Abstract

PURPOSE:To compensate the influence of the fluctuation in source voltage and zero point temp. characteristics by operating the outputs of strain gage bridges with the outputs of circuits generating the outputs depending upon the source voltage and temp. CONSTITUTION:The outputs of strain gages SG1-SG4 are inputted via operational amplifiers OP1, OP2 to an operational amplifier OP3. The output of an operational amplifier OP3 of a voltage dependent output generating circuit connected with the diode D and resistance R11 generating the outputs depending upon temps. to resistance full bridges R6, R10, R12, R13 detecting the fluctations in source voltage is also inputted to the amplifier OP4, whereby the source voltage fluctuations and zero point temp. characteristics are compensated.
