About Lab
Visualize how a 4–20 mA loop works using an interactive virtual lab. Understand signal flow and continuity without wiring or calculations..
The 4–20 mA Loop Flow Visualizer helps beginners understand how information flows through a current loop in industrial measurement systems. Instead of focusing on wiring diagrams or current values, this lab visually demonstrates loop continuity, signal flow, and communication between components. It builds clear intuition about how loops work and why continuity is critical.
How to Use This Lab
Observe the healthy loop with continuous flow.
Watch how signal flows through each component.
Introduce a loop break at a selected point.
Observe how flow stops across the loop.
Restore the loop and observe normal behavior.
