Technical Dossier
The Bently Nevada 330130 Series comprises standard and armored extension cables engineered for use with eddy-current proximity transducer systems, specifically the 3300 XL and 7200 Series proximity probe systems. These cables serve as the signal-transmission link between the proximity probe and the proximitor/driver module, operating in continuous-duty environments across petrochemical refineries, nuclear power stations, LNG terminals, offshore platforms, and rotating machinery installations worldwide.
The 330130 Series is a critical infrastructure component in machinery protection systems (MPS) compliant with API 670 standards. Incorrect cable length or connector type directly affects system calibration, gap voltage, and vibration measurement accuracy. Field replacement of these cables requires strict adherence to OEM-specified part numbers to maintain system certification.
Bently Nevada's extension cable architecture has evolved in parallel with its proximity transducer platform generations. Early 3300 Series systems (introduced in the 1980s) used non-armored, PVC-jacketed cables with standard BNC-style connectors, adequate for controlled machinery rooms but vulnerable in high-vibration or chemically aggressive environments.
The introduction of the 3300 XL platform in the mid-1990s standardized the 330130 cable family with defined impedance characteristics (matched to the 330180 proximitor), temperature ratings up to 121°C (250°F) at the probe end, and optional stainless-steel armor (330130-XX-XX-ALH suffix) for installations subject to mechanical abrasion or rodent damage.
The following SKUs represent the verified, commonly stocked configurations within the 330130 Series. Part number structure: 330130-[Length ft]-[Length m]-[Jacket/Armor suffix].
330130-080-12-CN: Standard extension cable, 80 ft / 12 m, non-armored PVC jacket, standard connectors — the most widely deployed length for general machinery installations.
330130-040-06-CN: Standard extension cable, 40 ft / 6 m, non-armored, for compact machinery trains with short probe-to-proximitor runs.
330130-020-03-CN: Standard extension cable, 20 ft / 3 m, non-armored, used in bench-test setups and short-run field installations.
330130-060-09-CN: Standard extension cable, 60 ft / 9 m, non-armored, intermediate-length configuration for mid-size turbomachinery.
330130-100-15-CN: Standard extension cable, 100 ft / 15 m, non-armored, for installations requiring extended probe-to-rack distances.
330130-080-12-ALH: Armored extension cable, 80 ft / 12 m, stainless-steel interlocked armor, for high-abrasion or high-vibration environments.
330130-040-06-ALH: Armored extension cable, 40 ft / 6 m, stainless-steel armor, compact armored configuration for aggressive environments.
330130-060-09-ALH: Armored extension cable, 60 ft / 9 m, stainless-steel armor, mid-length armored variant.
330130-100-15-ALH: Armored extension cable, 100 ft / 15 m, stainless-steel armor, long-run armored configuration for outdoor or exposed routing.
330130-020-03-ALH: Armored extension cable, 20 ft / 3 m, stainless-steel armor, short armored variant for localized protection requirements.
330130-080-12-CN-02: Standard extension cable, 80 ft / 12 m, non-armored, revision 02 connector specification — used in later 3300 XL rack generations.
330130-040-06-CN-02: Standard extension cable, 40 ft / 6 m, non-armored, revision 02 connector, short-run updated specification.
330130-060-09-CN-02: Standard extension cable, 60 ft / 9 m, non-armored, revision 02 connector, intermediate-length updated specification.
330130-100-15-CN-02: Standard extension cable, 100 ft / 15 m, non-armored, revision 02 connector, long-run updated specification.
330130-080-12-ALH-02: Armored extension cable, 80 ft / 12 m, stainless-steel armor, revision 02 connector — the armored equivalent of the most common non-armored SKU.
330130-040-06-ALH-02: Armored extension cable, 40 ft / 6 m, stainless-steel armor, revision 02 connector, compact armored updated specification.
Extension cables in the 330130 Series are not passive components — their electrical characteristics (capacitance per foot, impedance matching, connector contact resistance) directly affect the calibration of the connected proximitor and the accuracy of gap voltage readings. DriveKNMS applies the following test protocol to all 330130 cables prior to dispatch:
