What is the temperature of the thermistor?
Thermistors are highly accurate (ranging from ± 0.05°C to ± 1.5°C), but only over a limited temperature range that is within about 50°C of a base temperature. The working temperature range for most thermistors is between 0°C and 100°C.
How does a thermistor change with temperature?
The thermistor Their resistance decreases as the temperature increases. At low temperatures, the resistance of a thermistor is high, and little current can flow through them. At high temperatures, the resistance of a thermistor is low, and more current can flow through them.
Is thermistor sensitive to temperature?
Thermistors Thermistors are temperature sensitive semiconductors that exhibit a large change in resistance over a relatively small range of temperature. There are two main types of thermistors, positive temperature coefficient (PTC) and negative temperature coefficient (NTC).
What is the difference between thermistor and thermostat?
In general, a thermostat is a cruder device than a thermistor. A thermostat only permits the metals to rise above or press upon a contact as temperature changes. A thermistor is more complex because it can read changes in conductivity and, thus, can express minute changes in temperature as conductivity changes.
What is the effect of temperature on the resistance of thermistor?
When temperature increases, the resistance increases, and when temperature decreases, resistance decreases. This type of thermistor is generally used as a fuse. Typically, a thermistor achieves high precision within a limited temperature range of about 50ºC around the target temperature.
What is thermistor and its working?
A thermistor is a resistance thermometer, or a resistor whose resistance is dependent on temperature. The term is a combination of “thermal” and “resistor”. A PTC thermistor works a little differently. When temperature increases, the resistance increases, and when temperature decreases, resistance decreases.
