Blanson Sight Glasses
Sight Glasses are designed for sanitary applications used in the food, dairy, and pharmaceutical industries. These units are used to provide 360-degree viewing of material flow in a line.
A sight glass is a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.
A Sight glass was first incorporated on a locomotive back in 1829 by John Rastrick at his Stourbridge works.
Modern sight glass is more structurally sophisticated than a water gauge. They are also known as sight windows, or sight ports. Modern sight glass usually is a glass disk held between two metal frames, which are secured by bolts and gaskets.
The strongest sight glasses are made with borosilicate glass, because of the greater difference in its coefficient of expansion.
Here at Blanson, we produce and deliver a complete range of sight glasses for all applications, processes and environments. They come in a wide range of styles, shapes and sizes.
