Quick Detail

Description

The 330709-000-030-10-02-00 3300 XL 11 mm Proximity Probes represent a significant advancement in non-contact displacement sensing technology, specifically designed by Bently Nevada for high-precision machinery diagnostics. As a core component of the 3300 XL 11 mm Proximity Probes system, the 330709-000-030-10-02-00 model is engineered to provide a wider linear range compared to standard 8 mm probes, making these 3300 XL 11 mm Proximity Probes indispensable for monitoring large-scale rotating equipment. By utilizing the eddy current principle, the 3300 XL 11 mm Proximity Probes accurately detect the distance between the probe tip and a conductive target, delivering critical data on shaft vibration, axial position, and rotor eccentricity.

The mechanical construction of the 330709-000-030-10-02-00 ensures survival in the most punishing industrial environments. These 3300 XL 11 mm Proximity Probes incorporate the patented TipLoc molding process, which creates an inseparable bond between the probe tip and the body, and the CableLoc design, providing a high pull strength of 330 N to prevent accidental cable detachment. This specific 3300 XL 11 mm Proximity Probes variant features a 30 mm overall case length and 0 mm unthreaded length, optimized for flush-mount or direct-entry installations into bearing housings where space is a premium.

Signal integrity is maintained through the use of gold-plated ClickLoc connectors. The 330109-000-030-10-02-00 is equipped with a miniature coaxial connector and a factory-installed connector protector, ensuring the 3300 XL 11 mm Proximity Probes remain immune to moisture, oil wicking, and vibration-induced signal noise. With a 4 mm (160 mils) linear range, these 3300 XL 11 mm Proximity Probes offer double the measurement span of standard systems, providing greater flexibility for machines with significant thermal expansion or axial float.

Applications:

The 330709-000-030-10-02-00 is primarily deployed in large-scale rotating machinery where a standard 8 mm probe's range is insufficient. Its 4 mm linear range makes it ideal for monitoring the axial thrust position of large steam and gas turbines. In these applications, the probe tracks the rotor's longitudinal movement relative to the thrust bearing, providing an early warning of bearing wear or potential catastrophic internal contact during high-load operations or thermal transients.

In the petrochemical and mining sectors, these 3300 XL 11 mm Proximity Probes are used to monitor shaft radial vibration in heavy-duty compressors and large-diameter pumps. The 30 mm compact case length allows the probe to be installed in tight bearing housings without requiring extensive modifications. By providing high-resolution vibration data, the 330709-000-030-10-02-00 enables maintenance teams to identify rotor imbalances, misalignments, and fluid-film bearing instabilities, thereby supporting predictive maintenance schedules and reducing unplanned downtime.

This probe model also serves as an essential tool for measuring rotor eccentricity and differential expansion in power plant generators. Because the 330709-000-030-10-02-00 can operate reliably in temperatures ranging from -52°C to +160°C, it is perfectly suited for mounting near high-temperature turbine stages. The 1.0-meter integrated cable facilitates easy connection to extension cables and Proximitor* sensors, ensuring stable data transmission for Keyphasor* reference and speed measurements even in electrically noisy environments.

Specifications

Competitive Advantage

1. Extended 4 mm Linear Measurement Range

The most significant advantage of the 330709-000-030-10-02-00 is its 4 mm (160 mils) linear range, which is twice the capacity of the standard 3300 XL 8 mm probes. This allows for more forgiving installation tolerances and the ability to monitor machines with larger shaft orbits or significant axial movement. It provides engineers with a much wider "window" of observation, ensuring that critical data is not lost even during extreme machine conditions.

2. Patented Mechanical Robustness (TipLoc & CableLoc)

Bently Nevada’s proprietary TipLoc and CableLoc technologies provide a level of durability that competitors cannot match. The 330709-000-030-10-02-00 is designed to withstand a cable pull force of up to 330 N (75 lb), significantly reducing the risk of failure during installation or when cables are routed through complex machine internals. This mechanical integrity ensures a longer service life and higher return on investment for machinery protection systems.

3. Superior Signal Stability and Noise Immunity

Featuring a low supply sensitivity (less than 1 mV/V) and a controlled extension cable capacitance of 68.7 pF/m, the 330709-000-030-10-02-00 ensures an incredibly stable output signal. The gold-plated ClickLoc connectors and included connector protector shield the signal from moisture and electromagnetic interference (EMI). This results in a high signal-to-noise ratio, preventing false alarms and ensuring that the data used for machine trips is accurate and reliable.
