Bently Nevada 330190-080-00-CN | 3300 XL Extended Temperature Range (ETR) Extension Cable

Product Overview

Bently Nevada 330190-080-00-CN is a 3300 XL Extended Temperature Range (ETR) extension cable designed for vibration monitoring systems operating in elevated and thermally unstable industrial environments. It is applied in turbines, compressors, petrochemical units, and power generation systems where signal stability must be maintained under continuous thermal stress.

This cable supports reliable signal transmission between proximity probes and monitoring modules while maintaining electrical integrity across extended temperature conditions. It reduces measurement drift and protects machine protection systems from signal degradation in harsh operating zones.

The 8.0 meter configuration provides flexible installation for distributed monitoring layouts in large industrial machinery assemblies.

Technical Configuration Breakdown

This structure defines mechanical configuration, electrical design standard, and compliance classification within the ETR extension cable family.

Technical Specifications

Engineering Interpretation Notes

The ETR cable series is designed for environments where standard extension cables cannot maintain stable electrical characteristics under elevated temperatures.

Fluoroethylene propylene (FEP) insulation improves thermal resistance and chemical stability, making the cable suitable for oil, gas, and high-temperature industrial environments.

Triaxial construction ensures low-noise signal transmission and stable impedance characteristics across long cable runs.

Field Application Notes

Where is this cable used?
It is used in turbines, compressors, and high-temperature industrial monitoring systems.

What makes ETR cables different?
They maintain electrical stability under extended temperature conditions.

Is it compatible with standard 3300 XL systems?
Yes. It is fully compatible with 3300 XL proximity measurement architecture.

Why is triaxial construction important?
It reduces noise and improves signal stability in electrically harsh environments.

Installation & Commissioning Notes

Avoid routing near high-temperature steam lines or heat sources exceeding rated limits.

Ensure proper grounding of shielding to maintain signal integrity in noisy electrical environments.

Maintain proper bend radius to avoid degradation of triaxial shielding structure.

Verify connector seating before commissioning to ensure stable measurement output.

Engineering & Operational Guidance

Use thermal spacing in cable routing to avoid continuous exposure to radiant heat sources.

Ensure proper strain relief at cabinet entry points to prevent mechanical stress transfer.

Inspect insulation condition periodically in high-temperature applications.

Maintain separation from high-power electrical cables to minimize EMI interference.
