A Study on the Temperature Accuracy due to Conditions of Thermocouple Installation

In the equipments of industrial plant and marine engine, an exact temperature measurement is indispensable. Temperature measurement errors are induced by electrical and heat errors, and the insufficient immersion length of thermowell exerts an important effect to the haet error. In this paper, the author analyses the relation between temperature errors and the rate of immersion length to outside diameter (L/D) in order to reduce the heat errors.
