Configured for continuous radial displacement measurement in rotating machinery platforms, the Bently Nevada 330101-00-30-90-02-05 (330101-00-30-90-02-05) Proximity Probe provides direct physical and electrical execution by transforming mechanical air-gap variations into proportional low-level voltage signals.

Hardware Specifications

Rotor Dynamics & Transducer Scaling

The assembly executes eddy-current probe scaling to monitor dynamic and static mechanical gaps between the probe tip and the rotating shaft surface. Continuous gap voltage validation against standard -10 VDC targets confirms proper sensor positioning and electrical bias during active machine operation. Rotor dynamics signals are captured without physical contact, eliminating friction wear under high-speed turbine conditions. Cross-talk suppression properties protect signal integrity when multiple channels operate in close proximity within tight machinery housings.

Ordering Information

• 1 x 3300 XL 8 mm Proximity Probe (Part Number: 330101-00-30-90-02-05)
• 1 x Threaded Mounting Nut and Lockwasher Assembly
• 1 x Technical Instruction Leaflet and Compliance Sheet

Field Installation Guidelines

• Thread the probe assembly into the machine mounting port maintaining a minimum of 5 full thread engagements for structural stability.
• Torque the mounting nuts using calibrated tools while preventing any torsional stress on the coaxial cable connection.
• Route signal cabling away from high-voltage power conduits to eliminate induced electromagnetic interference on the measurement loop.
• Verify that the cable shield drain wire is grounded strictly at the monitor panel termination point to prevent ground loops.

Frequently Asked Questions

• Q: What is the nominal output scale factor for this proximity probe model?
• A: The scale factor is exactly 7.87 V/mm (200 mV/mil) across the linear operating range.
• Q: How does temperature fluctuation affect measurement accuracy?
• A: Integrated thermal compensation limits output drift across the entire -51 deg C to 177 deg C operating envelope.
• Q: What is the function of the -10 VDC gap voltage target during setup?
• A: It aligns the probe operating point to the exact midpoint of its linear voltage response curve.
• Q: Can this component be installed in hazardous industrial zones?
• A: Yes, it includes CSA hazardous area certifications for explosive industrial environments.
• Q: What is the minimum thread engagement required for proper mounting?
• A: Installers must maintain at least 5 full threads of engagement to withstand high machinery vibration.
• Q: Does the probe require an external power supply connection?
• A: No, it operates passively, receiving excitation power directly from the connected Proximitor sensor.
• Q: How should the coaxial connector be protected against moisture ingress?
• A: Connectors must be secured with ClickLock fittings and enclosed within protective junction housings.
• Q: Are extension cables interchangeable across different 3300 XL configurations?
• A: Extension cables must match the specific system capacitance rating required for the 3300 XL platform.
