Inline color measurement during extrusion

When extruding solid to viscous masses, the materials must not be allowed to heat up too much. This would lead to burning and therefore undesirable coloration. The precise colorSENSOR CFO color sensors measure the color of the materials directly in the extruder. In the case of transparent materials such as gelatine, the measurement is carried out in transmission, while opaque materials such as plastic are measured using the reflection method. One or two special sensors CFS4-T150-P200 are installed directly in the extruder with either a transmission sensor CFS3-S-T250 or a reflection sensor CFS4-S-T250. The measurement takes place on the inside wall of the extruder, at up to < 200 bar pressure and < 250°C. The results are then used for process control.

Advantages:

Sensors directly in the extruder with 1/2"-20UNF fit
M12 Pressure-resistant up to < 200 bar and temperature-resistant up to < 250 °C
High reproducibility: ΔE < 0.5
