Configured for RF signal transmission in 3300 XL Proximitor Sensor networks, the Bently Nevada 330130-045-00-00 (330130 Extension Cable) provides direct physical/electrical execution. It serves as the calibrated electrical link connecting an 8 mm or 5 mm proximity probe to a remote Proximitor module, enabling continuous eddy-current field propagation without introducing uncompensated loop impedance variations.

The mechanical integrity of proximity measurement loops requires strict matching of cable length and electrical properties to ensure precise eddy-current probe scaling. The 330130-045-00-00 extension cable provides the specific capacitance and inductance characteristics required for accurate gap voltage validation, targeting standard -10 VDC operational baselines. This controlled impedance prevents phase lag errors and maintains cross-talk suppression between adjacent high-speed machinery monitoring loops.
Q: Can a 4.5 m extension cable be interchanged with a 4.0 m or 8.0 m cable in a standard 5.0 m or 9.0 m total system setup?
A: No. Proximitor sensors are calibrated for a fixed total electrical length (typically 5.0 m or 9.0 m combined probe and extension cable). Altering the cable length parameter outside specifications shifts system capacitance and invalidates the linear scale factor.
Q: What are the electrical consequences of routing this cable past high-power motor leads without additional armor or conduit?
A: This option utilizes a standard non-armored coaxial shield. Without dedicated outer armor or physical isolation in separate grounded metal conduits, routing near high-current AC lines introduces magnetic coupling that disrupts signal transmission and degrades accuracy.
