Different Thermistors for Different Applications

When looking for the right thermistor to use for the right application, there are a few things that need to be considered. There are three key pieces that should be looked at in order to get the best results: the right base resistance; specify a resistance versus temperature relationship; and thermistor size or sensor package style.

Thermistor accuracy is the best around. They are one of the most accurate types of temperature sensors. However the level of accuracy will depend on the type of thermistor you get.

Getting a finished thermistor is important for stability. These types of thermistors are chemically stable and not significantly affected by aging.

Size or sensor package style is an important feature that needs to be looked at when deciding what thermistor will work best. The first step is to choose the right resistance and curve. When this is established, it’s best to determine how the thermistor will be used. It’s important to remember that a thermistor only measures its own temperature.

A general-purpose sensor design should be considered because they can be adapted to a wide variety of uses. Ranging from electronic equipment to structures, processes and design and reliability testing applications, the sensors are easy to install and monitor.

Liquid immersion measurement is another important feature to look into. Exposure to liquids needs to be monitored. Thermistors need to be protected from corrosion as well as positioned into the fluid so it will come to the needed temperature. Care must be taken to make sure that there is a good thermal path to the thermistor.
