Monitoring reciprocating gas compressors with 4-20 mA LPSTM vibration sensors

Many attempts have been made to automate the process through which vibration signals are analyzed to pinpoint a machine fault. Detailed diagnostic vibration analysis is often performed using portable spectrum analyzers that implement Fast Fourier Transform (FFT) mathematics on the vibration signal. In some instances, only a trained analyst can interpret the vibration data, effectively diagnose the problem(s) and make a final determination of the state of the equipment. Still, the success of vibration analysis tools has significantly reduced the cost of vibration monitoring and enabled monitoring of more plant assets.
