Visual Distance Measurement on Hot Surfaces

for measuring distances, detecting positions, controlling filling levels and detecting geometric profiles on hot surfaces up to 1,500 °C.

These very harsh environmental conditions require specially configured technology and instrumentation of the measuring systems, for example protective housings and cooling frames.
