Understanding 4–20 mA Process Value Calculation made simple! In industrial automation, converting a 4–20 mA signal into the actual process value is one of the most important concepts for every instrumentation engineer. Learn how to calculate: • Span • LRV & URV • Process Value (PV) • Percentage of range This simple example helps you understand how field transmitters convert real process measurements into standard current signals used in PLC/DCS systems. Perfect for students, technicians, and automation engineers. Post navigation Why do we measure pressure in BAR, PSI, Pa & mmWC? 4–20 mA Calculation Explained Simply!
