DETECTION OF FLUIDS WITH METAL-INSULATOR-SEMICONDUCTOR SENSORS

A metal-insulator-semiconductor diode sensor (10) having a Pt/Ir alloy electrode (15) is sensitive to and can detect ethylene. An array of metal-insulator-semiconductor diode sensors (30) having varying sensitivity responses can indicate a fault in an electrical transformer by detection of at least...

Zusammenfassung:	A metal-insulator-semiconductor diode sensor (10) having a Pt/Ir alloy electrode (15) is sensitive to and can detect ethylene. An array of metal-insulator-semiconductor diode sensors (30) having varying sensitivity responses can indicate a fault in an electrical transformer by detection of at least one of the key fault gases CO, H2, C2H2, and C2H4.
