Product Overview

The Bently Nevada 330130-080-01-05 is a high-integrity armored extension cable designed for the 3300 XL 8mm Proximity Transducer System. This critical interconnect component bridges the distance between a proximity probe and a Proximitor sensor, ensuring the precise transmission of eddy current signals without data degradation. Measuring 8.0 meters in length, this cable is engineered to maintain the system's electrical calibration and impedance standards. It serves as a vital link in Turbine Supervisory Instrumentation (TSI) setups, where maintaining signal fidelity over a specific distance is mandatory for the accurate measurement of vibration and shaft position in high-value rotating machinery.

• Standards Compliance: Fully compliant with API 670 requirements for vibration monitoring system components

Engineering Utility and Operational Context

This 8.0-meter armored cable is indispensable for large-scale industrial installations where the monitoring rack or junction box is situated at a significant distance from the machine casing. It is primarily deployed on large steam turbines, high-capacity centrifugal compressors, and industrial generators to monitor radial shaft vibration and axial thrust position. The armored exterior is particularly beneficial in power generation and petrochemical facilities where cables are exposed to mechanical hazards, hot lubricating oils, or high-pressure washdowns. By maintaining the integrity of the 100 mV/mil (3.94 V/mm) scale factor, the 330130-080-01-05 enables 3500 series monitoring systems to provide the reliable diagnostic data needed for automated machinery protection and proactive maintenance planning.
