Configured for vibration and displacement monitoring in 3300 XL Transducer System platforms, the Bently Nevada 330103-00-04-05-02-CN (330103 Proximity Probe) provides direct physical/electrical execution. This metric hardware component establishes a high-frequency radio frequency field at the sensor tip, translating physical proximity gaps between the unarmored 8 mm probe face and a rotating conductive metal shaft into proportional electrical modulation loops without physical contact.
Suffix Breakdown & Model Matrix
- 330103: Base module parameter for the 3300 XL 8 mm proximity probe utilizing an M10 x 1 thread layout without an interlocking armor sheath.
- -00: Unthreaded length option, indicating 0.0 mm of smooth, unthreaded barrel depth.
- -04: Overall case length option, indicating a 40 mm total threaded housing depth.
- -05: Total length option, establishing a 0.5 metre (1.6 feet) integrated cable path length.
- -02: Connector and cable type option, selecting a miniature coaxial ClickLoc connector matched with a standard electrical cable core.
- -CN: Agency approval option, designating country-specific dangerous area markings including regional industrial safety certifications.

Mechanical Monitoring & TSI Technical Attributes
The eddy-current transducer installation requires strict matching to target metallurgy profiles to ensure stable eddy-current probe scaling coefficients across the measurement zone. During field verification, technicians must execute a precise gap voltage validation sequence, mechanically adjusting the probe depth inside the M10 x 1 entry point until the steady-state DC potential registers exactly -10 VDC at the linear center point. This baseline calibration guarantees proper tracking of rapid rotor dynamics and limits physical measurement drift caused by extreme thermal expansion. Cross-talk suppression is maintained by internal coaxial shield density to isolate raw signals from surrounding inductive noise.
Frequently Asked Questions
Q: What physical handling rule prevents calibration shifts at the ClickLoc connection point?
A: The miniature coaxial ClickLoc connector must be engaged and disengaged by hand pressure only. Using mechanical pliers or wire tools permanently warps the internal gold-plated barrel shell, modifying total loop impedance.
Q: Can this 0.5 metre unarmored cable link directly to a remote 3500 monitor rack terminal block?
A: No. The probe is an inductive element requiring a specific 3300 XL extension cable to build out a complete 5.0 or 9.0 metre balanced network matched to the excitation frequency of the host Proximitor Sensor.
Q: How does liquid or oil exposure on the probe tip affect raw output resolution?
A: The polyphenylene sulfide (PPS) tip material is completely non-conductive. Standard non-conductive machine oil coatings do not impact the eddy-current penetration depth or alter the targeted linear tracking.
Field Installation Guidelines
- Clean out the M10 x 1 metric threaded penetration, ensuring the interface is free of residual drilling metal, old sealants, or carbon scale.
- Thread the 40 mm stainless steel probe body into the mounting hole by hand to eliminate cross-threading hazards.
- Hook an external digital multimeter up to the Proximitor loop test points to watch active voltage output during final depth adjustment.
- Rotate the probe barrel slowly until the gap voltage validation matches the baseline index of -10 VDC.
- Lock the external hex nut firmly against the machine structural wall to preserve the verified air gap under constant operating vibration, and seal the coaxial junction against moisture using self-fusing insulation tape.
