Depending on the needed temperature measurement range
and associated accuracy, we suggest two methods to access to
the NTC resistance values.
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 Sat temperature T in K
NTC resistance in Sat rated temperature in K
Temperature in K
B value,material-specific constant of the NTC thermistor
Base of natural logarithm (e =2.71828)
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.
