Filed:

Jun 15, 1981

Appl. No.:

6/388695

Inventors:

Alfred E. Wells - Rochelle Park NJ
James H. Casillo - Towaco NJ

Assignee:

Thermo Electric Co., Inc. - Saddle Brook NJ

International Classification:

H01L 3528

US Classification:

136221

Abstract:

A fast response thermocouple probe is formed from two strips of different resilient thermocouple metals. The strips each have a bowed portion with the bowed portions overlapping and crossing each other at a spot welded junction point. The ends of each strip are connected together and engage a body member so that the bowed portions are spaced from the body. The strips are bent to form leaf springs thereby allowing for a resilient junction.
