- Product Introduction & Supply Chain Strategy
The Bently Nevada 330103-00-03-10-02-05 is a 3300 XL series 8mm eddy current proximity probe configured with a 3-inch fully threaded body, 1.0-meter armored cable, ClickLoc connector, and multi-agency explosion-proof ratings. It works alongside a 3300 XL extension cable and Proximitor Sensor to deliver non-contacting shaft vibration, radial position, and axial thrust measurement for turbines, compressors, gearboxes, and large industrial pumps.
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All probes undergo rigorous quality verification to ensure OEM-level reliability. Refurbished proximity probes carry severe risks of micro-cracks in the polyetheretherketone (PEEK) tip, internal cable fatigue, or altered coil inductance, which directly cause false vibration trips or failure to detect shaft contact. Securing this probe as New Surplus guarantees exact 200 mV/mil linear scale output, lowers total cost of ownership (TCO), and eliminates operational risks caused by emergency factory lead times.

- Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Verify machinery is shut down and locked out/tagged out (LOTO) prior to installing probes near shaft journals.
- Inspect the probe tip and cable armor for physical damage. Never bend the coaxial cable tighter than its minimum 25.4 mm (1.0 in) bend radius.
- Ensure target shaft material matches standard AISI 4140 steel calibration (or account for electrical runout corrections).
Stage 2: Removal
- Disconnect the ClickLoc coaxial connector from the extension cable.
- Unscrew the locknut on the probe housing bracket and back out the old probe from the threaded mounting port.
- Clean external threads and mounting faces to remove oil and metal shavings.
Stage 3: Installation (Clone & Seat)
- Thread the new 330103-00-03-10-02-05 probe into the mounting bracket or probe housing.
- Adjust probe gap to center voltage (typically −10.0 V DC gap voltage corresponding to a 1.0 mm / 40 mil physical gap between probe tip and target shaft).
- Tighten external locknut to specified torque (maximum 7.5 N·m / 66 in·lb) to lock mechanical position without stripping casing threads.
- Join the coaxial ClickLoc connectors securely until you feel the mechanical detent click, then slide the connector protector sleeve into place over the junction.
Stage 4: Power-On & Testing
- Measure DC gap voltage across the Proximitor output terminals using a calibrated digital multimeter (DMM).
- Confirm the static reading falls within the normal bias range (−9.0 to −11.0 V DC) before starting the machine.
- Verify dynamic vibration spectrum and amplitude readings on the connected 3500 rack or machinery diagnostic system.
- Firmware/Software Versions & Upgrade Notes
- System Compatibility: 3300 XL 8mm probes are fully backward compatible with legacy 3300 series 8mm proximity systems, provided total electrical length is matched correctly.
- Length Matching Rule: This probe has a 1.0-meter cable length. It MUST be paired with a 4.0-meter extension cable to form a standard 5.0-meter system length, or an 8.0-meter extension cable for a 9.0-meter system length. Mixing length configurations alters the total system inductance and ruins calibration scaling.
- Calibration Note: The probe contains no digital firmware. Output accuracy relies strictly on physical gap geometry, driver supply voltage (−24 V DC), and correct total system cable impedance.
- Frequently Asked Questions (FAQ)
Q: Are these units really brand new, or are they refurbished/repaired cards? A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules feature zero thread wear, zero tip abrasion, intact connector plating, and original anti-static packaging opened only for mandatory QC testing.
Q: Why is New Surplus priced higher than refurbished probes on the market? A: Refurbished probes frequently suffer from compromised internal cable shielding or damaged PEEK tips that cause signal drift. Saving 100 on a used probe can cause a false trip on a 2M turbine generator. Our pricing reflects genuine, factory-fresh inventory that delivers full OEM lifespan and exact electrical linearity out of the box.
Q: What does the -05 Agency Approval option mean on this probe? A: The -05 option indicates multiple hazardous area certifications, including CSA, ATEX, IECEx, and INMETRO approvals for Class I, Division 1 / Zone 0 hazardous locations, allowing installation in explosive gas environments when wired with approved intrinsic safety barriers.
Q: What is the purpose of the flexible armor on this cable option? A: The stainless steel armor jacket shields the delicate internal coaxial cable against mechanical crushing, abrasive wear, hot oil contact, and accidental pinching inside hostile machine environments.
Q: What warranty coverage applies to this module? A: Every 330103-00-03-10-02-05 New Surplus probe comes backed by a comprehensive 1-year replacement warranty, fully verified through physical inspection, continuity/resistance checks, and ESD-safe packaging protocols.
