The Bently Nevada 330103-01-09-50-02-00, also cataloged as the 330103 Proximity Probes, operates as a dedicated hardware component for eddy-current signal sensing within 3300 XL Transducer System platforms.

Suffix Breakdown & Model Matrix

The 330103-01-09-50-02-00 part number signifies the following hardware configuration:

• 01: Unthreaded length (10 mm).

• 09: Overall case length (90 mm).

• 50: Total length (5.0 meters).

• 02: Connector option (Miniature coaxial).

• 00: Agency approval option (Standard).

Hardware Specifications

Mechanical Monitoring & TSI Integration

The transducer loop is factory-calibrated to a sensitivity of 7.87 V/mm (200 mV/mil) for precise rotor dynamics analysis. During commissioning, gap voltage validation targets of -10 VDC at the Proximitor output are mandatory to ensure the probe resides within the linear region of its sensing range. Maintaining this gap is the primary mechanism for monitoring shaft axial position and radial vibration. Cross-talk suppression is achieved by observing strict spatial separation guidelines between adjacent probe assemblies, which prevents interference from overlapping high-frequency excitation fields in multi-channel monitoring installations.

Field Installation Guidelines

Probe Mounting

• Thread Engagement: Ensure that mounting brackets are clean and allow for a minimum of 5 full thread engagements to ensure mechanical stability.

• Gap Setting: Use a calibrated depth micrometer to adjust the probe tip-to-target distance. Verify the Proximitor signal output matches the nominal -10 VDC setpoint at the monitor rack.

• Torque Protocol: Tighten the locknut to the manufacturer-specified torque value; excessive force may cause permanent deformation of the 303 stainless steel housing.

Cabling and Grounding

• Conduit Protection: The coaxial lead must be enclosed in grounded metallic conduit to provide an electromagnetic shield and protect against mechanical abrasion.

• Grounding: Terminate the probe shield at the instrument cabinet ground bar to prevent the formation of ground loops, which introduce 50/60 Hz noise into the vibration signal.

Logistics and Shipping

• Delivery time: 2-7 days when payment finish.

• Dispatched via DHL/FEDEX/UPS.

• Each unit is sealed in anti-static industrial packaging for maximum protection.

Frequently Asked Questions

• Q: Is this probe compatible with the older 3300 series Proximitor sensors?

• A: No. The 330103 probe is designed specifically for 3300 XL electronics. Interfacing with legacy systems will lead to incorrect scale factors and signal distortion.

• Q: Can I modify the 5.0-meter integral cable length?

• A: No. The cable is a calibrated component of the transducer loop. Any modification to the length changes the system impedance and invalidates the factory calibration.

• Q: What is the primary cause of signal drift in these units?

• A: Signal drift is typically attributed to thermal expansion of the machine casing or a loose mounting locknut. Verify torque settings at every maintenance interval.
