Bently Nevada 330130-045-03-00 3300 XL Standard Extension Cable

Description

Armored FEP coaxial cable with pre-installed connector protectors specifies this 4.5-meter configuration—the 330130-045-03-00 is a 3300 XL standard extension cable engineered for industrial machinery protection systems. It establishes the electrical connection between a 3300 XL 8 mm proximity probe and a 3300 XL Proximitor sensor, providing a calibrated transmission path for shaft vibration, axial position, and speed monitoring.

Unlike the standard unarmored 330130-045-00-00 variant, this model (Option 03) features integrated stainless steel armor with an outer FEP jacket, protecting the internal coaxial core against mechanical wear, abrasion, and aggressive fluid exposure. Furthermore, it incorporates pre-installed fluorosilicone connector protectors on the female connector end to prevent moisture, dirt, and chemical ingress in hazardous or oily environments.

Features

• Option 045 specifies a 4.5-meter (14.8 feet) total cable length, matching the overall system calibration requirements of 5-meter or 9-meter transducer chains.
• Option 03 provides a stainless steel protective armor with a FEP outer jacket to shield the core coaxial conductor from abrasive industrial environments.
• Pre-installed fluorosilicone connector protectors on the female end seal the connection point against oil, moisture, and particulate contamination.
• Golden ClickLoc coaxial connectors ensure a low-resistance, secure electrical and physical connection that resists loosening under machine vibration.
• Option 00 specifies that no special agency approval package is selected for this specific standalone item.
• FEP jacket insulation supports a continuous operating temperature range of -52 degC to +177 degC.

Applications

Typical application scenarios for this extension cable include:

• Steam and gas turbine rotor vibration monitoring
• Centrifugal and axial compressor shaft displacement and position tracking
• Gearbox shaft dynamic motion analysis
• Hydroelectric generator shaft alignment and vibration telemetry
• Industrial pumps, fans, and cooling tower rotating element protection

Installation Guidelines

Proper installation of the extension cable is critical for long-term vibration measurement stability and noise immunity:

• Always hand-tighten the miniature coaxial gold ClickLoc connectors. Do not use pliers, as excessive torque can damage the delicate internal contacts.
• Ensure that the connector protector is fully seated over the female-to-male connection point to prevent oil, moisture, and chemical contamination.
• Maintain a minimum bend radius of 25.4 mm (1.0 in) for the armored cable during routing to avoid kinking the stainless steel casing or damaging the inner FEP core.
• Shielding must be grounded properly at the monitor rack or terminal block; ensure the extension cable shielding remains isolated from machine ground along its run.
• Route the cable through dedicated conduit or trays to avoid proximity to high-voltage AC lines, which can induce noise on the transducer signal.
