Note: transparent level gauge glasses are supplied in sets with gaskets or separately.
Reflex level gauge glasses offered by us are made by a recognized, global companies like Klinger, Maxos, Spectraglass of high-quality borosilicate ("extra hard") or aluminosilicate glasses. Glass in the production process is subjected to a polishing and toughening. This results in products characterized by high mechanical strength and high resistance to alkalis, acids and condensates. In the production process is conducted constant and precise control of transparency and the dimensions of manufactured glass.
Reflex gauge glasses are used to read the liquid level directly or with the use of CCTV (industrial television). In this type of glass on the chamber side (medium side) are imprinted longitudinal grooves (3 or 4), which walls are angled to each other at an angle of 90˚. Squeezing process causes the formation of grooves. On the surface of the grooves creates extremely smooth and hard glass layer, very resistant to the environment. With the grooving increases the angle of refraction which makes the visibility of the liquid level is much better than when using smooth glass. For reflective glass does not apply mica shields.
Reflex glasses may be used in pressure up to 35 bar. In this area are sufficiently resistant to the environment. The reading is clear and contrast. In the case of factors other than steam reflex glasses may be used up to 400 bar or 400˚C.
Depending on the width and thickness there are three basic types of transparent level gauge glasses:
- type A - width 30 mm, thickness 17 mm
- type B - width 34 mm, thickness 17 mm
- type H - width 34 mm, thickness 22 mm
In addition, the occasionally encountered also:
- Type C - width of 20 mm, thickness 12 mm
- Type D - width 25 mm, thickness 15 mm
Reflex level gauge glasses are supplied in sets with gaskets or separately.
