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.

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.

Designing with Delta-Sigma ADCs: System design considerations to optimize performance

Delta-sigma analog-to-digital converters (ADCs) are oversampling converters typically used in applications requiring higher resolution. However, ADCs do not work by themselves. In fact, they require several key components around them, including a front-end amplifier, a voltage reference, a clock source, power supplies, and a good layout. Many devices integrate these features together with the ADC to offer a complete system solution, which simplifies the design for customers and minimizes board space.
