How to Select and Design the Best RTD Temperature Sensing System
Designing a resistance temperature detector (RTD)-based temperature measurement system is a challenging, multistep process. It requires making choices in terms of the different sensor configurations, ADC selection, and optimizations, and how those decisions impact overall system performance. This paper discusses:
- Why RTD Temperature Measurement Is Important
- Main Temperature Measurement Challenges
- RTD Selection Guide
- RTD Configuration Circuit
- RTD System Optimization
- Selection of Excitation Current, Gain, and External Components
- RTD System Evaluation
