Specify if you want enter the temperatures in Fahrenheit or Celsius. Also, specify if the
resistances used are in kOhm or Ohm and if circuit A (sensor grounded) or B (sensor at 5V) is
used.
The calculations assume the circuit (A or B) is run from 5V.
Enter the desired measurement temperature range. The range must be at least 50 degC or 90
degF.
Also enter the three measurement points from the calibration procedure as described above.
If you are making your own circuit, you can have Thermistorcalc calculate the optimum load
resistor. The temperature where this circuit has its maximum sensitivity is when the resistance of
the sensor and the load resistor are equal. Thermistorcalc calculates the sensor resistance at the
mid-point of the specified range and outputs the closest standard resistor value to that.
Do not make the load resistor smaller than about 1/5
th
of the thermistor resistance at
room temperature.
Once all fields are filled out, click on the ‘Create Table’ button. Thermistorcalc will generate the
correct lookup.
