Bently Nevada 330171-00-16-10-02-00 3300 5mm Proximity Probe

Product Overview

The Bently Nevada 330171-00-16-10-02-00 is a high-precision 3300 5mm Proximity Probe designed for non-contacting measurements in confined industrial spaces. As a critical sensor in the 3300 XL ecosystem, this 5mm probe offers the same 2.0 mm (80 mil) linear range as the standard 8mm probe but with a smaller physical footprint. It is specifically engineered to measure radial vibration and axial position on smaller rotating assets or in machinery where mounting space for a standard 8mm probe is unavailable.

Functional Engineering & Stability

The 330171 series is renowned for its temperature stability. Across its full operating range of -35°C to +177°C, the incremental scale factor remains within $\pm$ 10% of the standard 7.87 V/mm (200 mV/mil). This accuracy ensures that vibration data remains reliable even during significant thermal cycles of the machinery. The probe utilizes a specialized 1/4-28 UNF thread and is supplied without armor for maximum flexibility in tight routing applications.

Technical Specifications

Technical FAQs

What are the mounting limitations for the 5mm probe?Due to the smaller diameter, the 1/4-28 UNF casing has a maximum thread engagement limit of 0.375 in. Over-tightening or exceeding this engagement depth can potentially stress the probe case or interfere with the internal coil alignment.

Is the ClickLoc™ connector compatible with standard cables?Yes. The 02 connector option features the ClickLoc™ miniature coaxial design. It is gold-plated and specifically engineered to resist loosening under high-vibration conditions, providing a robust "click-to-lock" connection with 3300 XL extension cables.

Does this probe require a specific Proximitor®?While 5mm probes share the same scale factor as 8mm probes, they must be used with a 3300 XL Proximitor Sensor calibrated for the specific total system length (in this case, 1.0m probe + extension cable = 5m or 9m total system).

Field Engineering & Installation Guide

• Gap Setting: Use a high-quality multimeter to set the "Static Gap." For a standard -24V supply system, the probe is typically positioned so the Proximitor output is at -10.0 VDC (the midpoint of the 80-mil linear range).

• Target Material: Standard probes are calibrated for AISI 4140 steel. If your shaft is made of a different alloy, the voltage-to-distance relationship will shift, requiring a scale factor adjustment in your monitoring software.

• Cable Management: Since this version is without armor, ensure the coaxial cable is routed through a protective conduit or secured with clips away from sharp edges and high-voltage motor leads to prevent signal interference (EMI).

Engineering Advantages

The Bently Nevada 330171-00-16-10-02-00 allows for high-fidelity vibration monitoring in small-bore bearing housings and high-density machinery. Its precision-molded tip is resistant to the harsh oils and chemical environments found in turbines and compressors. For B2B procurement, sourcing an original Made in U.S.A. probe ensures adherence to API 670 standards, providing the 12-month warranty and long-term reliability required for critical asset protection.
