Bently Nevada 330104-00-06-10-01-CN 3300 XL 8 mm Proximity Probe

Description

Engineered for precise non-contact shaft vibration and displacement measurements, the Bently Nevada 330104-00-06-10-01-CN is a heavy-duty 3300 XL 8 mm proximity probe configured for critical industrial machinery monitoring. Utilizing advanced eddy current measurement principles, this probe delivers high-resolution static and dynamic measurements of shaft movement in harsh operating conditions.

This specific configuration features a reverse-mount design with a 3/8-24 UNF thread, providing direct compatibility with standard industrial mounting arrangements. The probe tip is molded from high-durability polyphenylene sulfide (PPS) to withstand extreme thermal and chemical environments, while the probe body is encased in AISI 303 or 304 stainless steel. An integrated Viton O-ring provides a robust seal to handle differential pressures between the probe tip and case. Terminated with a ClickLoc miniature coaxial connector and a standard 1.0-meter cable, this unit integrates seamlessly with 3300 XL Series Proximitor Sensors to supply critical feedback to vibration monitoring and turbine supervisory instrumentation systems.

Features

• Rugged Reverse-Mount Design: Designed with a standard 3/8-24 UNF thread structure for secure back-mounting on machine casings.
• Viton O-Ring Sealing: Built-in sealing mechanism designed to withstand differential pressure between the probe tip and case.
• Premium Metallurgy: Case fabricated from AISI 303 or AISI 304 stainless steel to protect against mechanical wear and chemical exposure.
• ClickLoc Coaxial Connection: Gold-plated miniature coaxial connector features a positive-locking mechanism to prevent accidental disconnection.
• Broad Chemical Resistance: Polyphenylene sulfide (PPS) probe tip offers superior resistance to corrosive process fluids and synthetic lubricants.

Applications

• Steam and gas turbine shaft vibration monitoring.
• Centrifugal and axial compressor displacement measurements.
• Industrial pump and gearbox shaft position tracking.
• Hydroelectric generator air gap and thrust measurements.
• Rotating machinery speed and phase reference sensing (Keyphasor applications).

Installation Guidelines

• Sensor Calibration: Ensure the probe is paired with a matching 3300 XL 8 mm Proximitor Sensor calibrated for the specific target metallurgy (typically AISI 4140 steel).
• Cable Routing: Avoid routing the coaxial extension cable adjacent to high-voltage power lines to prevent electromagnetic noise induction. Use dedicated protective conduit.
• Torque Limits: Adhere strictly to nominal torque specifications for 3/8-24 UNF threads to prevent deformation of the stainless steel casing.
• Sealing Inspection: Check that the Viton O-ring is free of debris and properly seated before threading the probe into the machine housing to maintain pressure barrier integrity.
