The Quality of a sight (gauge) glass depends mainly on the chemical composition and mechanical strength of the glass material. Analyses and acid/alkali tests constantly ensure a high glass-quality. The mechanical strength is reached by thermal prestressing. KLINGER gauge glasses are suitable for installation in liquid level gauges of almost any type.
The side facing the medium chamber is provided with moulded grooves set at 90° angles. The moulding process increases the resistance of the glass grooves to wear on tear. This makes it extremely resistant to boiler water.
Transparent glasses should always be chosen based on the type of contaminated, viscous or corrosive media. Within the given service limitations, they may be used for all media except steam at pressures up to 340 bar or temperatures up to 400 °C.
KLINGER reflex glasses are available in three different Types: A, B and H. For the specific overall dimensions and the application range, please refer to the product catalogue.
KLINGER transparent glasses are manufactured from “extra-hard” borosilicate glass. The surfaces on both sides are finely polished to ensure optimal transparency.
Up to 35 bar saturated steam, reflex glasses provide the optimum solution: they are corrosion resistant and provide a perfectly clear indication. Transparent glasses are preferably used with heavily polluted, viscous or acidic media at service conditions up to 340° bar or temperature up to 400 °C.
KLINGER transparent glasses are available in three different Types: A, B, H and TA-28. For the specific overall dimensions and the application range please refer to the product catalogue.
