The Bently Nevada 330104-08-12-10-02-00 is a high-performance 3300 XL 8 mm proximity probe designed for eddy current transducer systems. This transducer system provides precise, non-contact measurement of shaft vibration and position in rotating machinery, such as steam turbines, gas turbines, and centrifugal compressors. The 3300 XL series is engineered for high accuracy, temperature stability, and full compatibility with API 670 standards.

Features

• Advanced eddy current proximity sensing technology.
• Complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need for individual component matching or bench calibration.
• Standard 8 mm probe design with M10 x 1 threads.
• Includes armored cable for enhanced mechanical protection in harsh industrial environments.
• Equipped with a miniature coaxial ClickLoc connector.

Applications

• Vibration Monitoring (Dynamic): Detects radial vibration and shaft unbalance to trigger alarms or automatic machine trips, preventing mechanical failure.
• Thrust/Axial Position (Static): Monitors axial shaft movement to detect bearing wear or failure.
• Industrial Sectors: Widely used in power generation (turbines), oil and gas (compressors/pumps), petrochemical (fans/agitators), and heavy industry (blowers/paper mills).

Technical Specifications

Installation Guidelines

• Handling: Proximity probes are sensitive electronic components. Handle with care to avoid damage to the probe tip or connector pins.
• Mounting: Ensure the probe is mounted in a rigid bracket to prevent mechanical resonance. Maintain the specified gap distance from the target shaft as per the system calibration.
• Wiring: Use only compatible Bently Nevada extension cables. Ensure all connections are clean and fully seated (ClickLoc connectors must be locked).
• Grounding: Follow standard industrial grounding practices for instrumentation to minimize EMI/RFI interference.
• Power: Always disconnect power from the Proximitor sensor before connecting or disconnecting the probe to prevent electrical damage.

FAQ

What is the typical gap voltage for this sensor?

When properly installed, the Proximitor sensor output should be approximately -9 VDC to -11 VDC, operating within a linear range of -1 VDC to -17 VDC.

Are 3300 XL components interchangeable with older systems?

Yes, 3300 XL 8 mm components are both electrically and physically backward compatible with non-XL 3300 5 mm and 8 mm transducer system components.
