Bently Nevada 330101-00-52-10-02-CN 3300 XL 8 mm Proximity Probe

Description

Engineered for high-reliability vibration and shaft position monitoring, the Bently Nevada 330101-00-52-10-02-CN serves as an industrial-grade non-contacting displacement sensor within the 3300 XL 8 mm Proximity Transducer System. This probe delivers continuous, accurate measurements of shaft displacement, radial vibration, and axial thrust position in critical rotating machinery, offering exceptional resistance to fluid ingress and mechanical wear.

Key Features

• API 670 Compliance: Fully meets industry standards for machinery protection and diagnostic systems.
• ClickLoc Connector: Features a moisture-resistant, gold-plated miniature coaxial ClickLoc connector for secure mechanical coupling.
• Corrosion-Resistant Housing: Standard stainless steel probe case protects inner core assemblies from harsh environments.
• Optimized Thermal Stability: Maintained signal integrity across wide temperature variations typical of heavy industrial turbine halls.

Applications

• Steam and gas turbine shaft vibration analysis.
• Thrust and radial position measurements in centrifugal compressors.
• Hydro-turbine generator shaft monitoring.
• Industrial gearbox and high-pressure pump shaft displacement sensing.

Alternative Models & Compatibility

This 1.0-meter probe requires strict pairing with compatible Bently Nevada components. To form a functional 5.0-meter system, it must be paired with a 4.0-meter extension cable and a 5.0-meter Proximitor Sensor. For a 9.0-meter system, utilize an 8.0-meter extension cable paired with a 9.0-meter Proximitor. Mixing system lengths (e.g., using a 9.0-meter extension cable with a 5.0-meter Proximitor) will cause severe calibration offsets and inaccurate displacement data.

Application Pitfalls & Engineering Notes

The 5.2-inch overall case length is designed for deep-well installations. When mounting this unit, calculate the casing thermal expansion under operational load. Inadequate bracket rigidity or failure to account for casing thermal growth can cause physical contact between the 8 mm tip and the rotating shaft target, leading to immediate sensor failure. Ensure signal cables are routed through dedicated grounded conduits separate from high-voltage AC lines to prevent EMI noise injection.

Commissioning & Calibration Tips

During commissioning, calibrate physical probe gapping using a digital multimeter measuring the DC voltage output at the Proximitor Sensor terminal. A physical gap of 1.0 mm (40 mils) corresponds to a standard sensor bias voltage of -10.0 VDC when calibrated against AISI 4140 steel. Before locking the mounting thread, verify that physical runout and electrical runout do not exceed API 670 guidelines (typically 0.25 mils / 6.3 micrometers combined).
