ExperTune's PlantTriage Control System Monitoring Software diagnoses the health of instruments, valves and controls

ExperTune’s PlantTriage Control System Monitoring Software now has tools to diagnose the health of instruments, valves and controls.

For years, ExperTune’s “Control Loop Health” approach has identified problem control loops based on technical and economic factors. Several new tools provide more specific performance metrics and diagnostics for each control loop component: the instrument, the valve and the controller.

The Valve Health measurement combines information about control valve sizing, application and mechanical performance to give an overall picture of the valve’s health. PlantTriage’s “context-sensitive drill-down” also provides the next level of detail, including measures of each specific aspect of performance, such as “percent valve stiction”.

Sensor Health uses real-time data to look at common symptoms of instrumentation problems. The Controller Health tools focus on aspects of actual control performance, including variability, inability to hold setpoint and dynamic response.
