Rp. Tye et al., TEMPERATURE-MEASUREMENT AND CONTROL - CRITICAL PARAMETERS IN THERMAL-ANALYSIS TECHNIQUES, Journal of thermal analysis, 40(3), 1993, pp. 1009-1016
Several factors in temperature measurement that can affect the precisi
on of melting points and phase-change phenomena are discussed. In many
cases, critical errors may arise in the measurement and control of te
mperatures due to incorrect placement and/or interpretation of the out
put of temperature sensors in the various system types that are in cur
rent use. Advantages can be obtained by using one temperature sensor o
nly for temperature measurement and temperature control in a low mass
infrared gold image furnace for the analytical studies in both the con
stant rate and stepwise isothermal thermoanalytical heating and coolin
g modes. Illustrations of the use of this instrumentation for measurem
ents in both modes are given.
