thermistor beta model PUBLIC

Beta model of a ntc thermistor.

Includes the effect of self heating.

Beta model of a ntc thermistor.

Includes the effect of self heating.

V1 is stepped from 0V to 10 V to allow the thermistor to start from the ambient temperature set by the TEMP parameter.

TEMP is stepped in the simulation over three temperatures.

Based on model in:

http://www.spectrum-soft.com/down/fall98.pdf

TEMP => ambient temperature in degC

TABS => Absolute zero in degC

TNOMC => the temperature at which RNOM is quoted in the thermistor datasheet

D1 => power dissipation value or factor quoted in the datasheet

B1 => the Beta coefficient for the thermistor from the datasheet

RNOM => nominal resistance of the thermistor at TNOMC

TAU => thermal time constant of thermistor given in datasheet
