The 330130-070-01-CN (330130) is a heavy-duty, armored proximity extension cable designed for the Bently Nevada 3300 XL 8 mm Proximity Transducer System. This cable provides critical signal transmission between a 3300 XL proximity probe and a 3300 XL Proximitor Sensor, allowing for precise static and dynamic measurements of rotating machinery. Widely utilized in high-reliability industrial applications such as fluid-film bearing monitors, compression systems, and high-speed turbine shafts, it plays an important role in delivering data for vibration tracking and Keyphasor speed references. Its robust engineering shields delicate eddy current signals from harsh plant conditions, which enhances monitoring uptime and contributes directly to continuous machinery operation and significant downtime reduction.
The model configuration for the 330130-070-01-CN is defined by the following technical suffixes:
The 330130-070-01-CN architecture is optimized to deliver consistent electrical impedance and low capacitance to prevent signal distortion over long distances. It utilizes advanced gold-plated "click" type coaxial connectors that supply a secure mechanical lock and maintain continuous electrical connection under severe industrial vibration. The internal coaxial cable is wrapped in a rugged flexible armor that protects the internal dielectric material from hot turbine oil and physical stress. This configuration allows complete unit and cabling interchangeability across the 3300 XL platform, eliminating the need for tedious field calibration when replacing individual sensor elements.

Can this extension cable be used directly with a standard non-XL 3300 probe?
Yes. The 330130-070-01-CN is backward compatible and interchangeable with non-XL 3300 series 5 mm and 8 mm transducer components. However, for optimum performance and lowest interchangeability error, a full 3300 XL component setup is recommended.
Is the silicone tape included with the cable suitable for all installations?
Silicone tape is often provided for connector protection in dry conditions to prevent moisture ingress. It is not recommended for applications where the probe-to-cable connection is continuously exposed to or submerged in turbine oil, as petroleum products can degrade the tape over time.
Why is matching the 7.0 meters cable length critical for the Proximitor Sensor?
The Proximitor Sensor is calibrated based on a precise total electrical length (typically 5.0 meters or 9.0 meters). Mismatching a 7.0 meters extension cable with an incorrect probe length or sensor calibration will alter the loop capacitance, introducing severe scale factor errors into your vibration metrics.
Connector Torque and Mechanical Connection
When joining the extension cable to the proximity probe, ensure the gold-plated coaxial connectors are clean and free of debris. The "click" type connectors should be securely locked. For standard finger-tight connections, avoid over-tightening with heavy tools as this can strip the thin gold plating or warp the internal pin, which impacts the nominal 50 Ohm output resistance.
Bend Radius and Routing Constraints
To prevent kinking the inner core conductor and damaging the armor, always maintain a minimum bend radius of 25.4 mm during field routing. Avoid pulling the armored cable around sharp structural steel corners or exposing it to heavy foot traffic without adequate cable trays or channel protection.
Grounding and Noise Separation
The outer stainless steel armor of the 330130-070-01-CN must be kept isolated from the local machine ground along its run to prevent ground loops. Ensure that the signal run is isolated from high-voltage motor power leads, variable frequency drives (VFDs), and heavy switching relays to eliminate electromagnetic noise from coupling into the high-frequency proximity loop.
