Features:

  • Flexible Stainless Steel Armored Protection for Maximum Resilience
  • Patented TipLoc™ High-Strength Bonding and Fluid-Tight Seal
  • Gold-Plated ClickLoc™ Connector Interface with CableLoc™ Strain Relief
The rugged coaxial cable of the Bently Nevada 330102-20-55-10-02-00 is entirely encased within a heavy-duty, flexible AISI 302/304 stainless steel (SST) armor conduit. This robust protective layer serves as an impenetrable shield, effectively eliminating common field hazards such as mechanical slicing, sharp-edge shearing, accidental crimping, and physical crushing during aggressive installation. Furthermore, it isolates the critical signal pathway from hostile environmental exposures—including abrasive dust, fly ash, and caustic chemical splashing—ensuring uninterrupted signal transmission even when routed through the most punishing plant conditions.

Engineered to withstand the extreme pressures and turbulent fluid dynamics inside industrial bearing housings, the Bently Nevada 330102-20-55-10-02-00 utilizes Bently Nevada’s patented TipLoc™ molding technology. This advanced manufacturing process creates an unbreakable, molecular-level bond between the high-performance polyphenylene sulfide (PPS) probe tip and the AISI 303/304 stainless steel case. By preventing tip shear and structural delamination caused by thermal cycling or mechanical stress, this design guarantees an absolute, hermetic seal against high-pressure lubricants and synthetic turbine oils, preventing oil migration up through the probe assembly.

The Bently Nevada 330102-20-55-10-02-00 features a premium, corrosion-resistant miniature coaxial ClickLoc™ connector system designed for rapid, error-free field connections. Its positive-locking mechanism provides clear audible and tactile feedback when a secure lock is achieved, eliminating the risk of connection loosening driven by high-frequency machinery dynamics. This gold-plated interface ensures optimal electrical conductivity and zero signal attenuation. For added durability, it is backed by the patented CableLoc™ design, providing a phenomenal 330 N (75 lbf) of cable-to-case pull strength to survive accidental tension over-pulls by technicians.

The 330102-20-55-10-02-00 Bently Nevada 3300 XL 8mm Proximity Transducer Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the required Proximitor Sensor pairing for the Bently Nevada 330102-20-55-10-02-00 to maintain accurate calibration?
The Bently Nevada 330102-20-55-10-02-00 is a 1.0-meter probe and must be paired with a 3300 XL Proximitor Sensor and Extension Cable to form a complete 5-meter or 9-meter system. For example, if configured for a 5-meter system, the Bently Nevada 330102-20-55-10-02-00 must connect to a 4.0-meter extension cable and a 5-meter Proximitor Sensor to output the precise 200 mV/mil scale factor.
Does the Bently Nevada 330102-20-55-10-02-00 support standard Modbus or PROFIBUS protocols directly from the probe?
No, the Bently Nevada 330102-20-55-10-02-00 outputs a raw, high-frequency analog eddy-current signal via its ClickLoc™ connector. Protocol integration occurs downstream when the probe is wired through a 3300 XL Proximitor into a machinery monitoring system like the Bently Nevada 3500, which provides digital interfaces such as Modbus TCP/RTU or Profibus for PLC/DCS integration.
What are the diagnostic indicators when troubleshooting a faulted Bently Nevada 330102-20-55-10-02-00 system loop?
Deep loop diagnostics for the Bently Nevada 330102-20-55-10-02-00 are performed by measuring the DC gap voltage at the Proximitor monitor terminals. A normal operational gap voltage sits between -1.0 Vdc and -17.0 Vdc. If the voltage clips near 0 Vdc or goes to the power supply limit (-24 Vdc), it indicates a short circuit or an open circuit in the Bently Nevada 330102-20-55-10-02-00 cable or connector.
Can the Bently Nevada 330102-20-55-10-02-00 be integrated with third-party condition monitoring hardware?
Yes, the Bently Nevada 330102-20-55-10-02-00 can be integrated with third-party diagnostic systems, provided the third-party monitor can supply a stable -24 Vdc excitation power and read the standard -18 Vdc analog range processed by the accompanying 3300 XL Proximitor sensor.
Can the Bently Nevada 330102-20-55-10-02-00 be installed in ATEX/IECEx Zone 0 hazardous locations?
The specific model code Bently Nevada 330102-20-55-10-02-00 ends with the -00 suffix, which designates "Agency Approvals: Not Required." If your installation requires intrinsic safety certifications (such as ATEX/IECEx Zone 0), you must order the -05 suffix variant rather than this standard industrial Bently Nevada 330102-20-55-10-02-00 unit.
