Due to low thermal diffusivity

the temperature of armoured sensor sensitive parts lags behind that of the measured medium

resulting in a large dynamic measurement error.Thus

the sequential function method based on reverse heat-conduction problem was applied to dynamically measure the temperature sensors

on the basis of the sensor output variation against time.Then the heat flux between surface and medium can be estimated

and the medium temperature can be calculated.The simulation results show that

the temperature measurement can be corrected dynamically by the sequential function method.Through parameter optimization

the temperature change of the measured medium can be traced quickly

so the response time of dynamic temperature measurement is sharply shortened.
