The Optec inline milk product concentration detector uses optical technology to measure whiteness in the process stream thus determining milk content. The measurement technique relies on a light emitting source projecting a light beam into the process stream. This causes scattering of the light to a sensitive light detector which provides a concentration-dependent signal.
The Sartorius Observer metal detector is equipped with specially designed sensors based on magnetic field measuring technology.
Recent developments in metal detection technology have made this quality-control process an increasingly important safeguard against contaminant food scares
