Abstract:
A thermopile sensor with a housing, the thermopile sensor having at least two cold junctions and at least two hot junctions, and with a supporting structure for the cold and hot junctions, characterized in that the thermopile and its supporting structure satisfy the relationship C.sub.K /C.sub.W.apprxeq..lambda..sub.K /.lambda..sub.W,where C.sub.K is the thermal capacity of the cold junctions (11) and their supporting structure;C.sub.W is the thermal capacity of the hot junctions (12) and their supporting structure;.lambda..sub.K is the thermal conductivity in the region of the cold junctions (11); and.lambda..sub.W is the thermal conductivity in the region of the hot junctions (12).
