2. What is an NTC 100k Thermistor?
An NTC 100k thermistor is a type of temperature sensor that relies on the principle of negative temperature coefficient (NTC). As the surrounding temperature changes, the resistance of the thermistor varies inversely. This characteristic makes it an ideal choice for precise temperature measurements in a wide range of environments.
3. How Does an NTC 100k Thermistor Work?
NTC 100k thermistors are made from a ceramic or polymer material with specific temperature-dependent properties. When subjected to changes in temperature, the molecular structure of the thermistor alters, resulting in a corresponding change in resistance. By measuring this resistance, we can accurately determine the temperature.
4. Advantages and Disadvantages of NTC 100k Thermistors
NTC 100k thermistors offer numerous advantages, including high sensitivity, compact size, and cost-effectiveness. They also exhibit excellent interchangeability and long-term stability. However, it’s important to consider factors like self-heating and limited temperature range when utilizing these devices.
