Process for calibrating the temperature controlling device of a vertical gradient freeze crystal growing oven comprises taking into consideration correction offsets established during the calibration

摘要

Process for calibrating the temperature control device of a vertical gradient freeze crystal growing oven comprises taking into consideration correction offsets determined by comparing the temperature differences between control temperature emitters and reference temperature emitters with the theoretical temperature differences prescribed for the oven. Process for calibrating the temperature controlling device of a vertical gradient freeze crystal growing oven comprises measuring the temperature at the height of the control temperature emitters (11, 12, 13) after passing through resistance heaters (8, 9, 10) using a reference temperature emitter (5), regulating the power of the resistance heaters to a required temperature value, determining the difference to the temperature of each control temperature emitter, stopping the calibration process after removing the control temperature emitters by comparing the temperature differences between the control temperature emitters and the reference temperature emitters with the theoretical temperature differences prescribed for the oven, and operating the oven taking into consideration correction offsets established during the calibration. An Independent claim is also included for a vertical gradient freeze crystal growing oven.
