Description
Bently 330130-80-00-00
Technical Specifications
- Product Series: 3300 XL 8mm Extension Cable
- Part Number: 330130-80-00-00
- Cable Length: 8.0 meters (26.2 feet)
- Cable Type: Standard cable
- Connector Type: Miniature coaxial ClickLoc connectors at both ends
- Agency Approval: Not required
Functional Features
- Signal Transmission: Transmits the high-frequency signal from the probe to the Proximitor with minimal attenuation.
- System Compatibility: Compatible with all 3300 XL 8mm proximity probes and Proximitor sensors.
- Low Noise Design: Shielded construction minimizes electromagnetic interference (EMI) and radio frequency interference (RFI).
- Extended Cable Length: The 8.0 meter cable length is designed for installations where the Proximitor is mounted at a significant distance from the probe.
Application Scenarios
Used in conjunction with 3300 XL 8mm proximity probes and Proximitor sensors to form a complete 9.0 meter system (when combined with a 1.0 meter probe cable). Common applications include steam turbines, gas turbines, centrifugal compressors, pumps, fans, and gearboxes in power generation, petrochemical, refining, and steel industries. The standard cable construction is suitable for installations where the cable is routed through conduit or cable trays with minimal mechanical stress.

- Minimum Bend Radius: 25.4 mm (1 inch)
- Characteristic Impedance: 75Ω ± 5%
- Capacitance: 69.9 pF/m (21.3 pF/ft) typical
- DC Resistance (Core-to-Core): 1.76Ω ± 0.26Ω at 8.0 meters
Material Composition
Fluorinated ethylene propylene (FEP) insulation, shielded copper braid, and gold-plated ClickLoc connectors.
Structural Characteristics
Coaxial cable with miniature ClickLoc connectors at both ends. The cable is designed for routing through conduit or cable trays in industrial environments.
Working Principle
The extension cable transmits the high-frequency signal generated by the probe coil to the Proximitor, where it is demodulated and converted into a DC voltage output proportional to the gap distance.
Installation Requirements
Connect the probe-side connector to the probe cable and the Proximitor-side connector to the Proximitor sensor. Ensure the connectors are finger-tight plus 1/8 turn using pliers. The total system electrical length (probe cable plus extension cable) must match the Proximitor rating.
Usage Notes
Avoid sharp bends or kinks in the cable during routing. Ensure the cable is not exposed to temperatures exceeding the rated operating range. Handle the cable carefully to avoid damage during routing.
