Reflex

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.

Transparent level gauge glasses offered by us are made by a recognized, global companies like Klinger, Maxos, Spectraglass of high-quality borosilicate ("extra hard") or aluminosilicateglasses. Glass in the production process is subjected to a two-sided 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. Transparent (smooth) level gauge glasses  are used to read the liquid level directly or with the use of CCTV (industrial television). They can be (type TA 28) used up to 180 bar / 356°C for aggressive environments affecting (interacting) the glass (eg. saturated steam, hot water, alkalis) and up to 300 bar / 400°C for soft environments. Glass must be protected from the medium side through the mica shields. They are especially recommended for environments contaminated, viscous and highly corrosive. Depending on the width and thickness there are four 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 type TA 28 - width of 27.6 mm, 16.8 mm In addition, the occasionally encountered also: Type C - width of 20 mm, thickness 12 mm Type D - width 25 mm, thickness 15 mm Transparent level gauge glasses are  supplied in sets with gaskets and mica shields or separately. The set, packaged in a common box, consists of: box set of washers  gasket mica shield for the media side mica shield for the place of observation(with a hole Φ ca. 1 mm) installation guide   In all TA-28 sets, soft washers and protective washers are made from graphite foil. In set TA-28-I gasket is made from graphite laminate KlingerGraphite type SLS (see desc. here), but for sets TA-28-III .. TA-28-IX KlingerGraphite type PSM is used (see desc. here). In sets type A, B, H all washers are made from KlingerSil plate type C-4430 (see desc. here), but gaskets are made from graphite laminate KlingerGraphite type SLS (see desc. here).   It is good to know, that the role of the mica shield installed on the outside (ie, on the side of the viewer) is to reduce the thermal shock to which gauge glass is exposed, working on the one hand, in an environment of high temperature (steam, hot water), and on the other, with a low (room) temperature environment. Outer mica shield helps to a longer faultless operation of the set. The hole made in the shield, protects against moisture staying between the glass and mica while mounting assembly and relieves pressure above and below the shield during normal operation. box: set of elements: installation guide:   We offer transparent glass meet the following standards: ÖNORM M 7354 (Austrian standard) DIN 7081 (German standard) JIS B 8211 (Japanese standard) ÖMV-Spez.

The base flange of Type 330 is set into the wall of a container or pipe and is fixed all-round with a welding seam. The base flange has an indentation for glass and seals, which are held by a cover flange. Type 330 only needs a very low torque for the fixing screws, whilst still achieving very reliable sealing. Type 330, like most of our fittings, is available in a range of materials, including standard types of container steel such as S235, or standard stainless-steel alloys such as 1.4571 or 1.4404, but high-performance materials such as Hastelloy or duplex alloys are available on request. For the sealing, we use tried and tested high-quality flat seals from well-known manufacturers such as KlingerSIL C4400 or novaphit MST. It is also possible to supply pure PTFE seal plates and soft seals such as NBR or EPDM directly. The industry norm DIN 7081 includes the use of sight glasses of different lengths in the “Transparent” and “Reflex” versions. Transparent glass means simple, smooth glass plates. This type can, should the operating conditions require it, be fitted with protective layers made of mica or other materials such as KEL-F. We recommend the reflex type, if operating conditions allow it, for use with clear, colourless liquids. Due to the grooves contained in this type, the meniscus in the liquid phase can be seen clearer than with the transparent variety. Read on for technical data and detailed views.
