330130-085-00-CN Bently Nevada 8.5m Standard Extension Cable

Product Overview

The Bently Nevada 330130-085-00-CN is an 8.5-meter standard extension cable, a fundamental component of the industry-leading 3300 XL 8mm Proximity Transducer System. Designed to bridge the gap between a proximity probe and a Proximitor® Sensor, this cable ensures the integrity of eddy current measurements across a 2 mm (80 mils) linear range. Manufactured in the U.S.A., the 330130-085-00-CN is optimized for performance in temperatures between +18°C and +27°C and features the CN agency approval for specific regional regulatory compliance. Its lightweight yet robust design makes it the standard choice for reliable machinery health monitoring.

Core Technical Advantages

Standard XL Connectivity

The 330130-085-00-CN utilizes a standard cable design that balances flexibility with electrical precision. With a typical capacitance of 69.9 pF/m, it maintains the strict signal characteristics required for the 3300 XL system to achieve high-accuracy interchangeability between probes and sensors without custom calibration.

Patented CableLoc™ Technology

Durability is built into the cable’s DNA. The patented CableLoc design provides a robust 330 N (75 lbf) pull strength, ensuring the connection remains secure during installation or in high-vibration environments. This provides a more secure attachment than previous designs, reducing the risk of signal loss due to mechanical stress.

Exceptional Electrical Stability

This extension cable is specified for a core DC resistance of 1.87 ± 0.28 Ω and a jacket resistance of 0.56 ± 0.11 Ω over its 8.5-meter length. These tight tolerances ensure that the transducer system remains accurate even when exposed to 93% humidity, with less than a 3% change in Average Scale Factor (ASF).

Technical Specifications

Installation & Operation Notes

• Total System Length: It is mandatory that the extension cable length (8.5m) and probe length (e.g., 0.5m) add up to the calibrated total length of the Proximitor Sensor (9.0m).
• Connector Protection: Each cable includes silicone tape. However, if the connection will be exposed to turbine oil, a factory connector protector option should be used instead of tape.
• Environmental Limits: While rated for 93% humidity, the system performance is specified for altitudes up to 2000 meters. For higher altitudes or extreme chemical exposure, contact technical support.

Technical FAQs

Q1: Can I use this cable with a 3300 XL 5 meter system?

A1: No. This 8.5m cable is specifically intended for a 9-meter total system. Using it with a 5m Proximitor sensor will cause incorrect data output and calibration errors.

Q2: What does the "CN" approval signify?

A2: The CN suffix indicates that the cable meets specific regional regulatory or agency requirements for the destination country, ensuring compliance with local industrial standards.

Q3: Is this cable resistant to turbine oil?

A3: While the cable itself is durable, the standard connection (sealed with silicone tape) is NOT recommended for direct turbine oil exposure. For such environments, the FluidLoc option is preferred.
