Description
1. Product Title
Bently Nevada 330180-91-05 – 3300 XL Proximity Sensor Extension Cable
2. Product Overview
The 330180-91-05 is a dedicated extension cable belonging to Bently Nevada’s industry-standard 3300 XL eddy current proximity transducer system. It serves as the critical transmission medium connecting the proximity probe and the vibration monitoring system’s front-end interface module, transmitting high-frequency displacement signals generated by the non-contact eddy current probe in rotating machinery condition monitoring systems. This component resolves wiring distance limitations between on-machine probes and control room rack-mounted monitoring equipment, maintains stable impedance matching throughout the signal loop, and minimizes electromagnetic interference and signal attenuation during long-distance transmission. Reliable signal delivery from 330180-91-05 directly guarantees the accuracy of shaft vibration, axial thrust position and rotor eccentricity measurements, effectively preventing false alarms and measurement deviations in turbine and rotating equipment protection loops.
