Bently Nevada 330171-00-32-05-01-CN 3300 5 mm Proximity Probe

Description

Engineered for high-precision dynamic displacement and vibration measurements within demanding industrial machinery environments, the Bently Nevada 330171-00-32-05-01-CN serves as a critical non-contact transducer element in industrial asset protection systems. This 5 mm proximity probe is optimized for tight mechanical installations where physical clearances restrict the use of standard 8 mm probes, while maintaining the high sensitivity required for fluid-film bearing monitoring. Constructed with a 0.5-meter standard cable and terminating in a miniature coaxial ClickLoc connector with integrated protection, it ensures robust signal integrity and resistance to harsh lubricating oils and moisture.

Key Features

• Optimized 5 mm Tip Diameter: Ideal for compact spatial arrangements and narrow installation areas.
• ClickLoc Miniature Coaxial Connector: Features a secure connection mechanism equipped with a connector protector to prevent fluid ingress and mechanical decoupling.
• Rugged Cable Construction: Fitted with a standard, oil-resistant coaxial cable designed to withstand persistent industrial environments.
• High-Fidelity Signal Integrity: Delivers precise eddy-current measurement profiles with minimal signal drift over prolonged runtime.
• Specific Agency Approval: Designated with the "CN" country-specific approval option for direct deployment in restricted regulatory regions.

Applications

• Radial shaft vibration measurements on high-speed turbomachinery.
• Axial thrust position monitoring in centrifugal compressors and pumps.
• Dynamic shaft motion analysis in steam and gas turbine systems.
• Eccentricity measurements on machine tool spindles and auxiliary power units.

Alternative Models & Compatibility

This 5 mm probe must be paired exclusively with a matching 5 mm Proximitor Sensor. Mixing a 5 mm probe with a standard 3300 XL 8 mm Proximitor Sensor will alter the nominal system scale factor (typically 7.87 V/mm or 200 mV/mil), leading to severe calibration errors and incorrect machinery protection system action. Verify that the system length calibration (0.5-meter probe + extension cable length) matches the configuration of your Proximitor Sensor (e.g., 5-meter or 9-meter total system length).

Application Pitfalls & Engineering Notes

During mounting in tight bearing housings, ensure that no cross-threading occurs on the 3.2-inch case. Because this unit has an unthreaded length of 0.0 inches, threading begins immediately at the head. A lack of proper thread alignment can damage housing tap threads. Furthermore, maintain the minimum specified bend radius of 25.4 mm (1.0 inch) for the coaxial cable during routing to avoid micro-fracturing the internal signal lines.

Commissioning & Wiring Tips

When joining the miniature coaxial connection to the extension cable, perform a strict electrical isolation check before locking the ClickLoc protector. The resistance between the center conductor and outer shell, with the probe isolated from the target, should read as an open circuit. Verify that the physical connection is completely dry; trace moisture inside the ClickLoc shell introduces a parallel resistance path, mimicking target distance changes and triggering false DC voltage offset faults in the monitor.
