Features
- Leak-Proof FluidLoc Protection: Integrates a specialized FluidLoc cable matrix that blocks lubricating oil and process fluids from leaking out of the machine housing through the cable interior.
- Extended Threaded Housing: Formed with a 5.5-inch fully threaded case length and zero unthreaded section, optimizing engagement and mechanical reach in thick-walled machinery configurations.
- High-Strength Cable Interface: Employs a patented CableLoc hardware design providing 330 N (75 lbf) pull strength to prevent separation between the probe lead and tip.
- Robust Molecular Tip Bonding: Utilizes the proprietary TipLoc molding method to forge a robust, impact-resistant bond between the polyphenylene sulfide (PPS) tip and the steel body.
- Finger-Tight Coaxial Joints: Incorporates corrosion-resistant, gold-plated ClickLoc connectors that establish a secure mechanical lock with finger torque alone.
- Connector Protective Boot: Shipped with a pre-installed fluorosilicone connector protector to maximize environmental sealing and shield against moisture ingress out of the box.
System Compatibility & Alternatives
- System Compatibility: This probe is fully compatible with the Bently Nevada 3300 XL Proximitor Sensor (e.g., 330180) and 3300 XL Extension Cables. Because its integrated lead cable length is ultra-short (0.5 meters), it must be paired with a 4.5-meter extension cable to complete a standard 5.0-meter system loop calibration. It is physically and electrically interchangeable with legacy, non-XL 3300 series 5mm and 8mm hardware components compliant with API 670 metrics.
- Alternative Model: 330102-00-55-05-11-00
- Difference from Alternative: The 330101 design is built without armor, utilizing a standard 75Ω triaxial fluoroethylene propylene (FEP) insulated cable that remains thin and flexible for routing through tight internal conduits. The alternative 330102 model is built with armor, which encapsulates the raw FEP cable inside a flexible stainless steel protective sleeve and a rugged outer jacket to guard against direct physical impact and cutting hazards.
Functions
- Dynamic Vibration Transduction: Continuously measures high-frequency shaft motion (0 to 10 kHz frequency response) inside fluid-film bearings to detect structural unbalance, component misalignment, and mechanical looseness.
- Static Displacement Tracking: Monitors slow, static changes in shaft position to provide precise rotor axial thrust readings, preventing catastrophic internal contact between the rotor and stator elements.
- Non-Contact Distance Measurement: Emits a continuous high-frequency electromagnetic field from its 8mm tip to determine the gap distance relative to a conductive metal surface without making physical contact.
- Fluid Leak Mitigation: Prevents lubricating oils and high-pressure vapors from migrating out past the machine casing along the cable voids via its specialty FluidLoc core barrier.
