Bently Nevada 330130-045-02 3300 XL Extension Cable

Key Parameters and Features

Core Features & Advantages

• Complete Interchangeability: The module's standout feature is its full interchangeability within the 3300 XL system. Probes, extension cables, and Proximitor Sensors can be replaced without the need for individual matching or bench calibration, significantly simplifying maintenance and reducing spare parts inventory .

• Superior Environmental Protection with Option 02: The "-02" suffix indicates the inclusion of pre-installed silicone rubber connector protectors. These protectors eliminate the need for self-fusing silicone tape or heat-shrink tubing at the connection point, providing a reusable environmental seal that prevents fluid contamination and moisture ingress—essential in oily or humid industrial environments .

• Robust ClickLoc Connector Design: The cable features patented ClickLoc connectors with gold-plated brass construction. These connectors provide a locking mechanism that prevents loosening from vibration, ensuring a reliable, long-term electrical path. The connectors are designed to be tightened finger-tight, with a tactile "click" confirming proper engagement .

• Signal Integrity and EMI Protection: The cable's 75 Ω triaxial construction with foil shielding ensures high signal-to-noise ratio and strong immunity to electromagnetic interference. This allows stable transmission of low-level analog signals for both static (position) and dynamic (vibration) measurements .

Typical Applications

The 330130-045-02 is widely used for critical rotating machinery monitoring across various heavy industries:

• Power Generation: Radial vibration measurements on fluid-film bearing turbines 

• Oil & Gas: Thrust (axial) position monitoring in high-speed compressors 

• General Industry: Keyphasor and speed sensing applications, integration with 3500/42M or 3500/45 monitoring racks 

Frequently Asked Questions (FAQ)

Q1: What is the primary function of the 330130-045-02?

A: It is an extension cable that connects a 3300 XL 8 mm proximity probe to a Proximitor Sensor, maintaining signal integrity for vibration and position monitoring in rotating machinery .

Q2: What does the "-045-02" suffix in the model number mean?

A: The "-045" indicates a cable length of 4.5 meters (14.8 feet). The "-02" indicates the cable option is standard with connector protectors pre-installed .

Q3: What is the advantage of the connector protectors?

A: The connector protectors provide a reusable environmental seal that prevents fluid contamination and moisture ingress. They eliminate the need for self-fusing silicone tape or heat-shrink tubing at the connection point, making installation faster and more reliable .

Q4: Can this cable be used with 5mm or 11mm probes?

A: The 3300 XL 8mm system, including the 330130-045-02, is electrically tuned for 8mm and 5mm probes only. It is not compatible with 11mm or 25mm transducer systems due to differences in electrical impedance and scale factor .

Q5: What is the minimum bend radius for installation?

A: The minimum cable bend radius is 25.4 mm (1.0 inch). Exceeding this limit can damage the cable's internal conductors and degrade signal quality .

Q6: How do I verify the correct total system length?

A: The sum of the extension cable length and the probe lead length must equal the Proximitor Sensor system length. For example, a 9-meter Proximitor works with an 8-meter extension cable and a 1-meter probe .

Q7: What is the operating temperature range?

A: The cable operates from -51°C to +177°C (-60°F to +350°F). This extended range makes it suitable for extreme industrial environments .

Q8: How should the extension cable be routed?

A: Route the extension cable away from power lines and noise sources. Maintain a minimum distance of 12 inches from AC power cables and motor leads. Never run sensor cables in the same conduit as high-voltage wiring. Use mounting clips to secure the cable and avoid stress on the connections .
