Bently Nevada 330101-00-08-05-12-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread, without Armor

330101-00-08-05-12-CN: The CN Approval Designation on a 05 Base

The value of this configuration is that it combines a -05 base with the CN approval designation, which is the pairing used where the installation requires that approval combination. The 05 segment is carried through to the twelfth position, so this is not the same part as either the plain -05- or the plain -CN- variant.

Decoded against the published configuration data: 330101 = 3300 XL 8 mm probe. 00 = 00 position. 08 = 08 position. 05 = 05 position. 12 = 12 position. CN = agency approval CN.

The configuration data that matter operationally on this variant are concrete: thread is 3/8-24 UNF, the probe is supplied without armor, cable length is 0.5 meter, the connector is miniature coaxial ClickLoc, and the cable type is FluidLoc. FluidLoc is the field-splittable cable design, which is what allows a probe with a short 0.5 m cable to be extended at the junction without a spliced joint in the field.

05-Base Variants and Where CN Falls in the Sequence

Within the 05 base family the twelfth position and the final country code are what separate the configurations. Confirming both against the removed probe is what prevents ordering a variant that cannot be installed:

Why the Country Code Is Not a Cosmetic Suffix

On a probe family with several hundred catalogue variants, the trailing country code is part of the ordering identity rather than a label. Manufacturers treat these as distinct orderable configurations with distinct approvals. When replacing a probe in a classified installation, ordering the wrong country code can mean the delivered part does not carry the approval the installation requires, which is a compliance problem rather than a fit problem.

Installation and Gap Verification

Recommended gap on the 3300 XL platform is -9 Vdc, approximately 1.27 mm (50 mils) for radial vibration monitoring. Confirm the thread standard (3/8-24 UNF), case segment, and gap voltage against the machine before energising the monitor channel. The probe seals differential pressure between tip and case with a Viton O-ring and is not field-repairable — if the seal is suspect, the correct remedy is a replacement probe.
