330930-040-00-00 Bently Nevada 3300 XL Standard Extension Cable -52°C To +177°C

Product Overview
The Bently Nevada 330930-040-00-00 is a high-performance standard extension cable from GE Bently Nevada's 3300 XL NSv series, designed specifically for industrial rotating machinery condition monitoring systems. This cable connects 3300 NSv proximity probes and proximitor sensors to create complete 5-meter or 7-meter system lengths, enabling precise signal transmission of key parameters such as vibration and displacement.

As a core component of Bently's vibration monitoring systems, the 330930-040-00-00 features a 75Ω coaxial cable construction with FEP fluoroplastic insulation, ensuring stable and reliable signal transmission in harsh industrial environments. It is particularly suitable for equipment with stringent installation requirements, such as centrifugal compressors, refrigeration compressors, and process gas compressors.

Key Features and Benefits

Superior Environmental Adaptability

- **Extremely Wide Operating Temperature**: -52°C to +177°C (-62°F to +351°F), adaptable to extreme high and low temperature environments

- **Excellent Chemical Resistance**: Compared to the traditional 3300 RAM series, NSv cables offer superior chemical resistance, suitable for a variety of process compressor applications

- **Optional Armor Protection**: Available in stainless steel armored versions (e.g., 330930-040-04-00) for enhanced mechanical protection

Reliable Connection Design

- **ClickLoc Connector**: Gold-plated brass connectors with a self-locking function prevent loosening and ensure a secure connection

- **CableLoc Design**: Tensile strength up to 220N (50 psi) at the probe housing to probe leads and probe leads to extension cable connections

- **Signal Integrity**: FEP insulation and 75Ω precision impedance design minimize signal attenuation and electromagnetic interference

System Compatibility

- **Full Interchangeability**: Compatible with Bently Nevada's existing 3300... RAM proximity probes and extension cables are interchangeable.

- **Standard System Length**: 4.0-meter cable length, which can be combined with probes and preamplifiers to build 5-meter or 7-meter standard monitoring systems.

- **3300 XL Series Compatibility**: Perfectly matches Bentley 3300 XL NSv proximity probe systems and 990 vibration transmitters.
