Bently Nevada 330103-00-05-10-10-02-00 3300 XL 8 mm Proximity Probe

Description

Option 00 (0 mm unthreaded) and Option 05 (50 mm overall case length) specify this 3300 XL 8 mm metric proximity probe configuration — 330103-00-05-10-10-02-00. This unarmored, metric thread proximity probe is designed for Bently Nevada 3300 XL proximity transducer systems, functioning on the eddy-current principle to measure static and dynamic shaft displacement on high-speed rotating machinery. Operating with non-contact precision, it is used to measure radial vibration, axial position, and speed when paired with a companion extension cable and 3300 XL Proximitor sensor.

The defining feature of this configuration is its FluidLoc cable (Option 10) combined with a standard miniature coaxial ClickLoc connector (Option 02). The FluidLoc cable incorporates internal sealing compounds that block oil, synthetic lubricants, and process fluids from migrating through the internal wire strands of the coaxial cable, preventing fluid leaks from critical machine casings. Unlike armored sibling models (such as the 330104 series), this unarmored variant provides enhanced coaxial flexibility for installations utilizing dedicated conduit or protected routing trays where mechanical wear risks are minimized.

Features

• M10 x 1 metric thread design for direct mounting into metric-tapped machine casings and brackets.
• Fully threaded 50 mm case length (0 mm unthreaded segment) to offer versatile adjustment depth during sensor positioning.
• FluidLoc cable integration prevents pressurized oil or process gases from leaking along the internal cable pathways.
• 1.0-meter total probe cable length, providing a direct link to standard extension cables or close-proximity terminal boxes.
• Gold-plated ClickLoc miniature coaxial connector secures electrical contact with simple finger-tight torque.
• General unarmored coaxial cable sheath design, reducing mounting profile and enhancing routing flexibility.

Applications

This metric proximity probe is deployed in heavy-industrial environments including oil and gas refining, power generation, petrochemical processing, and maritime propulsion. Typical rotating machinery monitoring applications include radial shaft vibration, axial thrust position, casing expansion, and reference timing (Keyphasor) measurements on turbines, compressors, gearboxes, pumps, and large industrial motors where M10 x 1 threads are standard.

Installation Guidelines

When installing the probe, confirm that the physical mounting bracket or machine casing matches the metric M10 x 1 thread pattern. Ensure the probe gap is adjusted relative to the target shaft (typically set to -10 VDC or approximately 1.27 mm gap for standard 3300 XL systems) before final locknut tightening. Take care during cable routing to maintain a minimum bend radius of 25.4 mm (1.0 in) to prevent coaxial signal deterioration. The ClickLoc connectors must be joined finger-tight; they are designed to click audibly into place without the use of specialized torque wrenches or pliers.
