Field instrumentation and process control: 4-20 mA loops, HART protocol, hands-on calibration procedures, P&ID symbol reading, transmitter ranging (zero/span), control valve sizing, PID tuning, and Safety Instrumented Systems. Four levels from loop tech to process control lead.
20 Questions · Signals, P&IDs, safe work
4-20 mA current loops, 0-10 V signals, RTDs vs thermocouples, pressure and level basics, loop-powered vs 4-wire transmitters, reading P&ID symbols (instrument bubbles, ISA 5.1 tag codes, valve/actuator symbols), and safe field work.
20 Questions · HART, hands-on calibration, ranging
HART protocol deep-dive (multidrop, burst mode, device descriptors, HART 7 diagnostics), hands-on 5-point calibration procedures with documented steps, transmitter ranging and zero/span (URV/LRV, rerange vs recalibrate), as-found/as-left records, valve stroke checks, and traceable NIST test equipment.
20 Questions · PID tuning & valve sizing
PID structure, tuning methods (Ziegler-Nichols, lambda), control valve sizing basics (Cv calculation, choked flow, rangeability), valve characteristics (linear/equal-percentage/quick-open), cascade and ratio control, and loop troubleshooting.
20 Questions · SIS, advanced control, ISA-84
Safety Instrumented Systems (SIS) and SIL, ISA-84 / IEC 61511, model-predictive control (MPC), analyzer systems, alarm management (ISA-18.2), and LOPA.
