Process Control & Instrument Calibration

What Will You Learn?

• Explain how a closed process-control loop works and identify the sensor, transmitter, controller, and final control element.
• Wire, read, and troubleshoot a 4-20 mA current loop and interpret instrument loop diagrams and P&ID symbols.
• Describe and select instruments for measuring pressure, temperature, level, and flow and state their working principles.
• Calibrate pressure, temperature, level, and flow transmitters using zero/span/linearity adjustment, five-point as-found/as-left tests, and HART trims, with full traceable documentation.
• Tune a PID controller and stroke, position, and document a control valve as the final control element.

Requirements

• Completion of relevant lower-level electrical, electronics, or mechatronics courses, or equivalent technical experience.
• Basic understanding of electrical circuits, Ohm's law, sensors, and workshop safety.
• Familiarity with using a digital multimeter and basic hand tools.
• Access to a process calibrator or loop calibrator (e.g. Fluke 754/789), sample transmitters, and a control valve or simulator for the practical exercises.
