DIFFERENTIAL TEMPERATURE SENSOR

摘要

Sensor including a substrate, an assembly of thermoelectric layers including at least one first and one second junction of a thermocouple, at least one first and one second connection pads arranged to transfer heat respectively to each first and each second junction, a support member (2) of the substrate (3) intended to be connected to the hot source (Sc) and to the cold source (Sf), first and second metal connectors arranged to electrically connect the support member (2) respectively to each first and each second connection pad, the support member (2) including a thermal conductor configured to transfer heat from the hot source (Sc) to the first metal connector, and to transfer heat from the second metal connector to the cold source (Sf).

1. A differential temperature sensor between a hot source and a cold source, including:
a substrate; an assembly of thermoelectric layers arranged on the substrate, the assembly including at least one first junction of a thermocouple on one side of the assembly, called hot side, and at least one second junction of the thermocouple on an opposite side of the assembly, called cold side; at least one first connection pad and at least one second connection pad configured to transfer heat respectively to the at least one first junction and to the at least one second junction; a thermally-insulating support member configured to support the substrate, said support member being intended to be connected to the hot source and to the cold source; a first metal connector and a second metal connector configured to electrically connect said support member respectively to the at least one first connection pad and to the at least one second connection pad; wherein said support member includes:
a first thermal conductor configured to transfer heat from the hot source to the first metal connector, anda second thermal conductor configured to transfer heat from the second metal connector to the cold source.
