Inline sight glasses
A shock-proof glass cylinder is fitted between two flanges with a seal, and held by stud bolts. The stud bolts have a stop, which ensures a defined pre-tension between the seal and the glass cylinder. Plastic safety screens fulfil the requirement for optimal vision and protection against glass splinters. Alternatively, the proven metal screen can be used as splinter protection.
Sight glasses
A tempered glass pane is screwed to a male part with a welded end using two seals and a grooved nut. The glass is made of borosilicate, which offers excellent strength and thermal stability.
Sight glass fittings
The AWH sight glass fitting - DIN – SS is intended for installation in pipelines. It was designed and built for visual control of the flow of fluid in the food, chemical and pharmaceutical industries and for low-germ processes. Suitable flow media include water, steam, food, liquids from the chemical and pharmaceutical industry subject to a hygienic standard.
Sight glasses with wipers
Sight glasses with wipers are used for liquids with high solid content, which tend to form deposits. A manually rotated wiper reliably removes the deposits from the inside of the glass.
Lights for sight glasses
The light for the sight glass comes in two different versions:
1.For the DIN-SS sight glass which lights through the medium and
2.For the DIN welding sight glass which illuminates the medium.

The lights are suitable for illuminating sealed vessels like boilers, tanks, bunkers, silos and agitators and for visual flow control in pipelines.

When properly installed, a protective rating of IP65 in compliance with EN 60 529 / DIN VDE 0470 Part 1 (dust-tight and water-jet proof).
