Quick Detail

Description

The 330930-040-00-05 represents a high-integrity signal transmission solution within the renowned 3300 NSv Extension Cable series. Specifically engineered for the Bently Nevada 3300 NSv proximity transducer system, this extension cable acts as the vital electrical bridge between the proximity probe and the Proximitor sensor. In critical machinery monitoring, the precision of data transmission is paramount; the 330930-040-00-05 is designed to maintain the highest levels of signal fidelity, ensuring that minute shaft vibrations and axial displacements are accurately reported to the plant's protection system without interference or loss.

Measuring 4.0 meters (13.1 feet) in length, this 3300 NSv Extension Cable offers the necessary reach for complex industrial installations where monitoring points are distanced from electronics enclosures. The 330930-040-00-05 is distinguished by its robust "00" and "05" options, which specify the inclusion of stainless steel armor and an FEP (Fluorinated Ethylene Propylene) jacket. This armored configuration is essential for protecting the internal coaxial core from physical crushing, abrasive rubbing, and environmental degradation. The FEP jacket provides an additional layer of chemical resistance, making the 3300 NSv Extension Cable impervious to most industrial solvents, oils, and moisture typically found in petrochemical and power generation environments.

Applications

The 330930-040-00-05 is primarily utilized as the intermediate link in the 3300 NSv proximity transducer system, specifically for monitoring small-diameter shafts or targets where high-resolution displacement data is required. By connecting a 3300 NSv probe to a Proximitor sensor, it enables the accurate measurement of radial vibration and axial position in centrifugal compressors, specialized pumps, and small steam turbines. Its 4.0-meter length provides the flexibility needed to route cables from the machine bearing housing to local junction boxes while maintaining calibrated electrical impedance.

In heavy industrial zones where mechanical hazards are prevalent, the 3300 NSv Extension Cable serves as a ruggedized signal path. Its stainless steel armor makes it ideal for installation in areas where maintenance personnel may step on cables or where debris might cause abrasion. It is frequently applied in hydroelectric facilities and cooling tower fans where cables must be routed through exposed conduits or along machinery frames subjected to constant mechanical stress and fluid splashes.

This extension cable is also critical for high-temperature applications and specialized machinery layouts that demand extreme environmental resilience. Capable of operating in temperatures ranging from -50°C to +175°C, the 330930-040-00-05 is deployed in the "hot zones" of industrial machinery, such as near gas turbine casings or high-pressure steam lines. The FEP jacket ensures that even under constant thermal cycling and exposure to synthetic lubricants, the cable’s insulation remains intact, preventing signal drift and ensuring continuous machinery protection.

Specifications

Competitive Advantage

Superior Mechanical Protection with Stainless Steel Armor: Unlike standard non-armored cables, the 330930-040-00-05 features integrated stainless steel armor that provides exceptional resistance to crushing and cutting. This design significantly reduces downtime caused by accidental cable damage during routine machinery maintenance and extends the operational life of the sensor string in abrasive environments.

Advanced Chemical and Thermal Resilience: The use of a high-grade FEP jacket allows this 3300 NSv Extension Cable to function reliably in extreme temperatures up to +175°C. This material choice also provides a nearly inert barrier against corrosive chemicals and hydrocarbons, ensuring that the cable does not become brittle or degrade when exposed to harsh industrial fluids.

Secure ClickLoc and Connector Protection: The cable is equipped with Bently Nevada’s proprietary ClickLoc miniature coaxial connectors. The inclusion of a connector protector (option 05) ensures that the connection point remains free from moisture and contaminants while providing a locking mechanism that resists loosening due to machinery vibration, guaranteeing a "set-and-forget" installation.

Precision-Matched Electrical Performance: The 330930-040-00-05 is manufactured with strictly controlled capacitance and resistance values. This precision ensures seamless integration with 3300 NSv probes, eliminating the need for complex field calibration and ensuring that the transducer system maintains its rated sensitivity and 1.0 mm (40 mils) gap performance.
