Quick Detail

Description

The 330105-02-12-10-02-05 3300 XL 8 mm Reverse Mount Probe is a high-performance eddy current proximity sensor specifically engineered for advanced industrial automation and condition monitoring systems. As part of the trusted 3300 XL 8 mm Reverse Mount Probe family, this model is designed to deliver precise, repeatable measurements of shaft position, vibration, and relative displacement in critical rotating machinery. Its reverse mount configuration provides installation flexibility in confined or non-standard mounting spaces, making the 3300 XL 8 mm Reverse Mount Probe particularly suitable for modern automated equipment layouts.

In automated machinery protection and monitoring architectures, the 330105-02-12-10-02-05 3300 XL 8 mm Reverse Mount Probe converts mechanical movement into a stable output voltage that is directly proportional to the distance between the probe tip and the monitored conductive surface. This capability allows the 3300 XL 8 mm Reverse Mount Probe to accurately capture both static values, such as shaft position and thrust, and dynamic values, including vibration and transient motion. These signals are essential inputs for PLCs, DCS platforms, and online machinery health monitoring systems used in industrial automation environments.

The 3300 XL 8 mm Reverse Mount Probe is widely applied in fluid-film bearing machines such as turbines, compressors, pumps, and generators, where continuous automation-driven diagnostics are required. In addition to vibration monitoring, the 330105-02-12-10-02-05 model supports Keyphasor® reference and speed measurement functions, enabling precise phase reference and rotational speed feedback for automated control loops and predictive maintenance algorithms.

From a design perspective, the 3300 XL 8 mm Reverse Mount Probe incorporates advanced mechanical and electrical enhancements. A patented TipLoc™ molding process strengthens the bond between the probe tip and probe body, ensuring long-term stability in harsh industrial automation environments. Meanwhile, the CableLoc™ design provides high pull-strength retention, reducing the risk of signal loss caused by vibration or cable stress. For applications involving lubricated machinery, an optional FluidLoc™ cable feature prevents oil or process fluids from migrating through the cable, improving system reliability.

Fully compliant with API 670 requirements, the 330105-02-12-10-02-05 3300 XL 8 mm Reverse Mount Probe supports complete interchangeability with compatible probes, extension cables, and Proximitor® sensors. This interchangeability simplifies automated system upgrades, reduces spare parts inventory, and minimizes downtime. As a result, the 3300 XL 8 mm Reverse Mount Probe remains a critical sensing component for high-reliability industrial automation and rotating equipment protection solutions.

Applications

Vibration Monitoring in Rotating Machinery

The 330105-02-12-10-02-05 3300 XL 8 mm Reverse Mount Probe is widely applied in continuous vibration monitoring of critical rotating machinery such as steam turbines, gas turbines, centrifugal compressors, pumps, and large electric motors. With a 2 mm linear measurement range and a recommended radial vibration gap setting of -9 Vdc, the probe delivers highly stable and accurate displacement signals. These signals are used by automated machinery protection systems and condition monitoring platforms to detect imbalance, misalignment, looseness, and bearing instability at an early stage.

Shaft Position and Thrust Measurement

In fluid-film bearing machines, the 3300 XL 8 mm Reverse Mount Probe is commonly used for shaft position and axial thrust measurement. Its non-contact eddy current sensing principle allows precise monitoring of static shaft position without mechanical wear. The robust stainless-steel probe case and PPS probe tip ensure reliable long-term operation in demanding industrial environments, even at operating temperatures ranging from -52°C to +177°C, making it suitable for both cold-start and high-temperature automation processes.

Speed and Phase Reference (Keyphasor Applications)

When configured for Keyphasor® applications, the 330105-02-12-10-02-05 probe provides accurate speed and phase reference signals for automated control and protection systems. These measurements are essential for overspeed protection, phase analysis, and advanced vibration diagnostics. The stable output resistance of 50 Ω and low supply sensitivity help ensure consistent signal quality when integrated with PLC, DCS, or dedicated machinery monitoring systems.

Use in Hazardous and Harsh Industrial Areas

Thanks to CSA, ATEX, and IECEx approvals, the 3300 XL 8 mm Reverse Mount Probe is suitable for use in hazardous areas commonly found in oil & gas, petrochemical, power generation, and heavy industrial automation applications. The optional FluidLoc™ cable feature further enhances reliability by preventing oil or process fluids from migrating through the cable, reducing the risk of contamination and unplanned downtime.

Flexible Installation and System Integration

The reverse mount design, 3/8-24 UNF thread, and miniature ClickLoc coaxial connector allow easy installation in tight or restricted mounting locations. With full interchangeability across the 3300 XL transducer system components, the 330105-02-12-10-02-05 3300 XL 8 mm Reverse Mount Probe simplifies system expansion, maintenance, and spare parts management, making it an ideal sensing solution for modern automated machinery monitoring systems.
