330101-XX-XX-10-02-05 MOD 147773-00-12 Bently Nevada 3300 XL 8mm Proximity Probe

A: The 330101-XX-XX-10-02-05 is part of the Bently Nevada 3300 XL 8 mm proximity probe line. In most cases it shows up in rotating machinery protection setups rather than standalone measurement. You’ll find it around API 670 machinery protection systems, steam turbines, gas turbines, centrifugal compressors… basically the usual critical rotating equipment. What it ends up doing is shaft monitoring work — radial vibration, axial thrust position, and sometimes eccentricity when the machine starts behaving slightly off.

A: That part is the mechanical sizing side of the probe. One XX is the unthreaded section, the other is the threaded case length. Nothing electrical there, just physical fit. So 330101-XX-XX-10-02-05 is not a fixed geometry item. It depends on the machine housing depth and how the probe needs to sit in the bore. Usually this is where people double-check drawings before ordering, because once it’s wrong, it’s not really adjustable in the field.

A: That suffix is basically factory-defined.

10 gives you a 1.0 meter integrated cable
02 means ClickLoc connector, gold-plated type
05 covers ATEX, IECEx, and CSA approvals for hazardous areas

So once you land on 330101-XX-XX-10-02-05, those parts are already fixed. No real variation there.

A: Working range sits roughly between 0.25 mm and 2.3 mm, about 10–90 mils, with sensitivity around 7.87 V/mm. It pairs with 3300 XL Proximitor modules and extension cables, then feeds into Bently Nevada 3500/40M or 3500/42M systems. In practice it’s just one of those standard pieces inside a full 3500 monitoring chain for turbines and compressors, nothing isolated.
