- TIDA-00189, Isolated Loop Powered thermocouple Transmitter Reference Design. 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
