The Bently Nevada 330130-040-03-00, also cataloged as the 330130 Extension Cable, operates as a dedicated hardware component for RF signal transmission within 3300 XL Proximitor Sensor networks. It acts as the electrical link connecting a proximity probe to a remote transducer module, facilitating continuous gap voltage monitoring without introducing phase errors or uncompensated impedance mismatches into the measurement loop.

The mechanical integrity of rotating machinery relies on consistent eddy-current probe scaling. The 330130 extension cable maintains tight impedance matching to prevent signal attenuation and phase shifts over its 4.0 m length. This shielding configuration supports gap voltage validation targeting a nominal -10 VDC baseline, ensuring that the Proximitor sensor translates distance deviations into clean linear voltage tracking without cross-talk interference from neighboring high-current lines.
Q: Does the installation of the connector protectors alter the electrical characteristics or the total system length optimization?
A: No. The connector protectors provide purely physical isolation and sealing for the coaxial junctions. They do not alter the electrical length, capacitance, or 75.0 ohm characteristic impedance calibrated for the 3300 XL system.
Q: What is the mechanical limitation regarding cable routing and minimum bend radius for the armored option?
A: The armored jacket variant mandates a minimum static bend radius of 25.4 mm. Exceeding this threshold risk mechanical deformation of the inner coaxial core, which alters local capacitance and degrades signal linearity.
