Product Description
The 330850-90-05 is a component of the Bently Nevada 3300 XL Proximity Transducer System, specifically identified as an Extension Cable Assembly. This model is designed to provide a reliable electrical connection between a proximity probe (likely an 8mm or 5mm model) and the system's proximitor (preamplifier). The "-90-" in the part number typically denotes a specific cable length, and the "-05" suffix indicates it is terminated with a "California Style" connector, which plugs directly into a compatible slot in the monitoring rack. Its primary function is to transmit high-frequency eddy current signals with minimal loss and interference, ensuring the accuracy of vibration and position measurements for machinery protection.

Application Scenarios
This extension cable is a fundamental component in machinery condition monitoring systems, used to bridge the distance between the sensor and the monitoring rack in a wide range of industrial applications.
Power Generation: Connecting proximity probes on steam turbines and gas turbines to the centralized monitoring system, ensuring a clean signal path for vital vibration and Keyphasor® data.
Oil & Gas: Essential for wiring vibration probes on critical equipment like compressors and pumps back to the control system rack, helping to maintain compliance with API 670 standards.
Hydroelectric Power Plants: Extending the reach of probes monitoring generator shafts in large power units.
General Heavy Industry: Used in any facility with a 3300/3500 monitoring system to connect proximity probes on motors, fans, and gearboxes directly to the rack.
