ABSTRACT:
In the case of sensors having a characteristic for which the offset in the quiescent condition has a first temperature coefficient and the slope of the characteristic has a second temperature coefficient, while the quotient of the offset and slope coefficients is approximately constant, a point can be determined in which the characteristics for different temperatures (T) intercept. A temperature corrected measurement value can be determined, preferably with a microcomputer, from the sensor signal, the coordinates of the above-described intersection point, the sensor temperature and the temperature coefficient either of the offset or of the slope.
