This paper presents a kind of surface temperature sensors for measuring temperature on inner surface of gun-barrel. Construction and principles of the sensors are introduced. The mathem atical model has been established on the base of heat conduction. The dynamic response characteristics of the sensors are studied. Numerical solutions of typical problems are evaluated by using finite differential method. Some simulative results of dynamic response characteristics are given. Experimental research of a principle model of surface temperature sensors designed specially is done with heating method by a pulse laser. Prelim inary experimental results are given and they are identical with those of numerical evaluation. All the results presented by this paper provide the basis for design and use of this kind of sensors.
