Contrast sensors for industrial process control
Our contrast sensors do not focus directly on the detection of colours, but on the detection of colour differences, i. e. contrasts. They are configured specially for an application and often allow to detect even small colour differences, which could not be distinguished with standard colour sensors.
Our FSP25D and FSP60D contrast sensors are also differential sensors: they don’t just detect colour contrasts, but also respond to rapid signal changes. This means that a switching process is only triggered in case of an abrupt colour change!
Contrast sensors for special applications
This sensor was specially developed for detection of adhesive tapes used for splicing paper webs at high speeds and varying working distances.
This sensor focuses on detection of rapid signal changes or colour changes over short distances.
Our tri²dent multi-wavelength sensor platform can also be used in the visible and ultraviolet wavelength range to detect visible or invisible colour contrasts.
