Abstract

PURPOSE: To carry out the determination of high accuracy by feeding a predetermined voltage to both feed terminals of the bridge circuit having semiconductor pressure sensitive element alternately and synthesizing the both end voltages of the both resistances of the pressure sensitive element.
CONSTITUTION: At the two sides of the bridge circuit 11, the resistances R1, R2 which are the diffusion resistances of the diffusion-type semiconductor pressure sensitive element are provided, and onto the substrate for forming the diffusion resistance, inverse bias voltage A is applied. In the semiconductor-type voltage transmission device of the above construction, a predetermined voltage B is impressed alternately onto both the feed terminals (a), (b) of the bridge circuit 11 from the voltage adjusting portion 12 based upon the sampling pulse from the pulse oscillating portion 10. The voltage appearing between the both ends of both resistances R1, R2 respectively is synthesized and the obtained resistance is outputted to the operation amplifiers 16, 17, thereby the pressure determination signal of high accuracy being able to be obtained.
