Description
Optimized for dynamic machinery protection and diagnostic testing, the Bently Nevada 330101-00-36-10-02-CN eddy current proximity probe delivers high-accuracy non-contact displacement measurements. This probe is a critical sensor component within the industry-standard 3300 XL 8 mm Series, engineered to monitor radial vibration, axial thrust position, and keyphaser reference signals on critical rotating assets such as steam turbines, centrifugal compressors, and heavy industrial pumps.
The system relies on a rugged Polyphenylene Sulfide (PPS) tip mold chemically bonded to an AISI 303/304 stainless steel case, ensuring absolute sealing against oil, water, and synthetic lubricants. By leveraging the advanced ClickLoc miniature coaxial connector, the system guarantees a stable, moisture-resistant signal path to the Proximitor sensor, eliminating common field connection signal losses and keeping installation time to a minimum.

Empirical Engineering Insights
Alternative Models & Compatibility
This probe works strictly within the 3300 XL series architecture. Ensure that the total system electrical length (probe cable + extension cable) equals 5.0 meters or 9.0 meters depending on the specific model of your 3300 XL Proximitor Sensor. Mixing non-XL components with 3300 XL components will cause scale factor mismatch errors.
Application Pitfalls & Engineering Notes
Because this model has an unthreaded length option of 00 (0.0 inches), the threads run completely to the end of the metal housing. During installation inside internal brackets, watch for thread galling. Using low-tolerance mounting sleeves can damage the threaded case and block clean access to target areas.
Commissioning & Wiring Tips
Always use a physical calibration spindle to set your probe gap rather than relying purely on digital voltage readings. Ensure the miniature ClickLoc coaxial connections are completely dry before sliding on the outer protective rubber boot. Moisture ingress in the connector area is the primary cause of signal drift on high-frequency machines.
Installation Guidelines
CRITICAL WARNING
De-energize all machinery and control cabinets prior to probe installation or replacement. Failure to de-energize can lead to electrostatic discharge damage to the Proximitor sensor or trigger false trip signals on safety-instrumented protection relays.
1
Clean the machine casing mounting port thoroughly to remove all oil varnish and metallic burrs before inserting the probe.
2
Carefully thread the probe housing into the mounting port by hand to avoid cross-threading. Do not exceed the maximum installation torque rating of 33.9 N-m (300 in-lb).
3
Connect the 1.0 meter standard cable to the matching 3300 XL extension cable. Push the ClickLoc connector components firmly together until you feel the clean mechanical click locking action.
