Application Note About RTD Interfacing and Linearization Using an ADuC8XX MicroConverter

In the application note we can learn things about offset, errors, linearization techniques, gain, linearization, and measurement. Lots of explanation like equations, input voltage noise, range, mathematical method, and error are presented inside this application note.

This application note presents info about linearization functions, transfer function, temperature range, noise, and errors offset. These are excerpted from this application note:

The platinum RTD is one of the most accurate sensors available for measuring temperature within the range –200°C to +850°C, capable of achieving calibrated accuracy of ±0.02°C or better. To get the most of an RTD’s accuracy, however, requires precise signal condition ing, A/D conversion, linearization, and calibration. The Analog Devices MicroConverter product family (http: //www.analog.com/MicroConverter) includes devices with a 16-bit or 24-bit ADC and an 8052 MCU in a single chip along with signal conditioning circuitry ideally suited to RTD sensors. This application note describes ways to implement a complete RTD sensor interface using the ADuC834 (or other similar MicroConverter) and just a few passive components.

In addition, this application note contains information around resistance, calibration, linear, equation, and rtd transfer function.
