This presentation addresses the topic of a various temperature sensing devices including RTDs, thermostats, thermocouples and thermistors. The advantages of each and the proper application will be covered.

Thermistors: What they are and how they work

  • March 2014
  • Number of views: 8995
  • Article rating: 4.0

Thermistors, derived from the term thermally sensitive resistors, are a very accurate and cost effective method for measuring temperature. Thermistors are usually two-terminal semiconductor devices made from semi-conductor materials that have an electrical resistance that varies non-linearly with temperature. Some materials provide better stability while others have higher resistance ranges and are fabricated into smaller thermistors. Each specificthermistor has its own unique resistance versus temperature characteristic.
