International practical temperature scale is with the temperature designated value of some reproducible equilibrium states (defining fixed point), and in the world
Based on the standard interpolation instrument indexed on these fixed points of practical temperature scale.Nineteen sixty-eight international practical temperature scale is divided into three temperature
Area defines these temperature with standard platinum resistance thermometer, standard platinum rhodium (10%) platinum thermocouple and Planck's law of radiation respectively
Temperature value in area.
The core component of the quartz crystal thermometer of the prior art is resonance type quartz crystal crystal oscillator, working mechanism with
Traditional temperature sensor (platinum resistance thermometer, thermocouple thermometer etc.) is different, and working mechanism is " resonance ", is not by dividing
" resistance " or " electromotive force " that the warm-up movement of son generates.
The quartz oscillator of the prior art, frequency --- temperature characterisitic are one quite close to the multinomial three times of straight line
Formula curve；A, b, c are respectively one, two, three polynomial coefficient, related with the type of cut of quartz wafer and the vibration shape.
The quartz crystal thermometer of the prior art at least 2 quartz oscillators, one is that temperature is 0 DEG C of benchmark
