Product Introduction
Reversed-mount probes are often specified when the mechanical housing, bracket geometry, or access path prevents a forward-mount installation. The Bently Nevada 330105-02-12-10-02-05 is a 3300 XL 8 mm reversed proximity probe with a 1.0 m integrated cable, armored construction, ClickLoc connector, and multi-license agency approval.
This probe delivers a 2 mm linear range at approximately 7.87 V/mm (200 mV/mil) sensitivity when paired with a compatible 3300 XL proximitor such as the 330180 series. That makes it suitable for radial vibration, axial displacement, and Keyphasor applications on API 670-style monitoring channels. The armored cable adds mechanical protection in congested turbine, compressor, or gearbox bays, while the ClickLoc connector enables faster, cleaner field termination. As always, the exact approval drawing and installation constraints should be confirmed from the physical label before commissioning.

Key Selling Points & Differentiators
- Reversed-mount geometry. Designed for installations where the probe must be mounted from the rear side of the bracket or where forward access is restricted.
- Armored cable construction. Better mechanical protection than non-armored variants, especially in crowded turbine/compressor bays.
- Exact code match. This is the 1.0 m, armored, ClickLoc, multi-license approval variant—no guessing on length or certification.
- Drop-in 3300 XL compatibility. Works with standard 3300 XL extension cables and 330180-series proximitors without matched-component calibration.
- Clear boundary. Not a 5 mm probe. The 330105-02-12-10-02-05 is an 8 mm reversed probe, so it must not be confused with 5 mm reversed variants or forward-mount 330103 probes.
Quality Transparency SOP
- Part number verification. We confirm the label reads 330105-02-12-10-02-05 and matches the 3300 XL 8 mm reversed probe family.
- Armor and connector inspection. The armored jacket, ClickLoc connector, and probe tip are checked for crushing, corrosion, or pin damage.
- Continuity and insulation check. Using a Fluke multimeter, we verify center conductor continuity and shield integrity from probe end to connector.
- Tip and thread inspection. The probe tip, threads, and reversed-mount body are inspected for scoring, deformation, or chemical damage.
- ESD-safe packing. The probe is coiled to the recommended bend radius, sealed in an anti-static bag, and foam-packed to prevent connector stress.
Technical Risk Avoidance
❗ Confirm total system length before installation. This probe has a 1.0 m cable. The extension cable length must be selected so that probe cable + extension cable equals the proximitor system length (commonly 5.0 m, 7.0 m, or 9.0 m).
❗ Do not substitute 8 mm reversed for 5 mm reversed. Although both use the 330105 family, 5 mm reversed probes have a smaller linear range (~1.5 mm / 60 mils) and different mechanical fit. This unit is an 8 mm reversed probe with a 2 mm linear range.
❗ Verify proximitor compatibility. The probe must be paired with a 3300 XL proximitor calibrated for AISI 4140 steel and the correct system length. Mismatched proximitor models can shift sensitivity and gap-voltage settings.
❗ Confirm the approval drawing for hazardous areas. The “05” code means multi-license approval, but the exact installation requirements—such as temperature class, IP rating, and voltage limits—must be verified against the physical label before commissioning in Zone 2 / Division 2 areas.
Buyer’s FAQ
Is this a complete sensor system? No. This is the 8 mm reversed probe only. A complete measurement channel also requires a compatible 3300 XL extension cable and 3300 XL proximitor.
Can I replace a 330105-02-12-05-02-05 with this? Not without checking length. The -05-02-05 variant has a 0.5 m probe cable, while this unit is 1.0 m. Electrically they are similar, but the extra cable length may affect routing and total system length.
Can I replace a 330103-00-05-10-02-00 with this? No. The 330103 is a forward-mount 8 mm probe, while the 330105-02-12-10-02-05 is a reversed-mount 8 mm probe. They are not mechanically interchangeable without bracket reconfiguration.
Does this include the extension cable and proximitor? No. Unless explicitly stated, this listing covers the probe only. Extension cable and proximitor are separate line items.
Is this genuine Bently Nevada? Yes. We sell genuine surplus inventory. The part number is verified against the physical label before dispatch. No clones or rebuilt substitutions.
What warranty applies? Standard 12-month warranty against DOA and functional defects. Mechanical damage from incorrect installation, gap setting, oil ingress, or cable crushing is not covered.
