Smart Sensors in 4 to 20 mA Control Loops



by Publitek European Editors:

This article looks at the integration of sensors into 4 to 20 mA control loops and field bus implementations in industrial automation applications. Adding intelligence to the sensor allows more control and options for closed or open control loops with tighter latencies, and the article looks at the different approaches to implementing a smart sensor control loop. It looks at devices that are optimized for the control loops such as the Texas Instruments XTR117 transceiver and the HCPL-4200 optocoupler from Avago Technologies, as well as controllers that are optimized for sensors on these control loops such as the ADuC816 from Analog Devices.
