What are PTC thermistors made of?
Most PTC thermistors are made from doped polycrystalline ceramic (containing barium titanate (BaTiO3) and other compounds) which have the property that their resistance rises suddenly at a certain critical temperature. Barium titanate is ferroelectric and its dielectric constant varies with temperature.
Characteristic
high precision NTC thermistors
Small size, Fast response
Steady Operating for long time
Good quality of copherence and interchange
Scale production, high ratio of features to cost
This is a property of a Negative Temperature Coefficient resistor (NTC ).
There are also thermistors that have Positive Temperature Coefficient (PTC for short) which means as the temperature increases, the resistance increases. However, PTC thermistors have a sort of tipping point and greatly change the resistance at some temperature. This makes the PTC thermistor a little harder to interface with. For this reason, for most low-cost temperature measurement, NTC thermistors are preferred.
For the remainder of the article, you can assume we'll be referring to NTC type thermistors.
Knowing the temperature in a project can a very useful piece of data to have handy. Knowledge of temperature can help regulate room temperature for a comfortable environment, ensure that a 3D printer bed is hot enough for materials like ABS to stick to its surface, prevent engine overheating, and keep food from being burnt.
For this article, we are only concerned with one type of sensor that can measure temperature. This sensor is called a thermistor.
