330106-05-30-90-12-00 Bently Nevada 3300 XL 8mm Probe Guide
330106-05-30-90-12-00 Product Introduction
The 330106-05-30-90-12-00 belongs to the Bently Nevada 3300 XL 8mm proximity probe family. This reverse mount probe delivers precise shaft vibration and displacement measurements. It serves as a key component in the 3300 XL transducer system. The 330106-05-30-90-12-00 uses eddy current technology for non-contacting operation. This eliminates mechanical wear and ensures long-term reliability. The probe works with a Proximitor sensor and an extension cable for a complete monitoring solution.
The part number breaks down into specific configuration codes. The 330106 prefix identifies the reverse mount probe series. The 05-30 segment specifies the M10 x 1 thread with a 30mm case length. The 90 indicates a 9.0-meter total cable length. The 12 designates the miniature ClickLoc coaxial connector with FluidLoc cable. The 00 means no agency approvals are required.
Core Value
The 330106-05-30-90-12-00 provides reliable performance in demanding industrial environments. Firstly, the reverse mount design suits space-constrained installations inside bearing housings. This allows you to monitor shaft movement where standard probes cannot fit. Moreover, the 9.0-meter FluidLoc cable offers flexibility for remote sensor mounting. This reduces the need for additional junction boxes in many cases. The probe tip uses polyphenylene sulfide (PPS) for durability. The case is AISI 303 or 304 stainless steel for corrosion resistance.
Furthermore, the 330106-05-30-90-12-00 supports full interchangeability. You can swap this probe with other 3300 XL 8mm components without recalibration. This saves significant time during maintenance and reduces spare parts inventory. The ClickLoc connector provides a secure, gold-plated connection that resists moisture and oil mist. This ensures signal integrity in harsh environments like turbine decks and compressor stations.
Technical Insights
The 330106-05-30-90-12-00 offers specific electrical and mechanical parameters. Its nominal DC resistance is 9.87 Ω ± 0.50 Ω. The operating temperature ranges from -52°C to +177°C in standard mode. The extended range reaches up to +218°C for the probe tip and +260°C for the cable and connector. The probe withstands high vibration environments with a tensile strength rating of 330N (75 lbf).
The total cable length is 9.0 meters or 29.5 feet. This length is designed for use with the appropriate Proximitor sensor. The electrical length of the probe plus the extension cable must match the Proximitor specification. The M10 x 1 threads engage with a maximum threading depth of 15 mm. The recommended installation torque is 7.5 N•m (66 in•lbf). The maximum rated torque is 22.6 N•m (200 in•lbf). The probe tip diameter measures 8.0 mm or 0.31 inches.
Installation & Maintenance
Proper installation of the 330106-05-30-90-12-00 ensures optimal performance. Begin by verifying the mounting surface is clean and free of debris. Thread the probe into the mounting hole using the M10 x 1 thread. Apply the recommended torque of 7.5 N•m. Do not exceed 22.6 N•m to avoid damage. The reverse mount design installs from the inside of the bearing housing. Therefore, you must access the internal mounting area during installation.
Connect the ClickLoc connector securely to the extension cable. Ensure the connection is dry and free from contaminants. The gold-plated contacts maintain signal quality in oil-mist environments. For maintenance, perform annual inspections of the connector and cable. Check for signs of wear, corrosion, or mechanical damage. Verify the cable routing does not create sharp bends or tension points. The FluidLoc cable option is often unnecessary due to the probe sleeve. Consider your application carefully before ordering this feature. The probe is not pressure tested before shipment. Contact a representative if your application requires custom testing.
