CALIBRATION METHOD OF STATIC DATA thermocouples and DEVICE FOR ITS IMPLEMENTATION

摘要

1. A method for the calibration of the static characteristics of a thermocouple comprising the steps of simultaneously tariruemuyu heated thermocouple and the reference temperature sensor, changing the heating temperature in the continuous operating temperature range of the thermocouple, characterized in that from the beginning of the range of operating temperatures thermocouple formed intvervaly predetermined measurement accuracy sequentially as increasing the heating temperature, within the operating temperature range tariruemoy termopary.2. A method of calibration of the static characteristic of the thermocouple according to claim 1, characterized in that at the beginning of each interval a predetermined accuracy of measurement simultaneously stored tariruemoy Seebeck thermocouple and the reference temperature sensor readings, determine the gain and the calculated temperature by formulas sootvetstvennogde K, t, V, tp V - respectively gain, temperature, thermoelectric tariruemoy thermocouple interval starts a predetermined measurement accuracy, and the estimated temperature thermopower tariruemoy thermocouple signal determined mo the modulus of the difference between the estimated temperature and the indication of the reference transmitter and begin formation of the next interval specified accuracy izmereniy.3 module when exceeding the threshold signal difference signal. An apparatus for the calibration of the static characteristics of the thermocouple comprising a heating furnace in which placed tariruemaya thermocouple and temperature meter, characterized in that it comprises a measurement portion conditioners, and outputs tariruemoy thermocouple temperature measuring instrument are respectively connected to first and second inputs of each of the serially connected formirova
