Process Instrumentation Signals: From Sensor to Control Room

About Course

This microlearning course looks more closely at how process instrumentation signals travel from a field sensor to the control room. Learners will explore the standard 4 to 20 milliamp signal, smart transmitters, and how signals are converted and processed at the control system. Designed for beginners, the course takes approximately 10-13 minutes to complete.

Explain the general concept of a 4 to 20 milliamp current loop signal
Explain why a current loop is generally preferred over a simple voltage signal for long field runs
Describe the general concept of a smart transmitter using HART
Explain what analog-to-digital conversion generally involves at the control system
Identify factors that support good signal integrity
Recognize why accurate signal transmission matters for process control and safety
