Bently Nevada 330104-00-06-90-02-00 3300 XL 8mm Proximity Probe 9.0m 3/8-24 UNF

The Bently Nevada 330104-00-06-90-02-00 is a 9-meter system configuration within the 3300 XL 8mm proximity probe series, designed specifically for machinery installations requiring extended reach and heavy-duty mechanical protection. While it caters to long-distance routing through its specialized cable structure, the series also accommodates standard direct-connection requirements via alternative configurations like the 330102-40-70-10-02-00 and 330102-30-65-10-02-00 models, which offer fixed cable lengths for tighter spatial constraints. Together, these variants deliver precise, non-contacting vibration and position measurements that comply with API 670 standards, ensuring continuous and reliable condition monitoring across diverse industrial rotating equipment.

Note:
Thread Matching: Never force mismatched threads between imperial and metric probe bodies and mounting holes.If the machine's opening is metric, forcibly installing an imperial probe will cause the threads to be ruined.
Cable length mechanism differences:

• -10 (1.0 meter): Requires an extension cable (such as the 330130 series) to form a 5-meter or 9-meter system for connection to the proximitor sensor.
• -90 (9.0 meter): No extension cable required; the probe comes with a built-in 9-meter cable for direct connection to the 9-meter 3300 XL proximitor, reducing one intermediate connector point and lowering the failure rate.

The Bently Nevada 330104-00-06-90-02-00 is a 3300 XL 8 mm Proximity Probe featuring a 9.0-meter total length option (-90-).
To ensure precise vibration and displacement measurements, this probe must be configured within a standard Bently Nevada 9-meter system setup. The hardware matching requirements are defined below:

Compatible Proximitor Sensor (Required)

• Recommended Models: 330180-90-05 (with Multi-Agency Approvals) or 330180-90-00 (Standard/No Approvals).
• Selection Rule: You must select a Proximitor with the "-90-" system length option (9-meter system length) to ensure proper impedance and calibration matching with this 9.0m probe.

Extension Cable Requirement (Not Needed)

• Requirement NONE.
• Technical Note: Because this specific probe comes with an integrated, full-length 9.0-meter cable, it connects "directly" into the 330180-90-XX Proximitor sensor. "Do not add an extension cable to this setup." Interfacing any additional cable will alter the electrical impedance, leading to signal distortion and faulty measurement data on your monitoring system.

📦 Frequently Bought Together (Cross-Selling)

Maximize your system reliability by replacing the core components together. We recommend pairing this probe with:

• Bently Nevada 330180-90-05 | 3300 XL Proximitor Sensor (9.0m System)
• Bently Nevada 21000 | Aluminum Proximitor Sensor Housing / Junction Box

⚠ Important Purchasing Note

Please verify your existing field installation specifications before placing an order. If your control loop layout requires a shorter probe (e.g., 0.5m or 1.0m) paired with a separate extension cable to reach a total length of 9 meters, this integrated 9.0m model will not be the correct fit.

• Thread Standards: The 330102 series utilizes imperial mounting (3/8-24 UNF), whereas the 330104 series is built with metric threading (M10×1).
• System Length & Cable Options: The 330102 configurations in the table are designed for standard 5.0-meter system lengths requiring a separate extension cable, while the 330104-00-06-90-02-00 features a 9.0-meter integral cable designed for direct connection to the Proximitor sensor without an extension cable.
• Physical Case Dimensions: The 330102 variants feature longer mechanical case options (6.5 inches and 7.0 inches) for deep-bore machinery mounts, compared to the compact 60 mm case length of the 330104 metric variant.

Gap Voltage Setup:

• Use a digital multimeter across the Proximitor sensor output terminals (COM and OUT) to measure the DC bias voltage during installation.
• Adjust the standard installation gap voltage to -9.0 VDC to -10.0 VDC (corresponding to a physical gap of approximately 1.27 mm / 50 mils) to ensure the positive/negative 1.0 mm axial/radial dynamic measurement range remains within the optimal linear region.

Probe Clearance Requirements:

• Side-view clearance: Keep a minimum distance of 15.2 mm (0.6 in) clear of any non-target metal structures surrounding the probe tip to prevent eddy current shunting and interference.
• Cross-talk prevention: When installing orthogonal X/Y probes in the same bearing housing, ensure the center-to-center distance between the two probe tips is greater than 40 mm (1.6 in).
• Mounting Torque: When threading the probe into the mounting hole, tighten it securely to maintain proper mechanical stability while avoiding excessive torque that could damage the probe threads or tip.
• Minimum Bend Radius: Ensure the stainless steel armored coaxial cable respects the manufacturer's minimum bending radius limits during field routing to prevent internal conductor damage or characteristic impedance alteration.

ClickLoc Connector Protection:
The integrated ClickLoc coaxial connectors feature a locking mechanism, but in heavy oil mist or high-humidity environments, it is strongly recommended to use a Connector Protector sleeve (PN 40164-01) to prevent oil ingress and signal attenuation.

 

Important Notes for Troubleshooting & Maintenance:

1. Safety Precautions: Ensure power to the monitoring system and Proximitor sensor is disconnected or appropriate safety procedures are followed before performing any physical wiring inspections, resistance measurements, or component replacements.
2. System Calibration Verification: Whenever a component (such as the probe, extension cable, or Proximitor sensor) is replaced, verify the overall system calibration and electrical output to ensure measurement accuracy is maintained.
3. Component Matching Integrity: Never mix or alter component system lengths (e.g., combining 5-meter and 9-meter components) during troubleshooting replacements, as this will cause severe impedance mismatch and calibration errors.

High-Speed Centrifugal Compressor Radial Vibration Monitoring (Part Number Focus: 330104-00-06-90-02-00):

• Application Scenario: Installed directly on high-speed industrial compressors running in continuous petrochemical processing units, where precise shaft dynamic tracking is critical under high-pressure gas loads.
• Core Component & Advantage Integration: Utilizing the 3300 XL 8 mm probe tip and ClickLoc shielded coaxial connection, the system delivers exceptional high-frequency response and noise immunity. This allows operators to capture sub-synchronous vibration and oil whirl phenomena accurately before mechanical degradation compromises compressor integrity.

Heavy-Duty Gas Turbine Thrust & Axial Position Protection (Part Number Focus: 330104-00-20-10-02-00):

• Application Scenario: Deployed in heavy-duty gas turbine trains to measure continuous axial rotor movement relative to the machine casing during high thermal ramp-up and load-shedding cycles.
• Core Component & Advantage Integration: Backed by the factory-calibrated Proximitor sensor linear range (0 to 2.0 mm / 80 mils) and dependable -9 VDC to -10 VDC gap voltage tuning, the loop ensures stable, drift-free axial position measurement. It provides immediate interlock trips to prevent catastrophic thrust bearing wipeout during rapid thermal expansion.

Multi-Unit Rotating Machinery Train Integration:

• Application Scenario: Implemented across complex multi-stage gearboxes, large pumps, and motor-driven compressor trains where varying physical distances between the machinery casing and the junction boxes require specific extension cable routing lengths (utilizing compatible variants such as 330102-40-70-10-02-00 and 330102-30-65-10-02-00).
• Core Component & Advantage Integration: By matching the system length codes precisely across components, these variants maintain identical electrical impedance and scale factors (7.87 V/mm / 200 mV/mil). This ensures seamless signal transmission over extended routing paths without introducing attenuation, phase shift, or calibration errors in harsh industrial environments.
