A new approach has been developed that is conceptually very simple: to combine the strengths of two different measuring principles without allowing the restrictions to accumulate. Solutions applying this concept are being called “dual sensors,” because two existing sensors-each using different measurement principles-are combined and the signal outputs evaluated together.
Monitoring interactions in a running engine presents a genuine challenge; enormous pressures and temperatures are present, along with multiple moving parts-making the integration of sensors almost impossible.
