Quick Detail

Description

The Bently Nevada 330930-045-04-05 is a high-performance 3300 NSv Extension Cable, engineered to serve as the critical link within precision machinery condition monitoring systems. Specifically designed to extend the reach between proximity probes and their associated monitors or Proximitor transducers, this extension cable maintains signal integrity over extended distances, ensuring that vital data on shaft vibration, position, and speed is transmitted without degradation. With a dedicated cable length of 4.5 meters (14.8 feet), this model provides the necessary reach for installations where sensors are located a considerable distance from the system's processing unit, offering flexibility in complex industrial layouts found in power generation, petrochemical, and heavy manufacturing plants.

Constructed for maximum durability and reliability in demanding environments, the 330930-045-04-05 features a robust stainless steel armor as part of its protective design. This flexible AISI 302 SST armor provides exceptional mechanical protection against crushing, abrasion, and incidental impact, safeguarding the delicate internal conductors during installation and throughout its operational life in high-vibration areas. The cable core itself is a precision 70 Ω coaxial type, insulated with fluoroethylene propylene (FEP), a material renowned for its excellent chemical resistance, thermal stability, and low dielectric loss. This construction ensures stable electrical performance across the specified operating and storage temperature range of -55°C to +170°C (-67°F to +338°F), making it suitable for use in both extreme heat and cold.

The cable is terminated with secure connectors and includes a connector protector, preventing damage to the electrical contacts during handling and installation. Its design incorporates a low and consistent extension cable capacitance (69.9 pF/m typical), which is crucial for preserving the linearity and accuracy of the eddy current measurement signal over the entire 4.5-meter length. Furthermore, the 330930-045-04-05 carries multiple agency approvals, facilitating its deployment in projects requiring compliance with international safety and performance standards.

Applications

1. Extending Sensor Reach in Large Machinery Trains

This 4.5-meter extension cable is essential for connecting proximity probes mounted on large equipment, such as turbines or multi-stage compressors, to remotely located junction boxes or monitoring panels. Its length bridges significant gaps, allowing for optimal sensor placement without compromising signal quality, and often eliminates the need for multiple splices, thereby enhancing overall system reliability.

2. Durable Signal Transmission in Physically Demanding Environments

The inclusion of stainless steel armor makes this cable ideal for installations where the cable run is exposed to severe physical hazards. This includes routing through areas with high risk of abrasion from moving parts, being stepped on, or crushed by other equipment. It is perfectly suited for harsh environments in steel mills, mining, or pulp and paper plants, where cable integrity is paramount to avoid costly signal loss or system downtime.

3. System Retrofit and Expansion with Guaranteed Performance

For upgrading legacy monitoring systems or adding new measurement points to an existing 3300 NSv network, this pre-configured extension cable offers a guaranteed-compatibility solution. Its standardized 70 Ω impedance and FEP insulation ensure it meets the exact electrical requirements of the system, simplifying engineering efforts and ensuring the new or upgraded loop performs as intended without requiring extensive recalibration or testing.

Specifications

Competitive Advantage

1. Military-Grade Physical Protection with Stainless Steel Armor

The standout feature is its integrated flexible AISI 302 stainless steel armor. This provides superior protection against crushing, cut-through, and severe abrasion compared to standard plastic-jacketed cables. This dramatically extends service life in punishing environments, reduces maintenance interventions due to cable damage, and lowers the total cost of ownership by virtually eliminating this common point of failure.

2. Precision Engineered for Uncompromised Signal Integrity

Beyond physical toughness, the cable is precision-engineered for electrical excellence. Its 70 Ω coaxial design with FEP insulation ensures a stable characteristic impedance and a very low, consistent capacitance per meter. This specialized construction is critical for accurately transmitting the high-frequency signals from eddy current probes over the full 4.5-meter length without introducing signal distortion, attenuation, or phase shift, which is vital for precise vibration and position measurement.

3. Simplified Global Compliance and Hassle-Free Deployment

Holding multiple agency approvals, this cable is pre-certified for use in a wide range of industrial applications and geographic regions. This removes a significant administrative and technical hurdle for project engineers, speeding up deployment, ensuring regulatory compliance, and providing peace of mind that the component meets stringent international safety and performance standards right out of the box.

4. Optimized Length and Durability for Real-World Installations

The 4.5-meter length is a practical offering that covers a vast majority of common installation runs without excessive waste. Combined with its armored durability, this specific length provides an optimal balance between installation flexibility, material cost, and long-term reliability. It allows installers to complete runs cleanly while providing the robust protection needed where cables are most vulnerable, delivering exceptional value and reliability.
