Elements of a Thermistor

thermistorA thermistor is an electrical resistor whose resistance is greatly reduced by heating, and it is used for temperature measurement and control. Thermistor elements vary in both form factor and in their resistance versus temperature characteristics.

Precision thermistor elements are one type of element. These elements offer high stability and are available with 0.1 degrees Celsius and 0.2 degrees Celsius interchangeability.

These thermistors are finished and chemically stable. They are not usually affected by aging or exposure to strong fields of hard nuclear radiation. All of these thermistors are available as epoxy encapsulated and color-coded.

They offer excellent Linear thermistors consist of a thermistor composite for temperature sensing and an external resistor composite for linearizing.

Linear components are manufactured with different values for different temperature ranges. Depending on which networks they are connected to, they produce a varying voltage or resistance that is linear with temperature.

TA3 and TA4 are one more type of element of a thermistor. They come with a latch lock mechanism and are polarized by a mechanical key. They consist of three and four pin models and three and four wire RTD applications. These thermistors are well suited for most instrumentation uses. They feature both internal strain relief and external flexure relief.
