RTD to Voltage Reference Design Using Instrumentation Amplifier and Current Reference
Description
This reference design translates resistance temperature detectors (RTD) resistance to a voltage level convenient for an ADC input. A precision current reference provides excitation and an instrumentation amplifier scales the signal. The design also uses a three wire RTD configuration to minimize errors due to wiring resistance.
Features
- Converts RTD resistance to voltage 0 to 5V output across temperature range Eliminates lead resistance error Adjustable set with discrete resistors
Applications
- Analog input module
- Mixed module (AI
- AO
- DI
- DO)
- Expansion module
- Temperature controller
- Injection molding machine
