Ntc Thermistor Diagram. However some specially designed ntc thermistors are used at absolute zero temperature 273 15 o c and some can be used above 150 o c the figure below shows the characteristic curve of a ntc. Ntc 103 thermistor 10k ω.
R o nominal resistance resistance at temperature t 0 is 25 c or 298 15k. Thus changes to its resistance due to changes in temperature produces a temperature related output voltage. The potentiometer which can be of any value functions as a calibrator.
Ntc 103 thermistor 10k ω.
Ntc thermistors are the most commonly used especially the 10kω ntc thermistor and along with an addition series resistor r s can be used as part of a simple potential divider circuit. Voltage divider circuit is. Before we begin adjust the potentiometer so that the led is off when there is no heat applied to the thermistor and on when heat is applied to the thermistor. While most ntc thermistors are typically suitable for use within a temperature range between 55 c and 200 c where they give their most precise readings there are special families of ntc thermistors that can be used at temperatures approaching absolute zero 273 15 c as well as those specifically designed for use above 150 c.
