The Bently Nevada 330171-00-08-10-02-05 is a 3300 5mm proximity probe designed for high-performance eddy current vibration and position measurement. This transducer is engineered for use in fluid-film bearing machines, Keyphasor applications, and speed monitoring. By utilizing the 3300 XL transducer system, this probe provides an output voltage proportional to the gap between the probe tip and a conductive target surface.

Features

• Patented TipLoc molding method for enhanced mechanical durability.
• Compact 5.2 mm diameter probe tip for installation in constrained spaces.
• Corrosion-resistant gold-plated ClickLoc connectors.
• Maintains a 2 mm (80 mil) linear electrical range consistent with 8 mm systems.
• Optional FluidLoc cable sealing available for liquid containment.

Applications

• Centrifugal and axial compressors.
• Process turboexpanders in cryogenic or gas processing.
• Small steam turbines and industrial electric motors.
• High-speed industrial gearboxes with tight internal clearances.
• Multistage centrifugal pumps.

Technical Specifications

Installation Guidelines

• Side-View Clearance: Maintain a minimum diameter of 15.2 mm (0.60 inches) of clear space around the probe tip centerline to prevent interference.
• Counterbore Clearance: If the probe is recessed, the counterbore diameter must be at least 15.2 mm (0.60 inches).
• Tip-to-Tip Spacing: For dual (X-Y) radial vibration probes, ensure a minimum separation of 40 mm (1.6 inches) for axial or 74 mm (2.9 inches) for radial installations.
• Handling: Handle the probe tip with care to avoid damage to the sensing face. Ensure all connections are clean and fully seated before system power-up.

FAQ

What is the primary function of the 330171-00-08-10-02-05?

This probe acts as an eddy-current sensor to measure dynamic vibration and static position of rotating shafts in industrial machinery.

How does this 5mm probe compare to the 8mm series?

The 5mm probe offers the same 2mm linear range as the 8mm version but in a smaller physical package, making it suitable for applications where space is limited.

What is the scale factor for this system?

The system features a standard incremental scale factor of 7.87 mV/µm (200 mV/mil) when calibrated to a standard AISI 4140 steel target.
