Bently Nevada 330130-080-01-05 Armoured Extension Cable

The Bently Nevada 330130-080-01-05 is an armoured extension cable from the 3300 XL series. It links proximity probes to drivers while protecting the signal path mechanically. Industrial plants deploy it on turbines, compressors, and large rotating machines. Consequently, it suits installations where abrasion and mechanical stress threaten standard cables.

Construction and Component Count

Each assembly includes two coaxial connectors plus a full-length armoured jacket. The 330130-080-01-05 combines triple shielding with a stainless steel protective layer. Furthermore, the FEP inner jacket resists oil, moisture, and chemical attack. Stainless steel connectors endure repeated mating cycles during maintenance activities.

Signal Path and Energy Storage

This cable carries no active electronics or internal energy storage components. Instead, it passively transfers high-frequency signals between the probe and driver. The stable 75 Ω impedance prevents reflections and excessive signal loss. As a result, measurement accuracy remains consistent along the entire cable run.

Installation and Routing Guidance

Technicians must respect the 38 mm minimum bend radius during installation. Additionally, route the cable away from high-voltage conductors and variable-frequency drives. The armoured layer protects against impact, vibration, and mechanical abrasion. Always confirm total system length against the driver specifications.
