330171-00-26-10-02-00 Bently Nevada 3300 5mm Probe | 1m

Product Overview: 330171-00-26-10-02-00

From a maintenance engineer's perspective, the Bently Nevada 330171-00-26-10-02-00 is a 5 mm eddy current proximity probe engineered for precise, long-term shaft displacement measurement. As part of the 3300 series, this probe provides the exact electrical characteristics required for reliable machinery protection. The 330171-00-26-10-02-00 features a 1/4-28 UNF thread, a 1.0 metre total length, and a miniature coaxial ClickLoc connector, making it a direct-fit solution for standard mounting configurations. Its unarmored design allows for flexible routing in tight spaces, while the AISI 304 stainless steel case ensures durability in harsh industrial environments.

Key Specifications and Performance

The 330171-00-26-10-02-00 operates with a -17.5 Vdc to -26 Vdc power supply and draws a maximum of 12 mA. For accurate linear range, operation at a more positive voltage than -23.5 Vdc is not recommended. The probe's output resistance is 50 Ω, and its DC resistance from center conductor to outer conductor is 7.59 ± 0.50 Ω. The polyphenylene sulfide (PPS) probe tip offers excellent chemical and thermal stability, with a probe temperature range of -35°C to +177°C. The 75 Ω triaxial FEP-insulated cable ensures signal integrity, and the probe's tensile strength of 222 N provides robust pull resistance.

Installation and Maintenance Guidance

When installing the 330171-00-26-10-02-00, use a #3 or larger tap drill for the 1/4-28 mounting hole. The maximum thread engagement is 0.375 in, and the recommended probe case torque is 5.1 N·m (45 in·lb), with a maximum of 7.3 N·m (65 in·lb). The minimum cable bend radius is 25.4 mm (1.0 in) to prevent damage. For reliable operation, avoid exposing the probe to temperatures below -34°C, as this may cause premature pressure seal failure. Periodic inspection of the probe tip and cable is advised to detect wear or contamination.

Applications and Compatibility

The 330171-00-26-10-02-00 is suitable for use with Bently Nevada 3300 series monitoring systems. Its 5 mm probe tip and 1/4-28 thread make it ideal for measuring radial vibration, axial position, and eccentricity on steam turbines, compressors, and pumps. The miniature coaxial ClickLoc connector ensures a secure, repeatable connection. For integration with other systems, verify compatibility with your specific monitor and extension cable.
