ABSTRACT:
A temperature probe assembly for reading heat gradients occurring in internal combustion engines or other components. The assembly has a plurality of separate thermocouples each having an inner junction mounted in an associated heat contact ring. These rings are mounted in spaced relationship on a tip of a cylindrical probe member to provide axially spaced and multiple heat pick-up points when the tip is mounted in a test bore in the cylinder head near the combustion chamber. Leads from the thermocouples feed to separate gages remote from the engine. The gages collectively detect temperature gradient by reading electric currents proportional to temperature occurring in the thermocouples during engine testing.
