The Bently Nevada 330104-00-17-05-02-00, also cataloged as the 330104 Proximity Probe, operates as a dedicated hardware component for non-contacting vibration and displacement measurement within 3300 XL platforms. The probe measures proximity changes between its tip and a target shaft via eddy-current field generation, outputting a dynamic analog raw voltage signal routed to an external proximitor processing circuit.

Machinery Monitoring and TSI Characteristics
This eddy-current probe relies on definitive scaling parameters to maintain loop accuracy across variable machine speeds. Field installation requires rigorous gap voltage validation to ensure the sensor tip operates precisely at the center of the linear calibration slope. Transducer loops are adjusted to target a baseline bias voltage of -10 VDC during structural alignment, allowing symmetric tracking of peak-to-peak rotor dynamics. Furthermore, cross-talk suppression must be evaluated when positioning adjacent sensors, preventing mutual high-frequency inductive interference between nearby channels.
Frequently Asked Questions
Q: What are the integration criteria regarding the total loop length of this 0.5-meter probe?
A: The 3300 XL 8 mm proximity system requires a total electrical length of either 5.0 meters or 9.0 meters. Because this probe option provides an integrated 0.5-meter cable, it must be matched with an extension cable of exactly 4.5 meters or 8.5 meters to avoid distorting the standard calibrated scale factor.
Q: How does the FluidLoc option affect physical isolation within the probe assembly?
A: The FluidLoc feature acts as an internal block that prevents oil, process lubricants, or other hazardous liquids from wicking through the core of the coaxial cable line. This maintains electrical performance and containment isolation even if the outer jacket experiences damage or degradation.
Field Installation Guidelines
- Mechanical Casing and Thread Engagement: Inspect the probe mounting threads before physical installation. Hand-thread the 170 mm case into the mounting bracket or sleeve to avoid cross-threading, and lock the final position securely using a calibrated torque wrench on the locknut assembly to resist machine casing vibrations.
- Connector Protection and Grounding Isolation: Clean the ClickLoc coaxial connection interface before matching. The connection must be completely isolated from the metallic conduit and junction boxes using specialized boots or self-fusing tape to eliminate stray ground loop currents.
- Cable Routing and Mechanical Protection: Maintain a strict minimum physical bend radius of 25.4 mm (1.0 inch) along the cable run. Route the standard cable away from structural pinch points and high-temperature manifolds to prevent core dielectric shifting or loss of shielding continuity.
