Abstract

PURPOSE:To simplify adjusting performance as well to heighten reliability, by adjusting on compensation for offset voltage and current of operation amplifier, influence caused by circumference temperaure of cold junction of thermo electric couple and etc., at one place. CONSTITUTION:Correction for taking off influence caused by circumference temperature of cold junction on thermo electric couple 2 which works as temperature sensor for detecting temperaure on evaporating surface, is performed by branch circuit A and semifixed resistor 9 connected to A, and at the same time, also performs compensation adjustment on offset voltage and current of operation amplifier 11 and temperaure drift, etc. In case to perform correction on influences caused by circumference temperature at cold junction and offset, etc. together, electric potential at point a should be adjusted against divided potential point c by adjusting semi-fixed resistance 9, under consideration on voltage variation in combination of both influences.
