330104-00-10-10-02-00 | Bently Nevada | 3300 XL 8mm Proximity Probe

Product Overview

The Bently Nevada 330104-00-10-10-02-00 operates as a high-precision, non-contact eddy current sensor within the industry-standard 3300 XL 8mm proximity transducer platform. This heavy-duty hardware transducer measures static shaft position, axial thrust, and dynamic radial vibration on critical rotating assets, including high-pressure steam turbines, heavy centrifugal fans, and industrial gearboxes.

The probe tip projects a continuous high-frequency electromagnetic field toward the target shaft, reading micro-inch changes in gap distance with absolute precision. This continuous data stream allows plant operators to detect mechanical anomalies like shaft imbalance or bearing wear before structural damage happens. We supply this mission-critical hardware exclusively as a 100% brand new, original factory-sealed unit, which guarantees an unblemished Polyphenylene Sulfide (PPS) tip, untouched gold-plated coaxial contact pins, and pristine factory-stamped calibration profiles.

Engineering Advantages

• Optimizes Depth Positioning via a 100mm Fully Threaded Barrel: The 100 mm continuous thread design (10 case length with 00 unthreaded length) allows installers to fine-tune the depth orientation inside thick-walled bearing caps. This extended threading gives technicians the flexibility to position the probe tip at the exact linear voltage sweet spot without ordering custom brackets.

• Secures Electrical Continuity via ClickLoc Coaxial Connectors: The miniature coaxial interface utilizes a specialized locking ring mechanism. This design resists persistent machinery vibrations and high-frequency resonance inside the fluid housing, preventing the cable connection from rattling loose and avoiding false machine trips.

• Resists Thermal Fatigue at High-Speed Rotor Housings: The glass-filled PPS tip material withstands severe thermal cycling and exposure to hot synthetic lubricants. The chemical-resistant tip maintains its shape and structural integrity under constant pressure and high temperatures, ensuring reliable gap measurements over years of operation.

FAQs

• What total electrical system length does this 1.0-meter probe require?

  The 330104-00-10-10-02-00 includes an integrated 1.0-meter cable (Option 10). To maintain the required 200 mV/mil scale factor, the overall system must measure exactly 5.0 meters or 9.0 meters. Therefore, technicians must connect this probe to either a 4.0-meter or an 8.0-meter extension cable before routing the signal to the final 3300 XL Proximitor sensor block.

• How should technicians set the physical mechanical gap during a live installation?

  Technicians must monitor the DC gap voltage using a digital multimeter hooked up to the Proximitor sensor output terminals while installing the probe. Thread the probe slowly into the mounting port until the multimeter registers approximately -10.0V DC, which represents the precise midpoint of the 2.0 mm linear operating range. Once set, torque the exterior locknut to the factory specification to lock the barrel in place.

• Why must installers avoid running this probe close to surrounding side metals?

  The eddy current field radiates outward from the 8mm tip in a distinct conical shape. If you insert the probe into a narrow mounting hole with insufficient side clearance, the surrounding metal walls will intersect the electromagnetic field, causing cross-talk and distorting the linearity of the output. Maintain a clear radial air gap of at least 3 times the probe tip diameter (24 mm) to prevent edge distortion errors.
