Instrumentation and Control Systems: The Clock Nobody Drew

Deep End Era. Engineering with Sankalp · Oct 10, 2026 · 56m

An oscillating loop is traced through the entire chain from physical measurement to a control decision. Field instruments, 4–20 mA signals, cabinets, actuators and control valves reveal how wiring and timing shape the result on a screen. The episode connects those foundations to safety, advanced process control and soft sensors. The central question is how to understand a plant as one interacting system rather than a collection of separate equipment lists.
