NTC thermistors are widely known to have almost endless applications. These sensors measure temperature and liquid levels in many different industries and devices. For instance, you can almost always find NTC thermistors in automotive electronics, medical equipment, and green technology.
In many cases, thermistor probes are used exclusively as a simple NTC thermistor chip encapsulated in glass or epoxy. In other instances, they can be potted inside of a plastic or metal housing (with 2 insulated leads).
Beyond industrial applications, NTC thermistors are found in the places we live and work. Considering their wide range of applications, it is necessary to understand exactly how these thermistor probes operate and exactly what capacity and performance output you need. Thermistors are designed and sold in different shapes, sizes, and encapsulation options.
All thermistors start as a small chip attached to 2 lead wires. Different housing and cover options need to be determined, along with the thermally conductive epoxy used to fill the remaining space. Probes are customed based on their application and working conditions' exact requirements. For instance, probes used in conjunction with lithium-ion batteries might require a ring lug for easy mounting to a battery terminal.
Choosing the right thermistor and housing is an extremely vital part of ensuring temperature sensing and resistance is accurate and constant.
