Module 1: Instrumentation Fundamentals & Calibration
Universal Foundation for Safety, Quality & Compliance
1. SI Units: The Language of Measurement
Core Concept: Standardised units ensure consistency across industries.Key Units:
Pressure: Pascal (Pa), bar, psi
Temperature: Kelvin (K), Celsius (°C), Fahrenheit (°F)
Flow: m³/s, L/min, GPM
Level: Meters (m), % of span
Industry Application:
Nuclear: Precise Kelvin for reactor cooling.
Oil & Gas: PSI/bar for pipeline pressure.
Power: °C/°F for turbine exhaust monitoring.

2. Accuracy, Precision & Errors
Definitions:
Accuracy: Closeness to the true value.
Precision: Repeatability of measurements.
Error: Deviation from true value (e.g., ±0.5% FS).
Industry Impact:
Safety: Inaccurate pressure readings ⇒ overpressure explosions.
Quality: Imprecise temperature control ⇒ product defects.
Diagram: Accuracy vs. PrecisionCaption: High accuracy + low precision = Consistent errors. High precision + low accuracy = Repeatable but wrong.
