Abstract

An apparatus for detecting a temperature by means of at least one temmerature-responsive sensing resistor (F1,F2) comprise an evaluating circuit which processes a voltage drop depending on the temperature of the sensing resistor. The sensing resistor (F1,F2) lies at a common current source (1) in series with two fixed calibration resistors (G, D). The basic resistor (G) has a lower calibration value (Rel) which is assumed by the sensing resistor at a predetermined lower temperature. The differential resistor (D) has a differential calibration value (Rd) of such a size that the series circuit of the calibration resistors has an upper calibration value (Re2) which the sensing resistor assume at a predetermined higher temperature. The evaluating circuit determines the actual temperature from at least one measurement voltage drop (Vfl, Vf2) with regard to a characteristic calibration curve resulting from at least one calibration value (Rel, Re2, Rd) and the associated calibration voltage drop (Vel, Ve2, Vd). This leads to a very simply constructed apparatus which is easily adjustable. Fig. 1.
