Acceleration (VLM)

Description: The measuring device VLM records the surface velocity of the measuring object optically and contact-free from the distance. This takes place independently from its color, brightness or surface structure. Due to the measuring principle the device works slip-free and records high accelerations, too.
Applications: Velocity measurement, Length measurement (Tube inspection lines)

Color (CR)

Description: CROMLAVIEW color sensors are based on the three-range procedure and they process colors according to human perception. Color-sensitive filters, which emulate the tristimulus function of the human eye, facilitate the correct recognition of color values. In terms of color information, opaque solid objects can be evaluated in the epi-illumination method, transparent liquids in the transmitted light method and self-luminous objects in the active mode.
