Configured for specific electrical length matching in machinery protection networks, the Bently Nevada 330130-085-13-CN (330130 Standard Extension Cable) provides direct physical/electrical execution. The coaxial assembly links an 8 mm proximity probe to a 3300 XL Proximitor Sensor, maintaining loop impedance boundaries required to transmit high-frequency eddy-current displacement signals back to the central processing rack.

Model Nomenclature Breakdown

• 330130: 3300 XL Standard Extension Cable

• -085: Cable length option (8.5 meters / 27.9 feet)

• -13: Connector and cable option (Stainless steel armor with connector protector)

• -CN: Agency approval option (China RoHS and local hazardous area certification)

Dimensional and Electrical Parameters

Eddy-Current Probe Scaling and Loop Tuning

The hardware directly affects eddy-current probe scaling by introducing a fixed capacitive and inductive load to the RF oscillator circuit. To achieve correct gap voltage validation matching the -10 VDC baseline at physical center, the overall physical system length (probe plus extension cable) must accurately total 9.0 meters when paired with a 0.5-meter probe, or 10.0 meters if specified by alternative system tuning. Proper installation maintains strict cross-talk suppression by shielding the core conductor within a braided metallic wrap enclosed in stainless steel armor, preventing overlapping electromagnetic fields from adjacent rotor dynamics monitoring channels from introducing signal noise.

Field Routing and Connection Specifications

Physical installation requires strict adherence to bend limits and grounding protocols to protect signal transmission.

1. Route the armored cable length from the proximity probe junction box to the Proximitor enclosure using dedicated physical conduits or tray networks.

2. Maintain a minimum bend radius of 25.4 mm throughout the cable run to avoid fracturing the internal coaxial shielding layers.

3. Join the miniature coaxial ClickLoc connectors by pushing and twisting the terminal ends together until fully seated. Slide the pre-installed connector protector over the junction to eliminate moisture ingress.

4. Insulate the extension cable armor from structural machine metals. The system shield must remain isolated from ground until its termination point inside the Proximitor Sensor housing.

Logistics Frame and Packaging

Component Performance FAQ

Q: Can a 330130-085 extension cable be cut or spliced to fit localized enclosure distances?

A: No. The extension cable length is precisely matched to provide the specific capacitance required for factory eddy-current probe scaling. Cutting or splicing the cable alters the electrical length, making gap voltage validation at -10 VDC impossible and causing severe calibration drift across the linear range.

Q: Is this extension cable compatible with older non-XL 3300 series 8 mm proximity probes?

A: Yes. The 3300 XL extension cable is physically and electrically backwards compatible with standard 3300 series 8 mm probes and Proximitor Sensors. However, mixing components may limit the system to the temperature and linear specifications of the older hardware.

Q: Does hot-swapping the extension cable damage the linked 3500 rack channels?

A: No. Disconnecting the cable while the system is live is a safe field operation because the cable contains no active electronic components. The monitoring module will instantly report a transducer fault (NOT OK status) due to the open circuit loop, but no hardware degradation occurs.
