Title:
SURFACE ACOUSTIC WAVE (SAW) BASED TEMPERATURE SENSING FOR ELECTRICAL CONDUCTOR
Document Type and Number:
WIPO Patent Application WO/2016/106558
Kind Code:
A1
Abstract:
Systems and methods for directly sensing, measuring, or monitoring the temperature of an electrical conductor (31) of a power cable (10), are provided. A surface acoustic wave (SAW) temperature sensor (20) is used that includes a substrate (20S) with a transducer (20T) disposed thereon. The transducer (20T) conducts conversion between an electromagnetic signal and a SAW signal that propagates on the substrate (20S). At least a portion of the substrate (20S) is disposed in thermal contact with the electrical conductor (31) such that the SAW signal varies with the temperature of the electrical conductor (31).
