The Bently Nevada 330130-080-01-05, also cataloged as the 330130 Armoured Extension Cable, operates as a dedicated hardware component for RF signal transmission within 3300 XL Transducer System networks. It acts as the protective, low-attenuation electrical path linking an 8.0 mm proximity probe to a remote processing Proximitor sensor, enabling high-frequency eddy-current displacement execution without altering the fixed loop impedance parameters.

The internal 75 ohm coaxial core of the 330130-080-01-05 extension cable is physically calibrated to ensure that cumulative system capacitance matches the tuned criteria of the 3300 XL platform. This precision is required to stabilize eddy-current probe scaling for target 8.0 mm tip assemblies. Preserving electrical length uniformity prevents high-frequency rolloff and signal attenuation across the 8.0 m line, enabling exact gap voltage validation targeting standard -10 VDC operational baselines for machinery rotor dynamics monitoring.
Q: Why must the combined electrical length of the proximity probe and extension cable remain constant?
A: The Proximitor sensor is factory-calibrated to drive an exact total circuit length (such as 5.0 m or 9.0 m loops). Introducing a mismatched cable configuration changes the total capacitance, which shifts the linear scale factor and corrupts physical gap voltage tracking.
Q: How do long field wiring runs between the Proximitor sensor and monitor affect high-frequency outputs?
A: While the 330130-080-01-05 interfaces directly with the probe, the subsequent field lines extending to the monitor panel are capped at 305 m. Exceeding this distance creates electrical signal rolloff at high frequencies due to line capacitance.
