instrument

Instrumentation is critical for monitoring and controlling chemical processes. This category breaks down the basics of sensors, transmitters, control valves, and interlocks used in DCS (Distributed Control Systems) and PLCs (Programmable Logic Controllers). Topics include signal types (4–20 mA, HART, Modbus), calibration principles, control loop tuning, and typical instrumentation diagrams (P&IDs). Engineers can learn how to read tags, understand safety interlocks, and participate in loop checks or commissioning. Even for those not specializing in instrumentation, this knowledge helps bridge communication gaps between design, operations, and automation teams.
