3.1 Window Reflectance
In-line analysis of paste, granulates, slurry, powdered products and similar materials in pipes or fluid
transport systems can be performed without need for bypass streams. The sample material must pass
over the sample interface window.
The window reflection interface may easily be installed into the production line using standard GEA
Tuchenhagen flowcell mountings, or by welding an interface flange into the wall of the
pipe/transport system. GEA Tuchenhagen is well known for innovative, hygienic components for
operation in the process stream.
• Temperature: 150°C (302°F)
• Pressure: Vacuum > 1 Torr (approximately 1 mm Hg), Pressure < 3000 PSI
• Lens: Sapphire; diameter 45 mm (1.8”), thickness 12 mm (0.5”), with
EPDM O-ring seal for reliable, temperature resistant sealing
• Pipe flowcells: Fits directly into GEA Tuchenhagen Varinline Access units (DN40 to
DN150 with 68 mm [2.7”] opening). This mounting method facilitates
implementation of CIP (clean in place) and SIP (sterilize in place) methods.
• Transport System: Stainless steel welding flange
3.2 MicroBundle Fiber Optic Interface
Direct in-line measurement with microbundle fiber optic probe interface, optimized for process
streams of clear to opaque liquids, slurries, suspensions, and powders. The analyzer may be
configured with a reflectance or immersion probe based upon sample type.
316 Stainless Steel or Hastalloy Probes (custom materials also available)
• Micro Interactance Reflectance Probe
• Micro Interactance Immersion Probe
• Micro Interactance Reflectance with purge on collection tip
(requires clean air or nitrogen for purge)
• Optimized Micro Reflectance (45-degree) Probe with 3 meters of fiber
(Angled face for optimized sample collection)
