Abstract For industrial-type platinum resistance thermometer (IPRTs), the most-used interpolation model (resistance versus temperature ) is based on the Callendar- Van Dusen (CVD) equation,and standard platinum resistance thermometer (SPRT) with interpolation equation based on the ITS-1990 .There are difference between CVD equation and ITS-1990.The experiment results show, it is feasible to use ITS-1990 interpolation methords for IPRTs.There are more uniformity and accuracy with ITS-1990 than that with CVD equation.
