en - Installation
• Direct installation with threaded connection (A)
• Window of microwave-permeable glass or plastic (B & C), e.g. PTFE
• Installation with danger of condensation on the container's inner wall (C)
• Sight glass fittings (D) for various applications with microwave-permeable windows made of glass
• The maximum length E depends on the permittivity and the water absorption of the plastic material,
example PTFE: E ≤ 300 mm
• Fouling (material accumulation) in the nozzle area (F) should be avoided in a suitable manner, e.g. by purge air
• The pipe can be made of any desired metallic material, edges inside the pipe (e.g. at transitions) can cause signal attenuation
and thus should be avoided wherever possible (G). The length H of the pipe is unimportant due to the waveguide effect.
