The TF56 is a precise dual channel, scattered light turbidity sensor. This sensor is designed to provide inline control solutions for a variety of industrial processes, from sanitary CIP/SIP applications to high-pressure, high-temperature industrial applications.

The TF56 uses light in the visible (VIS) and near infrared range (NIR) from 400 to 1100 nm. A precisely defined, constant light beam penetrates the process medium. Light scattered from particles (trace suspended solids, undissolved liquids or gas bubbles) in the medium is detected by four hermetically sealed silicon photo diodes at an angle of 11°.

The unscattered light is detected simultaneously as direct beam by a reference photo diode. This unique dual channel design compensates for disturbances such as background color or color changes of the carrier medium. The TF56 can be calibrated in ppm, EBC or FTU.

The special optical window is made from a single crystal sapphire. This provides superior resistance to all abrasive and corrosive media. The TF56 is available with a broad variety of line sizes, process connections and wetted materials and can be adapted easily to the process. High temperature and silicone free models are also available.
