【Abstract】 This paper presents the experimental study of dynamic characteristics of temperature transducers by using a microcomputer based data acquisition system in combination of electric heating in laboratory. It is proven that this method is simple, convenient, and practical, and it is suitable for not only temperature transducers with big time constant, but also those with sharp property variation.更多还原
