Description

Bently Nevada 330130-085-01-00 3300 XL Standard Extension Cable

The Bently Nevada 330130-085-01-00 is a high-integrity extension cable designed for the 3300 XL 8 mm Proximity Transducer System. It serves as the primary electrical interface between an eddy current proximity probe and a Proximitor sensor. By facilitating high-frequency signal transmission with minimal impedance variation, this cable ensures that critical machinery protection systems receive precise displacement data for monitoring shaft vibration, axial position, and speed in rotating equipment.

Advanced Shielding and Environmental Resilience

The construction of the 330130-085-01-00 is optimized for the rigorous conditions found in power plants, refineries, and manufacturing facilities. Specifically, it utilizes a fluoro-polymer (FEP) insulated coaxial design that provides exceptional shielding against electromagnetic interference (EMI). Furthermore, this material choice ensures the cable remains resilient when exposed to corrosive industrial lubricants, moisture, and high-pressure steam. As a result, the transducer system maintains its calibrated linear scale factor of 7.87 V/mm (200 mV/mil) over long-term deployments, reducing the risk of signal drift or false machinery alarms.

Technical Specification Matrix

Machinery Protection and Global Compliance

For facilities utilizing Turbine Supervisory Instrumentation (TSI), the 330130-085-01-00 is a critical asset. Moreover, the -01 option provides a factory-installed connector protector, which shields the coaxial junction from oil ingress and contamination—a common requirement for cables routed inside bearing housings. In addition, the 8.5-meter length is specifically calibrated to meet the electrical requirements of a 9.0-meter total system length when paired with a 0.5-meter probe. Therefore, this cable is a globally recognized solution for ensuring the safety and reliability of high-speed compressors, turbines, and large-scale industrial motors.

FAQ

What is the purpose of the connector protector on this model?

The -01 option indicates the presence of a connector protector sleeve. Specifically, this sleeve prevents the connection between the probe and the extension cable from becoming contaminated by oil, water, or debris. Accordingly, this is highly recommended for any installation where the junction is not housed within a dry, clean conduit.

How does total system length affect the 330130-085-01-00?

Proximity transducer systems are calibrated based on total electrical length. Furthermore, this 8.5-meter cable must be matched with the correct probe and Proximitor sensor (typically a 9.0-meter system) to maintain the specified linear range. Consequently, using an incorrect cable length will result in an inaccurate scale factor and unreliable vibration readings.

Can this cable be used in explosive environments?

Yes, when installed as part of a certified Bently Nevada system with the appropriate safety barriers, this cable meets international standards for hazardous areas. As a result, it is suitable for use in Class I, Division 1 and Zone 0/1 environments where flammable gases or vapors may be present.

What are the benefits of the gold-plated ClickLoc connectors?

The ClickLoc connectors feature a mechanical locking mechanism and gold-plated surfaces. Ultimately, this design ensures a low-resistance electrical path that will not vibrate loose, preventing the “signal spikes” that often lead to unnecessary machinery trips in critical protection loops.
