The 16925 cable assembly is designed to facilitate the high-frequency signal propagation required for accurate rotor dynamics observation. To ensure data integrity, the physical installation must prioritize the maintenance of the nominal -10 VDC gap voltage target for eddy-current probe interfaces. Any deviation in the impedance of the signal path, caused by damaged insulation or improper shield termination, can introduce artifacts into the vibration waveform. Cross-talk suppression is achieved through the integrated shielding layer; therefore, it is mandatory that the shield be terminated correctly at the instrumentation ground to prevent ground loops that interfere with phase measurement accuracy.
Q: Is the 16925 cable assembly compatible with non-Bently Nevada transducers?
A: The 16925 series is factory-calibrated for specific Bently Nevada transducer interfaces. Use with third-party sensors may result in impedance mismatches, impacting the frequency response and signal-to-noise ratio of the monitoring system.
Q: What are the requirements for cable termination?
A: The assembly must be terminated in accordance with the specific monitoring module's terminal block configuration. Ensure all connections are tight to prevent resistive heating and signal fluctuation.
