Serving as a vital link in high-accuracy machinery protection systems, the Bently Nevada 330730-080-00-CN extension cable provides seamless signal transmission for the 3300 XL 11 mm Proximity Transducer System. This coaxial cable is engineered to maintain signal integrity over long distances, connecting the proximity probe to the proximitor sensor without introducing phase shift or calibration drift. Designed specifically to withstand the harsh environments of large rotating machinery, it is optimized for tracking parameters such as radial vibration, axial thrust, and keyphasor references in industrial turbines, compressors, and pumps.
| Parameter | Specification Value |
|---|---|
| Manufacturer | Bently Nevada |
| Model / Article Number | 330730-080-00-CN |
| Product Family | 3300 XL 11 mm Series |
| Cable Length | 8.0 meters (26.2 feet) |
| Cable Armor Option | Standard cable (unarmored) |
| Agency Approvals | Country-specific hazardous location approvals (CN designation) |
| Connector Type | Miniature coaxial male and female connectors |
| Operating Temperature | -51 degC to +177 degC (-60 degF to +350 degF) |
| Minimum Bend Radius | 25.4 mm (1.0 in) |
| Net Weight | 0.140 kg (0.31 lbs) |
| Shipping Weight (Calculated) | 1.000 kg (2.20 lbs) |
The 330730 series cables are uniquely tuned to match the capacitance of the 11 mm proximity probe and sensor. Do not mix this 11 mm extension cable with 3300 XL 8 mm or 5 mm proximity systems. Doing so shifts the overall system capacitance, skewing the proximitor calibration curve away from the target 3.94 V/mm (100 mV/mil) scale factor, which will trigger false machinery vibration alarms.
Because this is the standard unarmored version (-00 option), the cable must not be run freely across machine decks or exposed walkways where it can be crushed or snagged. It is recommended to install standard cables inside dedicated, grounded conduit networks. Keep the cable layout away from high-temperature exhaust lines or turbine casings that exceed the continuous operating rating of 177 degC to prevent dielectric breakdown.
Before mating the coaxial connectors, always clean the gold-plated threads with an approved electronics-grade solvent to remove oil, dust, or moisture. To ensure environmental sealing at the junction point, use a dedicated connector protector kit (e.g., silicone grease and heat-shrink tubing). Hand-tighten the connectors completely plus an additional one-quarter turn using a Bently Nevada connector wrench; avoid standard pliers as they easily strip the gold plating.
CRITICAL WARNING:
Ensure that the machinery monitoring system is bypassed or powered down before disconnecting or replacing the extension cable. Unintentional open-loop faults can trigger machine trips or emergency shutdown (ESD) sequences. Exercise caution regarding residual electrostatic charge on the coaxial core wire.
