Abstract
Abstract High fatigue life thermocouples for use in dynamic stress situations are realized by incorporating the thermocouple components into a thin cylindrical rubber housing. The thermocouple sensor junction is embedded in one end of the housing and its lead wires are wound through a helical groove moulded along the housing''s peripheral surface. A rubber sheath covers the assembly and restrains the lead wires in place.
