The Bently Nevada 330930-065-01-05 is a high-durability extension cable designed for the 3300 NSv (Near Side proximity) Transducer System. This system is specifically engineered for use in tight spaces or with small-diameter shafts where standard 5mm or 8mm probes cannot be utilized. The Bently Nevada 330930-065-01-05 includes stainless steel armor for superior mechanical protection, ensuring that the high-frequency vibration signals remain stable even in environments with physical debris or high-pressure fluids.

Application Fields
The 330930 series is primarily used for monitoring vibration and position on centrifugal compressors, small pumps, and aircraft-derivative gas turbines. Because the NSv system is designed for a smaller “linear range” compared to standard probes, this cable is essential in applications where the probe tip must be placed very close to a small-diameter target. It is frequently found in industrial machinery with limited mounting space or on shafts with high curvature where traditional eddy current sensors would suffer from “side-viewing” interference.
Product Instructions
When installing the armored cable, ensure that the stainless steel jacketing is grounded only at the Proximitor end to prevent ground loops. Although the armor provides excellent protection against crushing and abrasion, avoid exceeding the minimum bend radius of 38 mm (1.5 inches). When connecting the cable to the probe and the Proximitor, verify that the gold-plated pins are free of oil and moisture. It is best practice to use a connector silicone sleeve over the junction to prevent the ingress of industrial contaminants. Secure the armored cable every 0.5 to 1 meter using cable clamps to prevent vibration-induced fatigue.
Common Questions and Answers
Q: Can I use this NSv cable with a standard 3300 XL 8mm probe? A: No. The NSv (Near Side proximity) system has different electrical characteristics and a different operating frequency compared to the 3300 XL series. Interchanging them will result in a failure to calibrate and incorrect readings.
Q: What is the purpose of the stainless steel armor? A: The “01” armor option provides a flexible protective layer that prevents the internal coaxial cable from being cut, pinched, or abraded by moving parts or sharp edges within the machine housing.
Q: How does the cable length affect the vibration reading? A: The total electrical length (cable + probe) must match the calibration of the Proximitor sensor. In this case, the cable is part of a 5.0-meter system. If the total length is incorrect, the “scale factor” (mV/mil) will be wrong, leading to inaccurate data in your monitoring system.
