Based on the analysis of principle and structure, the soft sensing method on in wall temperature during flash heat transfer in closed chamber is studied in this paper. And the soft sensing model on in-wall temperature during flash heat transfer is given. At the same time, three kinds of solutions for the model and a case are given. It is concluded that the in wall temperature during flash heat transfer in closed chamber can be measured by adopting soft sensing method and selecting the slowly changing temperature as the secondary variable. As a result, the cost of the measuring system can be decreased.
