Temperature Sensor Interface Module for Programmable Logic Controllers (PLC)
TIDA-00018: The TIDA-00018 reference design enables faster development of high precision temperature measurement solutions using 24-Bit delta-sigma ADC and most widely used temperature sensors like thermocouple and RTD. The design guide will address the sensor signal conditioning, thermocouple cold junction compensation, ratiometric measurement technique for RTD, recommended software flow, sensor linearization, sensor diagnostics, transient protection, PCB layout and other practical design considerations for achieving high precision robust design for temperature measurement in industrial applications. The Temperature Sensor Interface Module is a fully isolated design, which is essential for small sensor signal measurement. The heart of this reference design is a 24-Bit delta-sigma ADC that provides a high resolution, high integration, low noise, and low cost complete sensor analog front-end (AFE) for DC sensing applications. This ADC also makes it suitable to interface with different types of sensors, thus saving board space, reducing design efforts, decreasing the time to market, and lower BOM cost. Furthermore, external protection circuitry has been successfully tested for compliance with regulatory IEC61000-4 EFT, ESD, and surge standards. Compliance to IEC61000-4 is necessary to ensure that the design not only survives but also perform as intended in the harsh/noisy industrial environment.

Isolated Loop Powered Thermocouple Transmitter Reference Design
TIDA-00189: The Isolated Loop powered Thermocouple Transmitter reference design is a system solution providing precision K-type thermocouple measurements for 4 to 20-mA isolated current-loop applications. This design is intended as an evaluation module for users to fast prototype and develop end-products for process-control and factory-automation. Potential challenges with thermocouples as a temperature sensor include tiny voltage outputs, low sensitivity and nonlinearity; in addition, because in industrial environments ground potential differences higher than 100V are common, thermocouple and signal conditioning circuitry must be galvanically isolated. The design files include design considerations, block diagrams, schematics, Bill of Materials (BOM), layer plots, Altium files, Gerber Files, and MSP430 Firmware.
