Precision temperature measurement in heat and cold meters

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 either 20 mK precise Differential Temperature Measurement (DTM) for heat and cold meters from 0 to 180°C or better than 400 mK precision over the full range of -200 to 850°C for industrial sensor transmitters.

Overview of temperature measurement in heat meters

This section introduces the heat and cold meter training series. The series covers the basics of RTD sensors and their usage in heat and cold meters, as defined in the EN1434 set of standards.

Measuring RTD sensors with Delta-Sigma ADS1220 family

ADS1220 Delta-Sigma family uses the ratiometric approach for measuring RTD sensors with the built-in current excitation source. Offset and gain calibration are required before the resistance measurement is converted into a temperature reading by the application MCU.

Differential Temperature Measurement sub-system reference design

TIDA-01526 implements a high-precision Differential Temperature Measurement (DTM) subsystem using a 24-bit, low-power, Delta-Sigma ADC. Heat and cold meter DTM subsystems typically use two 2- or 4-wire RTDs such as PT100, PT500 or PT1000 and can achieve measurement accuracy of 20 mK over a water temperature range of 3°C to 180°C. The MSP430FR6047 application MCU converts the resistance value into a temperature reading in TIDA-01526.

Digital temperature sensor replacement of RTD sensors with TMP116

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. A small PCB including TI's TPD1E10B06 or TPD1E04U04 protection devices can be sealed into a RTD metal tube and meet the EN 61000-4-2 and -4-4 levels of ESD protection. The 64-bit internal EEPROM inside TMP116 stores user defined calibration data into the digital temperature sensor, simplifying integration with application MCUs, such as MSP430FR6047, FR6989 or CC13xx/26xx wireless MCU families.

Signal Acquisition system using TI’s High Resolution SAR Converters

The report illustrates a differentially driven signal fed into TI’s 20 bit SAR ADC. This results in raw data available for data processing. This has zero latency and high linearity.

This TI design illustrate the CW Doppler signal conditioning for an ultrasound machine. The input signal bandwidth up to 100KHz and 128 differential signals from AFEs are summed together in a differential high speed amplifier and digitized with TI SAR ADC.
