Beta Value is an indication of the shape of the curve that represents the relationship between the resistance and the temperature of a particular Thermistor. Calculate the beta value to achieve the right characteristic at a given temperature vs the resistance for a specific application. it is a vital step in the component selection process.
It is the characteristic or the curve of NTC thermistor that best defines the resistance as a function of the temperature.
NTC thermistors beta calculation formula
4 key Components of NTC thermistor Beta Calculations
- RT1 = Resistance at Temperature 1
- RT2 = Resistance at Temperature 2
- T1 = Temperature 1 (K)
- T2 = Temperature 2 (K)
Most of AMWEI NTC thermistor Beta B value is calculated from measurements at 25C and 50C, or 25C and 85C,
that is expressed in B(25/50) , or B(25/85), or the other temperature point the user most concerned.
