Monitoring in LDPE service Monitoring of machines in LDPE (Low Density Polyethylene) service demands a highly adaptable and reliable technology. PROGNOST®-NT is the leading system for monitoring Booster/Primary and Secondary Compressors [...]
The PROGNOST®-Navigator is a 12 inch touch panel with TFT color wide screen display. Designed for field data monitoring. The PROGNOST®-Navigator is the intelligent response to increasingly complex processes and instrumentation status of machines and plants. It displays data of the monitored machine trains as well as the Machine Protection System (MPS) itself. This enables operators a holistic condition overview.
“Intelligent Machine Monitoring” is a video production from experts for experts. Viewers learn basics of signal analyses as well as advanced topics to improve the results of their daily work. Enjoy the movies and feel free to share your thoughts in the comments section. We are also open for your suggestions for topics to be explained and discussed.
As shown in previous movies there are different probes to monitor the compressor behavior. In the video we would like to talk about the proximity probe to monitor the vertical piston rod displacement. This probe is installed close to the packing and could be installed above or below the piston. Additionally a second probe per piston could be installed to monitor also the horizontal displacement. During the video we will talk about functionality and different analyses for this sensor signal.
Condition monitoring can substantially reduce the cost of consequence by avoiding catastrophic failures and reducing the frequency of incidents by providing realtime and continuous diagnoses of bad actors and all relevant components.
