Which thermistor should I use?
Thermistors are ideal when measuring a single point temperature that is within 50°C of ambient. If the temperatures are excessively high or low, a thermistor will not work. While there are exceptions, most thermistors work best in the range between -55°C and +114°C.
What is thermistor and its uses?
Thermistors are used as temperature sensors. They can be found in every day appliances such as fire alarms, ovens and refrigerators. They are also used in digital thermometers and in many automotive applications to measure temperature.
What does a NTC thermistor do?
NTC thermistors are used in the Food Handling and Processing industry, especially for food storage systems and food preparation. Maintaining the correct temperature is critical to prevent food borne illness. NTC thermistors are used throughout the Consumer Appliance industry for measuring temperature.
What is the b value of the NTC thermistor?
That is B T1/T2 or B 25/100 with typical NTC thermistor B values given anywhere between about 3000 and about 5000 . Note however, that both the temperature points of T1 and T2 are calculated in the temperature units of Kelvin where 0 0C = 273.15 Kelvin. Oct 4 2019
What can NTC thermistors be used for?
NTC thermistors are used as ICLs (inrush current limiters) to protect circuits of electrical and electronic devices against inrush currents easily and effectively. NTC thermistors are temperature-dependent resistors that employ special semiconductor ceramics with a negative temperature coefficient (NTC).
How does the NTC thermistor vary with temperature?
NTC (Negative Temperature Coefficient) thermistor has a characteristic of non-linear inverse varying resistance with respect to the temperature change. That is the resistance value decreases if the temperature of the thermistor is increased and it increases if the temperature is decreased.
