Description
The Bently Nevada 330105-02-12-10-02-00 is an 8 mm eddy-current proximity probe belonging to the 3300 XL transducer series. It measures static gap distance or high-frequency dynamic shaft vibration on critical rotating machinery like compressor shafts, gearboxes, and steam turbines. Plant instrument crews thread this probe directly into machine housings to establish non-contact displacement monitoring. Are you experiencing strange voltage cutouts or erratic calibration readings on an active vibration loop? This specific configuration features a 1.0-meter total electrical cable length, meaning it must be paired with a 4.0-meter extension cable to properly match a standard 5.0-meter Proximitor sensor module—otherwise, your 200 mV/mil output scale factor will become non-linear.

Cross-Border Logistics and Export Compliance Management
Shipping precision industrial asset protection hardware requires strict compliance with international trade frameworks. We coordinate daily prioritized express air freight shipments via DHL, FedEx, and UPS to streamline physical deliveries to industrial plants across North America, Europe, Australia, and Asia-Pacific.
For international customs classification, this probe falls under HS Code 9031.80.80 (or country-specific tariff variations for electronic non-contact measuring instruments). The complex string of dash options (-02-12-10-02-00) determines the physical physical sizing parameters; don’t worry about destination customs holding your package over these sub-options, provided your shipping documentation and export declarations map out the complete model identifier exactly. Our trade compliance specialists generate all electronic export manifests and itemized commercial invoices to ensure clean passage through customs border checkpoints.
Bently Nevada 8 mm Proximity Probe Field FAQ
- Can I use a standard wrench to tighten this probe during installation?
Well, technically yes, but you must exercise extreme caution. In our field experience, over-torquing a 3/8-24 UNF probe body inside a housing will stretch the internal coaxial bond or crack the PPS tip bonding point. Always use a calibrated torque wrench and never exceed the maximum mechanical limit of 11.2 N·m.
- What is the purpose of the “02” connector protector option?
The integrated connector protector is a specialized sleeve that slides over the ClickLoc coaxial connection joint. It prevents synthetic lubrication oils, cutting fluids, and moisture from seeping into the connector threads, which would alter the electrical impedance profile and trigger false high-vibration spikes on your monitor rack.
