Eddy-Current Signal Scaling and Rotor Dynamics Processing
The 128228-01 module processes displacement and seismic measurement inputs from compatible Bently Nevada sensors. The module supports eddy-current probe scaling functions by conditioning probe signals before system-level vibration analysis.
The input processing path maintains signal accuracy for shaft displacement monitoring and seismic vibration measurement. Moreover, the module supports gap voltage validation using standard -10 VDC target references for eddy-current probe operation verification.
The module architecture supports rotor dynamics monitoring requirements by transferring conditioned vibration data through the rack backplane. Signal processing functions are designed to maintain measurement consistency and reduce interference effects in multi-channel machinery monitoring installations.
