WebThis set of Heat Transfer Multiple Choice Questions & Answers (MCQs) focuses on “Response of a Thermocouple”. 1. “The response of a thermocouple is defined as the time required for the thermocouple to reach the surrounding temperature when it is exposed to it”. a) True. b) False. WebMay 15, 2024 · For example, if a thermocouple penetrates a medium with high thermal capacity and rapid heat transfer, the effective response time would approach that of the thermocouple itself (its intrinsic response time). But if the thermal properties of the medium are poor, still air for example, the response time can be 100 times greater.
