Simulation of a Shielded Thermocouple

Abstract

A shielded thermocouple is a measurement device used for monitoring the temperature in chemically, or mechanically, hostile environments. The sensitive parts of the thermocouple are protected by a shielding layer. In this work we use numerical methods to study the accuracy and dynamic properties of a shielded thermocouple design. Also, we show that by formulating and solving an appropriate inverse problem, we can significantly reduce the errors in the measurement process.
