NTC Thermistor Overview in 60 Seconds In this overview of NTC thermistors, Ametherm look at the different kinds and application uses for temperature sensing and how NTC thermistors accurately measure and compensate for temperature. This video will start by looking at the different types of NTC thermistors, such as probe assembly thermistors, disc and chip thermistors, and customizable thermistors. The different thermistor attributes will be examined, including voltage/current and resistance versus temperature. | |
5 Thermistor Sensor Considerations When Selecting A short video to help with selecting the right NTC thermistor. | |
ACCU-CURVE™ Precision Interchangeable Thermistors ACCU-CURVE™ precision thermistors offer interchangeability over a broad temperature range and eliminate the need to individually calibrate or provide circuit compensation for part variability. These NTC thermistors are used in many applications that require a high degree of accuracy and reliability. They commonly perform temperature sensing, control, and compensation for medical, industrial, and automotive applications. Interchangeable ACCU-CURVE NTC thermistors are usually selected when a high degree of measurement accuracy is required over a wide temperature range. |
