Resistance Temperature Detectors (RTDs) are standard sensors used across industrial applications to measure temperature. RTDs often use a platinum wire to measure temperature. This video introduces a reference design for replacing the platinum element with a digital temperature sensor to improve accuracy and overall system cost. Tune in as we review the current RTD implementations, the new digital replacement, and system-level performance testing.
