KILNSCAN 23 Line Scanner for Rotary Kiln Shell Temperature Monitoring K 2

KILNSCAN 23 Generalities Why a line scanner? Because, as long as the object being looked at is travelling, it procures: • An uninterrupted temperature profile (as opposed to pyrometers) • A temperature reading not subjected to unequal calibration of different instruments • A high resolution (up to 1250 points over 90° angle) & a large field of view • a high frame rate (up to 500 Hz) K 3
