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.

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.
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.
