proximity Probe

The Bently Nevada 330104-00-25-10-02-00 is a 3300 XL 8mm metric proximity probe (M10x1) with a 1.0-meter cable and 25mm case length. It provides precision, non-contact vibration monitoring for critical industrial assets, featuring a rugged PPS tip and ClickLoc connectors.

Technical Function and System Role

The Bently Nevada 330104-00-25-10-02-00 is a high-performance eddy current sensor belonging to the 3300 XL 8mm Proximity Transducer System. This probe is designed to measure the microscopic distance (gap) between the probe tip and a rotating target, such as a shaft. By converting this physical distance into a proportional voltage signal via a Proximitor Sensor, it allows for the precise monitoring of radial vibration and axial position. Consequently, it is a foundational component for machinery protection in high-speed turbines and compressors, enabling early fault detection and preventing catastrophic mechanical failure.

Core Features and Industrial Benefits

The 330104-00-25-10-02-00 features a probe tip made of polyphenylene sulfide (PPS), which is highly resistant to chemical attack and moisture absorption. The “ClickLoc” connector (02 option) provides a gold-plated, finger-tight connection that prevents the signal from being interrupted by machine vibration. Furthermore, the 3300 XL series is fully compliant with the American Petroleum Institute (API) 670 standard for accuracy and interchangeability. This makes it a preferred choice for:

Radial shaft vibration monitoring in steam and gas turbines
Axial thrust position tracking in high-pressure compressors
Eccentricity and shaft alignment measurements
Speed and Keyphasor reference applications

Installation and System Integration

For a complete measurement loop, technicians must pair this 1.0-meter probe with a 4.0-meter extension cable (to reach a 5.0-meter system) or an 8.0-meter extension cable (for a 9.0-meter system). The probe should be installed using the M10 x 1 metric threads and gapped appropriately—typically at 1.27 mm (50 mils)—to ensure the target remains within the probe’s linear range. Moreover, the included connector protector (02 option) is essential for preventing oil and other environmental contaminants from entering the coaxial connection, which effectively eliminates potential ground loops and signal interference.
