7 November 2012Condition monitoring of reciprocating compressor using FBG-based sensors in petrochemical industry
Real-time, on-line measurement of key physical parameters as well as their variations is the most crucial problem for
safety running of reciprocating compressors in petrochemical plants. In this paper, a method for condition monitoring
and fault diagnosis of reciprocating compressor based on FBG sensors is proposed. A fiber optic accelerometer is
demonstrated, which is used for detecting the vibration of crankcase, crosshead and cylinder of the compressor. FBGbased
temperature sensors are used to monitor the variation of the suction/vent valve temperature. A monitoring system
included hardware and software for the reciprocating compressors is developed and applied in a petrochemical plant.
