Quick Detail

Description

The 330104-00-12-10-02-00 3300 XL 8 mm Proximity Probe is engineered as a high-reliability sensing component designed for demanding vibration and displacement monitoring tasks in industrial rotating machinery. As part of the 3300 XL family, the 3300 XL 8 mm Proximity Probe integrates advanced eddy-current measurement technology to ensure accurate, stable, and repeatable performance across a wide range of operating conditions. This model is fully aligned with the mechanical and performance criteria defined in API 670, supporting consistent linearity, thermal stability, and long-term measurement integrity.

One of the defining strengths of the 3300 XL 8 mm Proximity Probe is its complete interchangeability within the 3300 XL ecosystem. The probe can be paired seamlessly with matching extension cables and Proximitor® sensors without requiring custom calibration or matching procedures. Backward compatibility with earlier 3300-series 5 mm and 8 mm components further enhances installation flexibility, making this probe suitable for both system upgrades and mixed-generation monitoring configurations.

This upgraded design incorporates the patented TipLoc® process, which reinforces the mechanical bond between the probe body and tip, delivering improved durability in high-vibration environments. The CableLoc® technology enhances tensile strength to approximately 330 N (75 lbf), ensuring that the cable-to-probe connection remains secure even under continuous mechanical stress. For installations exposed to lubricants or process fluids, the 3300 XL 8 mm Proximity Probe can also be equipped with an optional FluidLoc® sealing structure that prevents internal fluid migration along the cable.

The probe’s 8 mm sensing coil benefits from increased encapsulation thickness and a more robust PPS molded housing, providing superior mechanical protection and structural rigidity. This makes the 3300 XL 8 mm Proximity Probe the preferred choice in harsh industrial settings where physical abuse or thermal cycling is common.

Applications

The 330104-00-12-10-02-00 3300 XL 8 mm Proximity Probe is engineered for high-accuracy shaft vibration and position measurements in demanding industrial environments. With its 120 mm overall case length, 1.0-meter total cable length, and the reliable miniature coaxial ClickLoc connector, the probe is ideal for installations where stable mechanical coupling and signal integrity are essential. Designed to operate within a wide temperature range from –52°C to +177°C, the probe performs reliably in harsh conditions commonly found in petrochemical, power generation, and heavy-duty rotating machinery applications.

This proximity probe is widely deployed in turbomachinery monitoring, including steam turbines, gas turbines, compressors, pumps, and motors. Its 2 mm linear range enables precise detection of shaft movement, making it suitable for measuring radial vibration, axial position, thrust position, and shaft runout. The probe’s low supply sensitivity—less than 2 mV change per volt of input variation—ensures stable output signals, even under fluctuating power supply conditions.

In addition, the probe’s 50-ohm output resistance and optimized cable capacitance of 69.9 pF/m enhance signal fidelity over longer cable runs, supporting accurate data transmission to proximitor monitors. Its rugged construction and compliance with strict industrial reliability requirements make it suitable for API 670-based monitoring systems, condition-based maintenance programs, and continuous online vibration protection systems.

Thanks to its compact 110 × 2 × 1.6 cm physical profile and lightweight 0.14 kg design, the 3300 XL 8 mm probe is particularly well-suited for applications where space is limited or multiple sensing points are required. It can be easily integrated into bearing housings, turbine casings, gearboxes, and other critical rotating equipment. Whether used in refineries, chemical plants, power stations, or advanced manufacturing facilities, the probe provides consistent and accurate proximity measurements essential for equipment protection, operational safety, and long-term asset reliability.
