Description
The Bently Nevada 330101-00-28-90-02-00 is a standard 3300 XL 8 mm proximity probe designed for continuous vibration and displacement monitoring on fluid-film bearing machinery. It utilizes eddy-current transducer principles to measure both static (shaft position) and dynamic (vibration) parameters relative to a conductive target.

Engineering and Integration Context
When deploying or replacing proximity probes like the 330101-00-28-90-02-00 in turbomachinery applications, strict mechanical and electrical guidelines must be observed.
- System Matching: The 3300 XL system relies on calibrated component matching. Ensure that the extension cable and Proximitor sensor are calibrated for the exact system length (9.0 meters total system length in this configuration) to maintain measurement linearity and frequency response.
- Mounting and Gapping: The probe requires a minimum shaft diameter of 50.8 mm (2.0 inches) and a minimum flat target size of 15.2 mm (0.6 inches) to prevent edge effects. Use a digital multimeter or Bently Nevada test kit to verify the initial set-point voltage (typically -10 V DC nominal within the linear operating range) during gapping.
- Connector Handling: ClickLoc connectors feature a specialized locking mechanism that produces an audible click. Hand-tighten these connections to ensure proper electrical continuity, and protect exposed connectors from moisture and oil ingress using heat-shrink tubing or rated environmental boots if installed in harsh areas.
Frequently Asked Questions
Q: Can this 9.0-meter probe be used directly with a Proximitor sensor without an extension cable?
A: No. The total system length option (90 designates 9.0 meters) incorporates the matched electrical length of the probe cable combined with an extension cable to reach the Proximitor sensor. Component lengths must sum correctly to match the specific Proximitor sensor calibration (typically 5-meter or 9-meter total system configurations).
Q: Does changing the probe length require recalibrating the monitoring system?
A: The 3300 XL design allows complete interchangeability of system components without individual bench calibration, provided the total system length (probe plus extension cable) matches the Proximitor sensor calibration type (e.g., 9-meter systems). Always verify system rev tags and rack configuration settings.
