Bently Nevada 330101-00-33-05-02-00 3300 XL 8 mm Proximity Probe

Description

Engineered for highly precise machinery condition monitoring, the Bently Nevada 330101-00-33-05-02-00 is an unarmored 8 mm proximity probe configured with a fully threaded 3.3-inch case (0.0-inch unthreaded length) and a short 0.5-meter (1.6-foot) standard coaxial cable terminated with a miniature ClickLoc connector. Unlike armored options or variants with integrated connector protectors, this specific configuration features a streamlined, non-armored design and standard cable optimized for compact bearing housings or tight mounting installations where physical space is at a premium and a separate extension cable completes the monitoring loop. Operating on the eddy current principle, this high-performance sensor provides stable, non-contact static and dynamic displacement measurements, making it ideal for tracking shaft vibration, radial position, and axial thrust in critical industrial rotating machinery.

Features

• Fully Threaded Case: A 3.3-inch (84 mm) case length with 0.0 inches of unthreaded body allows maximum threading engagement into brackets or machine casings.
• Standard Non-Armored Cable: Streamlined, lightweight standard 75-ohm coaxial cable provides flexibility in standard cable routing ducts.
• Miniature ClickLoc Coaxial Connector: Quick-connect style gold-plated coaxial connector facilitates secure, low-loss coupling to the extension cable.
• 0.5-Meter Length: Extremely compact lead length prevents excess cable slack in closely coupled installations.
• Eddy Current Measurement Principle: Achieves highly accurate, non-contact shaft position and vibration displacement readings.

Applications

The 330101-00-33-05-02-00 proximity probe is typically deployed within a 3300 XL 8 mm transducer system in heavy-industry rotating machinery. Recommended applications include:

• Steam and Gas Turbines: High-speed shaft vibration, axial thrust, and radial displacement monitoring.
• Centrifugal Compressors and Pumps: Rotor dynamic tracking and bearing clearance measurements.
• Gearboxes and Fans: Industrial fan shaft tilt and gear shaft radial vibration.
• Close-Coupled Bearings: Bearing housings with limited internal clearance where a 0.5-meter sensor lead is ideal.

Installation Guidelines

To ensure optimal measurement accuracy and system reliability, adhere to the following installation practices:

• Probe Gapping: Set the initial probe gap (typically 1.27 mm or 50 mils) to establish the midpoint of the linear range using a digital voltmeter measuring the Proximitor output voltage.
• Target Area: Ensure the target is a minimum diameter of 15.2 mm (0.6 in) and made of standard AISI 4140 steel for optimal calibration alignment.
• Thread Torque: Do not exceed recommended thread installation torque. Hand-tighten and secure with locking nuts in bearing housings.
• Cable Routing: Avoid sharp bends; maintain standard coaxial minimum bend radii. Ensure clean, finger-tight connections on the ClickLoc connector.
