Quick Detail

Description

The 330705-02-18-10-02-05 is a high-precision 3300 XL 11 mm Reverse Mount Probe designed for advanced machinery protection and condition monitoring. As a critical evolution in the 3300 XL series, this 11 mm proximity probe provides a significantly extended 4.0 mm (160 mil) linear range, which is double that of standard 8 mm systems. This makes the 330705-02-18-10-02-05 particularly effective for applications where a larger gap or greater displacement measurement is required. The reverse mount configuration, featuring a 3/8-24 threaded body, is specifically engineered for internal mounting through bulkheads or within bearing housings where space for external adjustment is unavailable.

Built for maximum durability, the 3300 XL 11 mm Reverse Mount Probe utilizes Bently Nevada’s patented TipLoc molding process, ensuring an unbreakable bond between the probe tip and the stainless steel body. This is complemented by the CableLoc design, providing 330 N of pull strength to prevent cable separation in high-vibration environments. The 330705-02-18-10-02-05 comes with a 1.0-meter (3.3 feet) integrated cable terminated with a gold-plated ClickLoc miniature coaxial connector. This model also includes a connector protector, which is essential for maintaining signal integrity in humid or oil-misted environments by providing an extra layer of environmental sealing.

Applications

The 330705-02-18-10-02-05 is primarily utilized in large-scale steam and gas turbines for monitoring axial thrust position. Because the 3300 XL 11 mm Reverse Mount Probe offers a broad 4.0 mm linear range, it is ideal for machines with significant thermal expansion or axial float that would exceed the limits of a standard 8 mm probe. The reverse mount design allows the probe to be installed from the inside of the bearing casing, ensuring the probe tip is perfectly positioned even when external access to the shaft is blocked by secondary machinery components.

In the oil and gas sector, this probe is frequently applied to high-capacity centrifugal compressors. The Multiple Approvals (-05) certification allows the 330705-02-18-10-02-05 to be installed directly in Zone 0 and Zone 1 hazardous environments. It is used to capture high-fidelity radial vibration data and eccentricity readings. The integrated connector protector ensures that the signal remains clean and free from the "grounding" effects of oil and moisture that often accumulate in compressor housings, providing stable data to the Proximitor sensor via the 1.0-meter standard cable.

Specifications

Competitive Advantage

Extended 4.0 mm Linear Range for Superior Versatility The 330705-02-18-10-02-05 provides a 4.0 mm (160 mil) linear measurement range, doubling the capability of standard 8 mm probes. This allows for much larger gap settings and the monitoring of machines with wider operational tolerances, significantly reducing the risk of "probe wipes" (physical contact between the shaft and the probe tip) while maintaining high-precision signal output.

Reverse Mount Housing for Specialized Installations The specialized reverse-mount configuration of the 3300 XL 11 mm series allows for installation in locations where standard forward-mount probes cannot be adjusted. This design enables the probe to be threaded into a mounting bracket from the rear, which is indispensable for internal bearing housings or deep-well applications where space for external nuts and wrenches is restricted.

Global Hazardous Area Certification and Robust Sealing With the -05 Multiple Approvals option, this probe meets CSA, ATEX, and IECEx standards, simplifying global procurement and ensuring safety in explosive atmospheres. Furthermore, the inclusion of the ClickLoc connector with connector protector offers a superior environmental seal (IP-rated performance) compared to standard connectors, preventing oil and moisture from degrading signal quality over years of continuous operation.
