How hot can a thermistor get?
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.
What is NTC temperature?
NTC is an acronym for Negative Temperature Coefficient. TE Connectivity (TE) is a leading designer and manufacturer of high precision discrete NTC thermistors, probes, and assemblies. An NTC thermistor is a temperature sensor that uses the resistance properties of ceramic/metal composites to measure the temperature.
How is NTC temperature calculated?
Take the reciprocal of the result to get the temperature in Kelvin. For example, assume a thermistor voltage divider circuit is connected to a 10 bit ADC. The beta constant for the thermistor is 3380, the thermistor resistance (R0) at 25°C is 10K ohms, and the ADC returns a value 366.
What should be the highest temperature up to which thermistor is heated?
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 the difference between a thermistor and a 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 a 10k NTC thermistor?
This is a type of resistor whose resistance varies with change in temperature. These NTC thermistors are made up from the combination of metal oxides which passed through sintering process which gives negative electrical resistance versus temperature (R/T) relationship to it.
How does a 10K thermistor work?
The enclosed negative temperature coefficient (NTC) thermistor, p/n 1600-10K, works by translating temperature into resistance, with resistance decreasing as temperature increases (hence the ‘negative coefficient’). As can be seen be the graph, the resistance of the thermistor drops very quickly.
What is the main function of a thermistor?
Thermistors are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body temperature.
