Primary circuit valves: use case

Context

The valve was instrumented and tested on a test bench. Two types of cycles, full and partial strokes. Anomalies were artificially produced by over-tightening certain parts of the valve.

Need

The customer wanted to detect deficient cycles when certain parts were over-tightened.

Solution

DiagFit detected the deficient cycles.

Results

TNR = True negative rate

TPR = True positive rate

(These are the detection rates for healthy and non-healthy data respectively)

Complete cycles: TNR 83% and TPR: 92

Partial cycles: TNR 98% and TPR 45%.
