Bently Nevada 330190-045-00-00 | 3300 XL Extended Temperature Range (ETR) Extension Cable

Product Overview

Bently Nevada 330190-045-00-00 is a 3300 XL Extended Temperature Range (ETR) extension cable designed for vibration monitoring systems operating in thermally demanding industrial environments. It is commonly used in turbines, compressors, and process machinery where stable signal transmission must be maintained under elevated temperature conditions.

This cable supports reliable data transfer between proximity probes and monitoring modules while minimizing signal drift caused by thermal stress. It is applied in power generation, oil and gas, and heavy industrial systems where temperature stability directly affects machine protection accuracy.

The 4.5 meter configuration provides flexible routing in compact and mid-range machinery installations.

Each parameter defines cable length and configuration level within the ETR extension cable family.

Technical Specifications

Engineering Interpretation Notes

The ETR cable design maintains stable electrical characteristics under elevated temperature conditions where standard extension cables may experience signal drift or insulation degradation.

Triaxial construction ensures low-noise signal transmission and stable impedance performance, which is critical for accurate vibration monitoring in rotating machinery.

The cable is optimized for integration in high-temperature zones such as turbine casings and compressor housings.
