Bently Nevada 330130-080-00-00 3300 XL Standard Extension Cable

Description

Option 080 (8.0 meters cable length) and Option 00 (standard unarmored cable with standard connectors) specify the configuration for this 3300 XL standard extension cable — 330130-080-00-00. This configuration utilizes a 75 Ohm triaxial fluoroethylene propylene (FEP) insulated cable to link the proximity probe to the Proximitor sensor. It includes standard gold-plated ClickLoc miniature coaxial connectors on both ends without pre-installed connector protectors or external stainless steel armor. The total length of 8.0 meters is selected for transducer configurations where the combined length of the proximity probe and the extension cable must match the required total system length of 9.0 meters (with a 1.0-meter probe).

The FEP insulation provides resistance to lubricating oils, industrial solvents, and moisture in process environments at operating temperatures up to 177 degC. Unlike sibling variants such as the 330130-080-01-00 (which features stainless steel protective armor) or the 330130-080-02-00 (which features pre-installed connector protectors), this unarmored standard version provides maximum routing flexibility and a minimal cable diameter of 3.70 mm. This design facilitates installation through narrow conduit runs or tight bends where mechanical abrasion is not a primary concern. The standard gold-plated click-type connectors provide electrical connection and prevent loosening under vibration without requiring special installation tools.

Features

• Option 080 specifies an 8.0-meter (26.2 feet) physical cable length.
• Option 00 standard unarmored configuration with 75 Ohm triaxial FEP insulation.
• ClickLoc miniature coaxial connectors feature gold plating and a finger-tight locking mechanism.
• FEP cable insulation resists degradation from exposure to lubricating oils and process chemicals.
• Supports standard operating temperature range from -51 degC to +177 degC.
• Maintains a constant system capacitance of 69.9 pF/m to match Proximitor calibration requirements.

Applications

Typical industrial applications for this standard extension cable include rotating machinery monitoring in sectors such as power generation, petrochemicals, oil and gas, and water treatment. It is used to connect 3300 XL 8 mm proximity probes to Proximitor sensors for measurements of:

• Shaft radial vibration
• Axial position (thrust displacement)
• Phase reference (Keyphasor)
• Eccentricity and speed

Installation Guidelines

Observe the following installation guidelines for the extension cable to maintain measurement integrity:

• Verify that the combined length of the extension cable and proximity probe matches the calibration requirements of the Proximitor sensor (typically a total length of 9.0 meters).
• Maintain a minimum bend radius of 25.4 mm (1.0 in) throughout the cable routing to avoid internal conductor damage or impedance alterations.
• Use caution when pulling unarmored cable through conduit to prevent sharp bends or snagging on sharp edges.
• Ensure ClickLoc connectors are joined finger-tight; a physical "click" indicates proper seating and locking. Do not use pliers or other mechanical tools on standard ClickLoc connectors unless mating with non-XL stainless steel connectors.
• Isolate the coaxial connectors from potential machine grounding paths by routing the connections within dedicated junction boxes or using non-conductive sleeves.

Compliance and Certifications

This configuration (Option C: 00) is classified as not requiring specific agency approvals. It does not carry hazardous area certifications such as ATEX, IECEx, or CSA. For applications within explosive or hazardous atmospheres, please select the Option 05 variant (e.g., 330130-080-00-05).
