Measurement Computing has released the white paper Data Acquisition Fundamentals: Making Accurate Temperature Measurements with Thermocouples, Thermistors and RTD Sensors.
When engineers and scientists need to make accurate temperature measurements for their particular applications, they should have as much information as much as possible about the benefits and challenges to each option available to them. This white paper explores the theories, operation and inherent pitfalls of the three most widely-used temperature transducers: thermocouples, thermistors and RTDs.
The white paper covers topics including:
- Temperature transducer advantages and disadvantages
- Transducer theory of operation
- Thermocouple cold-junction compensation (CJC)
- 2, 3, and 4-wire RTD configurations
- Thermistor linearization
The white paper is now available as a free download from the Measurement Computing website:
