Description

The 330105-02-12-15-12-05 3300 XL 8 mm Reverse Mount Probes represent the pinnacle of eddy current proximity sensing technology, specifically developed by Bently Nevada for high-precision industrial machinery monitoring. This 3300 XL 8 mm Reverse Mount Probes system is engineered to deliver exceptional accuracy and long-term stability in non-contact displacement measurements. As a critical component of the 3300 XL series, the 330105-02-12-15-12-05 model utilizes a specialized reverse-mount configuration. This unique design allows the 3300 XL 8 mm Reverse Mount Probes to be installed from the internal or opposite side of a mounting surface, making it an indispensable solution for machine housings where external access is restricted or axial clearance is extremely tight.

Operating on the advanced eddy current principle, the 3300 XL 8 mm Reverse Mount Probes generate a high-frequency electromagnetic field that detects the distance between the probe tip and a conductive target. The 330105-02-12-15-12-05 ensures a highly linear voltage-to-gap relationship, enabling maintenance teams to monitor both static parameters, such as thrust bearing wear and rotor position, and dynamic signals like radial vibration. With a robust 2 mm (80 mils) linear range, these 3300 XL 8 mm Reverse Mount Probes provide the high-resolution data necessary for API 670 compliant machinery protection systems.

Applications

The 330105-02-12-15-12-05 is primarily utilized in heavy-duty rotating machinery within the power generation and oil and gas sectors. Its reverse-mount design is specifically suited for monitoring shaft vibration and axial position in steam turbines, gas turbines, and large centrifugal compressors. Because it can be installed in tight internal cavities where standard forward-mount probes cannot reach, it is the preferred choice for fluid-film bearing housings and gearbox assemblies requiring precise gap measurement without compromising machine casing integrity.

In the petrochemical and processing industries, these 3300 XL 8 mm Reverse Mount Probes are essential for predictive maintenance of high-speed pumps and motors. With an operating temperature range reaching up to +177°C and a FluidLoc cable that prevents fluid migration through the wire, the probe excels in environments saturated with synthetic lubricants or hazardous chemicals. It provides critical data for detecting rotor imbalances, misalignments, and bearing degradations, helping facilities avoid catastrophic equipment failure and unscheduled downtime.

Beyond vibration monitoring, the 330105-02-12-15-12-05 serves as a high-reliability Keyphasor* sensor for speed sensing and phase reference measurements. Its ability to provide accurate timing pulses from a rotating shaft allows for sophisticated diagnostic analysis, such as orbit plots and Bode diagrams. Compliant with international standards like ATEX and IECEx, this probe is safely deployed in hazardous zones, supporting complex monitoring tasks in maritime propulsion systems, aerospace test cells, and large-scale industrial manufacturing plants.

Specifications

Competitive Advantage

1. Optimized Design for Restricted Space Installations

The 330105-02-12-15-12-05 features a specialized reverse-mount architecture with a 60 mm case length and 0 mm unthreaded length. This configuration is a significant advantage in modern, compact machinery where external mounting space is non-existent. By allowing installation from the "inside-out," it eliminates the need for bulky external brackets, providing a streamlined profile that fits into narrow bearing housings and precision instruments where traditional probes are physically too large to deploy.

2. Superior Material Durability and Environmental Protection

Equipped with a Polyphenylene Sulfide (PPS) tip and AISI 304 stainless steel housing, this probe offers industry-leading resilience against corrosive agents and mechanical stress. The inclusion of the FluidLoc cable technology is a major competitive edge, as it creates a seal that prevents oil and other process fluids from leaking through the cable's interior. This ensures the 330105-02-12-15-12-05 remains operational in pressurized oil environments, significantly outlasting generic sensors in harsh industrial conditions.

3. High Signal Integrity and Seamless System Integration

The 3300 XL 8 mm Reverse Mount Probes provide a highly stable 2 mm linear range with minimal supply sensitivity (less than 3 mV change per volt). This precision, combined with the gold-plated Miniature ClickLoc coaxial connectors, ensures a secure, low-impedance connection that is resistant to vibration-induced signal noise. Its full compatibility with Bently Nevada 3300 XL Proximitor* sensors and existing 3300 series racks makes it a versatile and "plug-and-play" upgrade for any facility looking to enhance its machinery protection without replacing entire monitoring systems.
