Four Considerations for the Perfect Thermistor

A thermistor is a device that helps to sense temperature. It is made up of semiconductor materials, which have been sintered so they may show changes in resistance that is related to temperature. Thermistors boast an extremely accurate and consistent way to monitor temperature.

When looking for the perfect thermistor you want to look for 4 main qualities. First, the device should not have an effect on what it is measuring. This means that the thermistor only reads and does not influence or change temperatures. You also need your device to be completely and reliably accurate. A thermistor should have a quick response time, and has outputs that are easily accessible. Wanting these 4 qualities is important, but you must understand that different types of thermistors work in different ways. Considering this is the case, you will need to do some exploring to find out the device that will work best for you and what you are attempting to do.

For instance, if you don't want your thermistor to influence temperature than you must consider the size of the sensor, how it's encapsulated, and also its lead configuration measurements. Choosing the appropriate sensing device will allow you to mitigate potential stem-effects and measurement errors.


When you begin to think about the accuracy of your measurements you will consider options for sensors. Understand however, that picking the appropriate sensor is a literal waste of time if you haven't first considered stem-effect.

The time it takes for a device to respond is directly dependent on the size of your sensor; however, leads can also sometimes influence response. Micro-bead technology offers for the quickest response time to date, but micro-beads is not perfect for every situation.

There are different sensors that have different temperature range, accuracy, long-term stability, output and more. It is a difficult task to navigate these decisions on your own. This is mainly the case because of the substantial amounts of options you have. If you want a device that meets all the four big standards, you will have to fully understand what it is your trying to do (the ins and outs), as well as picking the right materials, sizes, and configurations. Sensor Scientific will help you through this journey.

A properly functioning thermistor can help to make business possible, where as a weak or malfunctioning one can stop work in its tracks. Be smart and shop right.
