MULTICHANNEL TEMPERATURE SENSOR Russian patent published in 2021 - IPC G01K7/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to thermoelectric devices for measuring temperature; it can be used to record the temperature of high-speed thermodynamic processes, such as the combustion of explosives and plasma fuel systems (PFS). A multichannel temperature sensor is substrate 1, for example, made of sitall with tracks applied to it, for example three, from contacting layers of metal pairs 2 and 3 (for example, copper and nickel) capable of producing thermo-electromotive force (EMF) with the formation of a hot junction zone with a cross-sectional area of S1, S2 and S3, respectively, with S1<S2<S3 or S3<S2<S1.

EFFECT: provision of high-speed performance when recording temperature profiles of high-speed thermodynamic processes.
