shrtrnd,
thank you, i know thermistors are not linear, i have a range of 20-70, i need to design a circuit, connecting ther thermistor to some component i dnt know now, to make my lnR vs 1/T(kelvin) graph linear.
what i really want to know is how to go about designing this circuit.
i willl be very grateful if u can show me how to design this circuit.. or model....
i know abt the K-type thermocouple, but i need to design it myself. thank you
Thermistor types are typically chosen for their relative 'linearity', WITHIN a specific temperature range.
You need to know the temperature range you're looking at, and how accurate you
want the circuit to be.
Thermistors are not linear. They are chosen for their relative linearity within the characteristic
curve of it's (operating) range
