Fig. 4-16 Example of a sensor characteristic for continuous temperature detection
C1190/0 Evaluation of the Lenze standard motor temperature sensor
C1190/1 Evaluation of an application-specific temperature sensor. The operating point is in the almost
linear range (a) of the sensor characteristic. The operating range is determined by two vertices.
Between these vertices an interpolation takes place.
C1191/1 (100 °C)
C1191/2 (150 °C)
Definition of the temperature interpolation points which are assigned to the resistances of the
sensor.
C1192/1 (1670 Ω)
C1192/2 (2225 Ω)
