Configure Oil, Gas, and Petroleum Multi-Sensors with a Delta-Sigma ADC


The solution to high-precision multi-sensor electronics lies with the high-resolution analog-to-digital converter (ADC). The thermocouple, RTD, pressure sensors, and high-speed multi-channel delta-sigma (ΔΣ) ADC combination creates a high-precision, robust, multi-sensor system for oil, gas, and petroleum electronics. This design solution introduces issues associated with achieving a precise temperature and pressure cell interface with a ΔΣ ADC. The application circuit uses a pressure, thermocouple, and RTC sensor to achieve a single-device comprehensive conversion.
