The Fundamentals of 4-20 mA Current Loops

This recorded webinar was designed as an introductory class for those who deal with process signals but are not electrical engineers. In the world of process control, there are a myriad of different types of process inputs. Analog signals, where information about the process is transmitted via varying amounts of voltage or current, are the predominant type of input in industries requiring process control today. Of all possible analog signals that can be used to transmit process information, the 4-20 mA loop is the dominant standard in the industry. Having a grasp on the history, workings, pros and cons of the 4-20 mA loop will help you to understand why it is the dominant standard for the industry and allow you to make informed decisions about your process control. KEY TAKEAWAYS: After watching this recorded webinar you will: have a strong understanding about the fundamentals of the 4-20mA current loop be better equipped to choose the correct devices and instruments for your installation understand when, where, or if a current loop solution is right for your application WHITE PAPER To view a white paper version of this webinar, please visit http://bit.ly/FND420WP RELATED ARTICLES Why a 0 mA Signal is Not Practical, visit https://bit.ly/0_MA Back to Basics: The Fundamentals of Loop-Powered Devices, visit https://bit.ly/FNDLPD Back to Basics: Loop vs Line Power, visit https://bit.ly/LPVLN ABOUT THE PRESENTER Precision Digital's 4-20 mA expert, Joe Ryan brings more than 15 years of process signal experience in the design, marketing, support, and manufacture of process measurement and control devices.
