Longitudinal sight glass fitting type 330 PN 16/40 For welding in or on

The ACI sight glass of type 330 is used for reliable observation of the liquid level in closed containers such as boilers, tanks, or silos. It is a rectangular vertical sight glass that can be either welded into the container wall or attached by welding.

The fitting is equipped with a sight glass plate made of high-quality borosilicate glass according to DIN 7081 (or comparable). This is securely framed between gaskets and tightly screwed to ensure permanent sealing and high pressure resistance.

Standardly, the sight glass type 330 is made of stainless steel 1.4571 (316Ti) – a material characterized by high corrosion resistance and durability. Upon request, the design is also available in many other materials, suitable for specific requirements and applications.

The sealing of the fitting is done with flat gaskets tailored to your needs from an extensive range of materials. In addition to the common fiber material gaskets, more sophisticated materials such as PTFE (Teflon®), NBR, novaphit® MST-XP, KlingerSil® C4400, and many other branded gaskets are also available.

If the maximum operating temperature of borosilicate glass according to DIN 7081 does not meet your requirements, or if the process conditions pose a problem even for the highly resistant borosilicate glass, a mica protection disc specially adapted for the fitting provides additional protection against temperature and steam. FEP or Halar® coatings also additionally protect the borosilicate glass from aggressive chemicals or alkaline solutions.

For applications in poorly lit containers, the use of a reflex sight glass according to DIN 7081 (or comparable) is recommended. These glasses are embedded with special prism structures that break and reflect the incoming light – thus, the filling level can be recognized much better.

If, however, the container is well-lit, the medium is very clear, or if the color of the medium should remain visible, a transparent sight glass is the better choice. It allows for an unaltered view and precise optical control of the contents.

Important note: Reflex sight glasses cannot be combined with mica discs and coatings, as the protective mica layer prevents the light refraction necessary for reflection. Transparent glasses, on the other hand, can easily be equipped with mica discs, FEP, or Halar® coatings, which is particularly recommended for protection of the glass in the case of aggressive media or high temperatures.

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.

Screws Cover frame Glass cushion Sight glass Gasket Base frame The ACI Flow sight glass type 334 is a lightweight design that offers a significantly enlarged viewing window compared to our type 330 at a relatively low working pressure of up to 3 barg. This construction allows the type 334 to combine the functions of our round sight glasses, such as type 318, and our level indicators for tank wall mounting Type 330. The fitting is equipped with a sight glass plate made of high-quality borosilicate glass similar to DIN 7081 (or according to customer specifications). It is securely inserted between seals and tightly screwed to ensure long-term tightness and high pressure resistance. Standardly, the Flow sight glass type 334 is made from stainless steel 1.4571 (316Ti) – a material characterized by high corrosion resistance and durability. Upon request, the version is also available in many other materials, tailored to specific requirements and applications. The sealing of the fitting is done with flat seals tailored to your needs from an extensive range of materials. This offers, in addition to the common fiber seals, more advanced materials such as PTFE (Teflon®), NBR, novaphit® MST-XP, KlingerSil® C4400, and many other branded seals. If the maximum operating temperature of borosilicate glass DIN 7081 does not meet your requirements, or if process conditions pose a problem even for the highly resistant borosilicate glass, a mica protection disc specially adapted for the fitting provides additional protection against temperature and steam. FEP or Halar® coatings provide additional protection for borosilicate glass against aggressive chemicals or alkalis.
