  • Measuring Temperature Or Quantity Of Heat (AREA)

Abstract

PURPOSE:To realize a quick and high-accuracy measurement of temperature, by calculating via a timer or the like the changing velocity of temperature, the changing acceleration of temperature and other factors and then estimating the final temperature when the heat is balanced based on the prescribed operation. CONSTITUTION:An A/D conversion is given to the electric signal correspoding to the body temperature T which is detected at the temperature detecting part where the thermistor 14 and others are formed into a bridge. The variation factor of the electric signal in a certain time and decided by the timer 10 is calculated by the 1st differentiating circuit 22 to decide the temperature changing velocity dT/dt. In the same way, the temperature changing acceleration d<2>T/dt<2> is decided by the 2nd differentiating circuit 24. Then an operation based on the equation I is carried out by the constant multipliers 26 and 36 which give a multiplication to the heat time constant tau1 at the measuring area of temperature. And thus the high-accuracy estimated temperature when the heat is balanced is displayed quickly on the display device 642 and before lapse of the time (t), where (t) means to time to reach the heat balance state.
