PT100/500/1000 Resistance Temperature Detectors (RTDs) are widely used in grid infrastructure and factory automation applications, where high precision temperature measurement is often required. Technical requirements include better than 20 mK accuracy of the Differential Temperature Measurement (DTM) for heat and cold meters from 0 to 180°C with temperature resolution better than 10 mK.
1Overview of temperature measurement in heat meters (2)
This section introduces the heat and cold meter training series.
2Measuring RTD sensors with delta-sigma ADS1220 family (3)
ADS1220 delta-sigma family uses the ratiometric approach for measuring RTD sensors with the built-in current excitation source.
3Differential Temperature Measurement (DTM) sub-system reference design (1)
TIDA-01526 implements a high-precision DTM sub-system using a 24-bit, low-power, Delta-Sigma ADC.
4Digital temperature sensor replacement of RTD sensors with TMP116 (1)
The TMP116 digital precision temperature sensor for the -55 to +125ºC range achieves higher accuracy than the Class AA PT sensor with a 1-point calibration.
