Sensor for finding physical characteristics of fluid or solid zone from thermal measurements, comprises sandwich with heated central layer and flux and temperature gauges in adjacent layers

摘要

The sensor (1) has a three layer sandwich configuration. The central layer has a heating element (32) and temperature sensor (31) which may be combined and is located between an upper layer (2) which has a heat flux meter (23) and temperature sensor (21) and a lower layer (4) also equipped with heat flux meter (43) and temperature sensor (41). The central and adjacent layers are each contained within thermally conducting coatings (5) Independent claims are made for heat supply and data processing systems, methods associated with the use of the sensor, and also for an application to the determination of frying oil characteristics
