Product Introduction
Reverse-mount probes are specified when the probe must be installed from the rear side of the bracket or when forward access is restricted. The Bently Nevada 330106-05-30-15-02-CN is a 3300 XL 8 mm reverse proximity probe with a 30 mm unthreaded length, 1.5 m integrated probe cable, ClickLoc connector, and multi-license agency approval.
This probe delivers a 2 mm (80 mils) 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 30 mm unthreaded length is the key mechanical differentiator here—this variant is intended for installations where additional standoff distance is required between the mounting threads and the probe tip. As with all Bently Nevada ordering codes, the exact approval drawing and installation constraints should be confirmed from the physical label before commissioning.

Key Selling Points & Differentiators
- 30 mm unthreaded length. This is the defining feature of the 330106 family versus standard reverse probes—provides additional standoff where bracket geometry requires it.
- 1.5 m probe cable. Longer than the common 0.5 m or 1.0 m variants, useful when the ClickLoc connection point sits farther from the bracket.
- Reverse-mount geometry. Enables installation from the rear side of the bracket where forward access is blocked.
- Exact code match. This is the 30 mm unthreaded, 1.5 m, 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.
Quality Transparency SOP
- Part number verification. We confirm the label reads 330106-05-30-15-02-CN and matches the 3300 XL 8 mm reverse probe family.
- Unthreaded length measurement. The 30 mm unthreaded section is verified against the label to ensure it matches the required bracket standoff.
- Cable and connector inspection. The 1.5 m cable jacket, ClickLoc connector, and probe tip are checked for cracks, 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.
- 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 probe cable length before installation. Code “15” means a 1.5 m probe cable. If the original probe was 0.5 m or 1.0 m, this unit may not reach the extension cable without rework, or may create excess slack.
❗ Confirm total system length before installation. This probe has a 1.5 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).
❗ Confirm unthreaded length before installation. Code “30” means 30 mm unthreaded length. If the original probe had a different unthreaded length, this unit may not seat correctly in the bracket.
❗ Do not substitute 330106 for 330105 without checking unthreaded length. Both are 8 mm reverse probes, but the 330106 family carries a defined unthreaded length code (30 mm here), while standard 330105 variants may have different unthreaded configurations.
❗ 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 “CN” 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 reverse probe only. A complete measurement channel also requires a compatible 3300 XL extension cable and 3300 XL proximitor.
Can I replace a 330106-05-30-10-02-05 with this? Not without checking cable length. The -10- variant has a 1.0 m probe cable, while this unit is 1.5 m. Electrically they are similar, but the extra 0.5 m may affect routing and total system length.
Can I replace a 330105-02-12-10-02-05 with this? Not without checking the unthreaded length. The 330105 is a standard reverse-mount probe, while the 330106-05-30-15-02-CN has a 30 mm unthreaded section. Electrically they are similar, but mechanically they may not fit the same bracket.
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, or chemical exposure is not covered.
