Eddy-Current and Pressure Signal Processing Features
The 3500/77M monitor receives dynamic cylinder pressure signals from approved Bently Nevada pressure transducers and performs signal conditioning before measurement calculation. Moreover, the module applies TSI-oriented monitoring methods by validating sensor signal behavior and maintaining measurement accuracy for rotating machinery analysis.
The module supports compressor mechanical evaluation through pressure waveform processing. Therefore, it can calculate rod load related parameters, including peak compression, peak tension, and rod reversal conditions. The signal processing architecture is designed for separation of pressure measurement channels and suppression of measurement interference during machine operation.
