Definition. When does inline measurement pay off — and when is the lab enough?
Offline measurement (oven, Karl-Fischer, pyknometer) gives high-precision samples — but only every 30–60 minutes with 1–3 hours latency. Too slow for process control.
Inline measurement delivers continuous data (100 Hz sample rate) directly from the line. Enables zero-delay control of dryer or press pressure.
Best practice: Inline measurement as control variable, offline sampling once per shift for calibration check.
FAQ
When does inline fully replace the lab? +
Practically never — inline values must be calibrated against offline references once per quarter, otherwise drift occurs.
Practical tip

Three data points — material, temperature, position — are enough for a first sensor recommendation.
