Sensor signal acquisition and SIL 3 certified Machine Protection of all Rotating Equipment
Machine protection is based on vibration and critical parameters such as dynamic rod/shaft position and dynamic pressure.
Signal plausibility checks to avoid false alarms and warnings
Specialized signal processing avoids false warnings caused by broken wires, loose sensors, and other electrical failures.
Automatic 10-minute ring buffer for detailed root cause analyses (RCA)
Continuously recorded uncompressed signal data of all connected sensors (hardwired and DCS connected) are available for detailed root cause analyses. This ring buffer is automatically saved in case of an alarm or at every start/stop, and when the user initiates it.
Early Failure Detection
PROGNOST®-NT automatically recognizes changing machine operating conditions and adjusts the monitoring thresholds to avoid false warnings caused by variables such as changing load conditions.
Reliable and meaningful piston rod position for reciprocating compressors
Conventional monitoring methods use rod drop measurements for wear monitoring purposes only. PROGNOST®-NT uses the dynamic piston rod position for reliable rider ring wear calculation and to monitor the mechanical condition of piston rod, piston and crosshead connections.
Automated p-V diagram analyses
PROGNOST®-NT processes above all the online p-V diagram with dedicated analyses to optimize machinery performance and to detect leak sources finally suction/discharge valves, packing, or piston rings. Furthermore, it calculates dynamic piston rod loads to provide an early warning of overload.
Pattern recognition with fully integrated diagnostic database
Each PROGNOST®-NT system automatically generates and saves new damage patterns if component failures occur. Finally all major failures are analyzed and integrated as own failure patterns into the systems’ diagnostic database like the more than 150 failure patterns derived from hundreds of machines with millions of operating hours.
