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

Product Overview

330190-080-00-00 is a Bently Nevada 3300 XL Extended Temperature Range (ETR) extension cable engineered for vibration monitoring systems in turbines, compressors, and critical rotating machinery. It supports stable signal transmission between proximity probes and Proximitor sensors in high-temperature industrial environments such as power plants, oil refineries, and mining operations.

The 3300 XL ETR cable maintains measurement integrity under thermal stress and continuous vibration exposure. It uses a 75 ohm triaxial structure with FEP insulation to improve dielectric stability and chemical resistance. This design reduces signal drift and helps condition monitoring systems maintain accurate shaft displacement and vibration data.

Operators use this cable in environments where standard extension cables fail due to elevated temperature or chemical exposure. It directly supports machine protection strategies by reducing false alarms and preventing unnecessary shutdown events in critical production assets.

Suffix Breakdown and Configuration Logic

The ETR design focuses on thermal resilience rather than certification variants. The structure uses triaxial geometry with FEP insulation to maintain electrical stability in elevated temperature zones.

Technical Specifications

Technical FAQs

Is 330190-080-00-00 compatible with standard 3300 XL probes?
Yes. It works with Bently Nevada 3300 XL proximity transducer systems when used with compatible probes and Proximitor sensors.

What is the main advantage of ETR cable over standard extension cable?
ETR cable provides higher temperature tolerance and improved insulation stability in harsh environments.

Can this cable operate in turbine casing environments?
Yes. It is commonly installed in turbine housings where heat and vibration exceed standard cable limits.

Does cable length affect calibration?
Yes. System loop calibration must match total probe, extension, and Proximitor configuration.

Engineering & Installation Notes

Maintain proper separation between signal cables and power wiring to reduce electromagnetic interference in high-noise environments such as VFD-driven compressor systems.

Do not exceed minimum bend radius during installation. Mechanical stress on triaxial shielding can degrade signal stability over time.

In high-temperature zones, route cables away from direct radiant heat sources. Use approved clamps to prevent vibration fatigue at connector points.
