Abstract
Thin film gauges are basically resistance temperature detector (RTD) sensors. It is a combination of high conducting (Sensor) and low conducting (Substrate) material. It operates on the simple principle that penetration of heat pulse from the high conducting material to the low conduction one is very small during the time span of the measurement. The present work is focused at design and fabrication of fast response thermocouples and thin film gauges (TFG) in the laboratory. Three types of thermocouples have been fabricated (E-type, E-type (Welding) and K-type) whereas platinum paste is deposited on the insulating substrate (Quartz) for thin film heat transfer gauge. The purpose of this work is to statically calibrate to each handmade heat transfer gauges by using oil bath technique. Both thermocouples and thin film gauges are calibrated under the same experimental conditions. The sensitivity of thin film gauge is found 268.919 % higher than the other sensing materials.
