The potentiometer rotary position sensors from Huiren Electronics

The positioning sensors camera-based system determines the current position based on a mounted bar code tape. This acts as a reference point against which the Huiren 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 potentiometer rotary position sensors 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.
