Configured for RF signal transmission in 3300 XL Proximitor Sensor networks, the Bently Nevada 330130-080-00-05 (330130 Extension Cable) provides direct physical/electrical execution. It serves as the calibrated passive connection linking an eddy-current proximity probe to a remote Proximitor sensor, facilitating continuous analog measurement loops without introducing impedance discontinuities.

Eddy-Current Probe Scaling & Gap Voltage Validation
The physical geometry and materials of the 330130-080-00-05 extension cable are specifically engineered to maintain precise electrical parameters required for proper eddy-current probe scaling. This control over coaxial circuit capacitance and inductance prevents signal degradation across the 8.0 m path. Consequently, the transducer loop can perform accurate gap voltage validation targeting nominal -10 VDC levels, which is required to capture reliable vibration and position data across machinery rotor dynamics profiles.
Frequently Asked Questions
Q: How does the choice of an 8.0 m extension cable affect overall sensor loop matching?
A: Proximitor systems are calibrated for fixed total electrical lengths, typically 5.0 m or 9.0 m. An 8.0 m extension cable must be matched with a 1.0 m proximity probe to meet the total 9.0 m design parameter; mixing mismatched lengths disrupts the linear scale factor.
Q: Can this cable be altered or cut to fit constrained field enclosures?
A: No. Altering the physical length changes the cumulative capacitance and electrical length of the coaxial line. Trimming will void the factory calibration and cause systemic measurement errors in the displacement loop.
Field Installation Guidelines
- Ensure the total electrical length of the probe and extension cable correctly matches the specific system configuration requirements marked on the Proximitor sensor housing.
- Observe the minimum static bend radius limitation of 25.4 mm during cable installation to prevent mechanical kinking or damage to the internal dielectric core.
- Adequately insulate and isolate all subminiature coaxial connectors using proper terminal boots or self-fusing tape to prevent ground loops caused by structural contact.
- Route the non-armored cable through grounded protective conduits to minimize external electrical noise and cross-talk interference from high-voltage machinery wiring.
