Abstract

PURPOSE:To halve the number of adjustment steps by simultaneously setting conversion gain and reference value variable ranges of output signals through switching of one circuit. CONSTITUTION:The output of a sensor S is applied to the inversion input of a differential amplifier A. On the other hand, the voltage determining the reference value from a potentiometer RV1, the terminal voltage of a resistance R9 for feedback, and the load voltages taken out from a resistor R20 and a potentiometer RV2 are added by an adder consisting of resistors R21-R23, after which they are applied to the noninversion input of the amplifier A. The reference value and the variable gain are varied respectively by the potentiometers RV1, RV2. The impedance between the noninversion input of the amplifier A and the reference potential is varied by the straps between strap terminals t21-t22 and t24. With such circuit constitution, a conversion gain variable range and a reference value variable range are made always in a constant relation and are set simultaneously.
