Typical temperature output
Depending on the needed temperature measurement range
and associated accuracy, we suggest two methods to access to
the NTC resistance values.
1
The actual characteristic of an NTC thermistor can, however, only
be roughly described by the exponential relation,as the material
parame ter B in reality also depends on temperature. So this
approach is only suitable for describing a restricted range around
the rated temperature or resistance with sufficient accuracy.
NTC resistance in Ωat temperature T in K
NTC resistance in Ωat rated temperature in K
Temperature in K
B value,material-specific constant of the NTC thermistor
Base of natural logarithm (e =2.71828)
2 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 tabulated form. The below table
has been experimentally determined with utmost accuracy for
temperature increments of 1 degree.
