Linear measurement sensors

New directions in linear measurement technology

Linear measurement sensors from SICK use highly innovative technologies for the non-contact measurement of positions, speeds, and lengths. The OLM sensors' camera-based system determines the current position based on a mounted bar code tape. This acts as a reference point against which the OLM sensor can position itself accurately, depending on variants, over a length of up to 10 km and as little as 0.15 mm, regardless of whether the product travel path is in a straight line or curved.

The sensors in the OLV product family determine lengths and speeds using the laser Doppler effect. This technology enables extremely precise measurements to be made of almost any material – at speeds of up to 80 m/s and material temperatures of up to 1,100°C.
