Practical Application of NTC Thermistors in Daily Life

A thermistor is a device that gives many products the ability to regulate temperature. The devices sense temperature changes and how that affects resistance. By using a small, measured direct current that passes through the thermistor a user can accurately determine the drop of voltage as a result of temperature changes. Thermistors are usually constructed with sintered ceramics (these ceramics are rather sensitive to temperature). A thermistor gets its name from combining both thermal and resistor.

A thermistor is drastically important for many everyday functions, but not all thermistors are made the same way. A NTC Thermistor (negative temperature coefficient thermistor) is non-linear, which means that this thermistor has different resistance characteristics (as the temperature increases the NTC thermistor will decrease resistance). Not only is a NTC thermistor used for temperature, but it is also used to help with time delay or surges and sequential switching. The versatility of these devices makes them highly desirable for many different products and industries.

There is a great deal of practical application for NTC Thermistors, and this is partially because of their ability to accurately measure temperature and alter resistance. They are used in order to measure temperature, compensation, and control.

It is common to find NTC thermistor probes being used by the automotive and transportation industry. They are even used rather frequently by the United States Military. They create process and emission controls, as well as, differential temperature controls. A tire manufacturing company would use a NTC thermistor specifically to help cure tires. They will use the same thermistors to monitor engine temperatures. You can even find thermistors in missiles and rockets.

A good deal of people has NTC thermistors in one or multiple devices in their home. Two of the most common household items that have thermistors are burglar alarms and fire detectors. They are in your ovens and air conditioners as well.

Other places you are likely to find NTC thermistors:

There are different types of thermistors, and it is important to use ones that are designed to satisfy a very specific function. A professional thermistor company will be able to fully explain the difference between NTC and RTD thermistors. They will also help to ensure that you are getting the perfect thermistor for your specific/unique job.
