The Bently Nevada 330101-00-36-10-01-00 is a 3300 XL 8mm proximity probe featuring a 1.0-meter cable and a 3.6″ threaded case. It delivers high-accuracy vibration and displacement monitoring for critical industrial rotating assets.
The Bently Nevada 330101-00-36-10-01-00 functions as a high-precision, non-contacting sensor designed for the 3300 XL 8mm Proximity Transducer System. This probe measures both static (displacement) and dynamic (vibration) distances by generating an eddy current field that interacts with a target metal surface. By converting these physical changes into a proportional voltage signal, the probe allows the monitoring system to track shaft behavior with sub-milimeter resolution.
Engineers designed this specific probe configuration for applications requiring a standard 3/8-24 UNF threaded body and a 1.0-meter integral cable. The 8mm tip provides a standard linear range of 2.0 mm (80 mils), which remains the global benchmark for monitoring fluid-film bearings. Furthermore, the 3300 XL series offers enhanced thermal stability and a more consistent Scale Factor compared to legacy models, ensuring that data remains accurate even during significant temperature swings within the machine housing.
This proximity probe actively powers predictive maintenance strategies by delivering high-fidelity data to Turbine Supervisory Instrumentation (TSI). Consequently, operators can identify mechanical issues—such as shaft misalignment, rotor imbalance, or bearing degradation—long before they escalate into catastrophic failures. Moreover, the integration of these probes into a 3500 Monitoring System allows for automatic machinery protection, including emergency trip functions.
Primary industrial applications include:
To ensure survival in punishing environments, Bently Nevada utilizes a 304 stainless steel case and a PPS (polyphenylene sulfide) resin tip. This construction creates a hermetic seal that resists the ingress of oil, moisture, and steam. Additionally, the patented ClickLoc connector technology provides a secure, vibration-resistant electrical path. The included silicone boot further seals the connection, ensuring that environmental contaminants do not interfere with the sensitive electrical signals.
The Bently Nevada 330730-080-00-00 functions as a high-precision signal conduit within the 3300 XL 11mm Proximity Transducer System. This specific cable model enables the seamless transmission of displacement and vibration data from the proximity probe to the Proximitor sensor. By maintaining a constant electrical impedance, the cable ensures that the monitoring system captures accurate mechanical data from high-speed rotating assets.
Technicians primarily deploy the 3300 XL 11mm system when an application requires a broader linear range than standard 8mm sensors can provide. Consequently, this extension cable becomes a critical component in monitoring large-scale machinery where shaft movement or clearances are more substantial.

Beyond basic signal relay, the 330730-080-00-00 extension cable actively supports predictive maintenance strategies. By delivering high-fidelity vibration signals, the cable allows the diagnostic system to identify early-stage faults such as bearing wear, rotor imbalance, or shaft misalignment. Furthermore, this proactive data stream helps operators avoid catastrophic mechanical failures and reduces the high costs associated with unplanned downtime.
Specific applications include:
Monitoring axial position and radial vibration in large steam or gas turbines.
Tracking shaft displacement in high-capacity centrifugal compressors.
Providing phase reference signals via Keyphasor integration for speed and timing analysis.
Bently Nevada manufactures the 330730-080-00-00 to withstand the rigorous thermal and chemical conditions found in power plants and refineries. Although this version lacks external armor, the high-quality jacketing material provides excellent flexibility and chemical resistance. Additionally, the patented ClickLoc connectors facilitate a secure, vibration-proof connection. These connectors snap firmly into place, ensuring that electrical continuity remains intact even when the machinery experiences intense high-frequency oscillations.
