Abstract:
A diagnostic monitoring apparatus for continuously monitoring selected operating parameters to indicate to operators the performance and mechanical conditions of a reciprocating gas compressor cylinder having a double-acting piston, the apparatus comprising:a plurality of sensors positioned to monitor selected parameters on or within the cylinder;a plurality of monitored signals generated by said sensors, said monitored signals proportional to the selected operating parameters monitored;sampling means attachable exterior to the compressor cylinder, said sampling means being adapted to trigger said plurality of sensors to monitor the selected operating parameters at equally spaced intervals of movement of the piston;a converter in communication with said sampling means, said converter being adapted to generate output signals proportional to said monitored signals;calculator means in communication with said converter, said calculator means being adapted to analyze said output signals from said converter, said calculator means adapted to compare said output signals to alert parameter ranges, said calculator means issues alarm signals if output signals are not comparable to alert parameter ranges;a transmitter means in communication with said converter and said calculator means, said transmitter means being adapted to transmit output signals and alarm signals to a remote location; andan analysis module attachable exterior to the compressor cylinder, said analysis module contains said sampling means, said analog to digital converter, said calculator means, and said transmitter means.
