TEMPERATURE SENSOR
• Typical temperature output
Depending on the needed temperature measurement range and associated accuracy, we suggest two methods to access to
the NTC resistance values.

e Base of natural logarithm (e=2.71828)
c The exponential relation only roughly describes the actual characteristic of an NTC thermistor can, however, as the
material parameter β in reality also depend on temperature. So this approach is suitable for describing a restricted range
around the rated temperature or resistance with sufficient accuracy.
d For practical applications, a more precise description of the real R/T curve may be required. Either more complicated
approaches (e.g. the Steinhart-Hart equation) are used or the resistance/temperature relation as given in tabulation form.
The below table has been experimentally determined with utmost accuracy for temperature increments of 1 degree.
Actual values may also be influenced by inherent self-heating properties of NTCs. Please refer to MEAS-France Application
Note HPC106 “Low power NTC measurement”.
