Bently Nevada 330106-05-30-10-12-05 Probe

3300 XL 8mm Reverse Mount Proximity Probe

Product Introduction

The 330106-05-30-10-12-05 is a factory-configured member of the Bently Nevada 3300 XL 8 mm reverse mount probe family. This sensor performs non-contact measurement of shaft vibration and axial position on rotating machinery. Its M10x1 thread suits compact mounting sleeves where space is limited. Meanwhile, the 1.0-meter total length keeps cable routing short and tidy inside the machine casing. The miniature ClickLoc coaxial connector links directly to standard 3300 XL extension cables and Proximitor sensors.

Technical Specifications

The 330106-05-30-10-12-05 works as a passive eddy-current sensor. It pairs with a compatible 3300 XL Proximitor to produce the standard system output of about -200 mV/mil (7.87 mV/µm).

Specifically, the nominal DC resistance from center conductor to outer conductor is 7.59 Ω ± 0.50 Ω at the 1.0-meter length. The probe tip uses polyphenylene sulfide (PPS), while the case is AISI 303 or 304 stainless steel. The cable is a 75 Ω triaxial design with fluoroethylene propylene (FEP) insulation.

The "12" connector option adds a FluidLoc cable. This feature resists fluid ingress along the cable jacket. Bently Nevada notes that the FluidLoc option is unnecessary for most 330105 and 330106 installations because the probe sleeve already provides sealing. Therefore, confirm your application before selecting this variant.

Mechanical and Environmental Parameters

The probe case uses an M10x1 thread with a maximum thread engagement of 15 mm. Maximum rated tensile strength is 330 N (75 lbf) from probe case to probe lead, and 270 N (60 lbf) at the extension cable connectors. Connector contacts are gold-plated brass or gold-plated beryllium copper for stable signal transfer.

Additionally, the standard operating and storage range is -52°C to +177°C (-62°F to +350°F). Avoid exposure below -34°C (-30°F), since cold shock can cause premature failure of the pressure seal. The probe also shows less than a 3% change in Average Scale Factor after 56 days at 93% relative humidity, tested to IEC standard 68-2-3.

Installation Guide

First, confirm the target material and set the correct gap voltage with a compatible 3300 XL Proximitor. Next, thread the probe cable-end first into the M10x1 mounting sleeve until it touches the target surface, then back it out to the desired gap. The reverse mount layout helps here, because the integral hex nut allows adjustment without twisting the cable. After that, connect the ClickLoc plug to the extension cable and hand-tighten the coupling. Finally, route the cable away from high-voltage lines and variable frequency drives to reduce electrical noise.

FAQ

Q1: What does the "10" in the model code mean?
A: The "10" sets the total length option. On this probe, the cable measures 1.0 meter (3.3 feet).

Q2: Is the FluidLoc cable option required for normal installations?
A: Usually no. Bently Nevada states that the probe sleeve already seals most 330105 and 330106 installations, so the FluidLoc option is rarely necessary.

Q3: Which thread size does this probe use?
A: The 330106-05-30-10-12-05 uses an M10x1 thread with a maximum engagement length of 15 mm. This suits compact sleeves and tight mounting spaces.

Q4: Can this probe operate in hazardous areas?
A: Yes. The "05" agency approval option covers CSA, ATEX, and IECEx certifications for classified locations.

Q5: What is the nominal DC resistance of this probe?
A: At the 1.0-meter length, the nominal resistance from center conductor to outer conductor is 7.59 Ω ± 0.50 Ω.
