The Bently Nevada 330171-00-12-10-01-05 is a high-performance extension cable designed for the 3300 XL 5mm Proximity Transducer System. This cable acts as the vital bridge between the proximity probe and the Proximitor sensor, transmitting high-frequency signals with minimal loss or interference. Engineered for industrial environments, the Bently Nevada 330171-00-12-10-01-05 features a specialized coaxial design that ensures constant impedance, which is critical for maintaining the accuracy of vibration and position measurements in rotating machinery.

Application Fields
This extension cable is primarily used in vibration monitoring systems for medium-sized rotating equipment where space is constrained, requiring the 5mm probe diameter. Common applications include monitoring small steam turbines, centrifugal pumps, and electric motors. It is specifically designed to function within the Bently Nevada 3500 and 2300 monitoring racks, providing the high-fidelity signal transmission necessary for detecting shaft radial vibration, axial thrust, and phase reference (Keyphasor) data.
Product Instructions
When installing the cable, avoid sharp bends; the minimum bend radius should be maintained at 25.4 mm (1 inch) to prevent damage to the internal coaxial structure. Ensure that the connectors are completely clean and dry before mating. Hand-tighten the connectors firmly; do not use pliers, as over-tightening can deform the gold-plated contacts. For applications involving exposure to fluids, it is highly recommended to use heat-shrink tubing or connector protectors to prevent moisture ingress. The cable must be secured with clips or conduit to prevent whipping or mechanical fatigue caused by machine vibration.
Common Questions and Answers
Q: Can I cut this cable to a shorter length if it is too long? A: No. The length of the extension cable is a critical part of the circuit’s total capacitance. Cutting the cable will change the electrical properties and cause the Proximitor to give incorrect vibration readings.
Q: What is the difference between the 5mm and 8mm extension cables? A: While they look similar, they are electrically tuned to their respective probe diameters. The 330171 is specifically calibrated for use with 3300 XL 5mm probes and cannot be interchanged with 8mm systems without causing significant calibration errors.
Q: Does this specific model come with protective armor? A: Based on the “00” configuration in the part number, this specific unit is the standard unarmored version. If your environment involves high physical risk or abrasive contact, an armored version (usually designated with “01” or “02”) should be used.
