Patent ID: 8443675

Claim:
A dual physical quantity sensor, comprising: a first physical quantity detecting element detecting a physical quantity of a first object to be measured; a second physical quantity detecting element detecting a physical quantity of a second object to be measured; a temperature detecting element detecting the temperature of the first physical quantity detecting element and the second physical quantity detecting element; a first correcting portion performing a correction that eliminates, from a detection signal from the first physical quantity detecting element, a fluctuation portion due to a change in temperature, to output a corrected signal as a measurement signal for the first object to be measured and; a second correcting portion performing a correction that eliminates, from a detection signal from the second physical quantity detecting element, a fluctuation portion due to a change in temperature, to output a corrected signal as a measurement signal for the second object to be measured; wherein: the temperature detecting element is integrated in mutual contact with the first physical quantity detecting element and the second physical quantity detecting element.
