Longitudinal sight glass fitting type 330 PN 16/40For welding in or on Type USAGE Observation of the liquid level inside closed containers (kettles, tanks, silos, etc.). Type 330 sight glass fittings are rectangular longitudinal sight glass fittings for welding in or on, completed with a sight glass plate inserted and tightly screwed between the seals. After welding the base frame, it must be checked whether the sealing surface has distorted. If necessary, reworking is required! Also, pay attention to the specified torque values for the bolting according to the operating and maintenance manual! The working pressure does not apply to the base frame; this must be checked together with the pressure device according to AD2000 Leaflet B9! For clear media, dark or unlit containers, or a closed level indicator, it is advisable to use a reflex sight glass (see adjacent image). The refraction of light in the integrated prisms can make the level more distinguishable. However, if the container is illuminated, the medium is very clear, or if the color of the medium should be visible, a transparent glass should be used. Reflective glass cannot be protected with mica discs, as this prevents reflection. We are happy to assist you in selecting the suitable version 1) depending on ambient variables. 10112025 - Subject to technical changes and errors!

Longitudinal sight glass fitting type 330 PN 16/40For welding in or on BL [mm] The operating pressure of 40 barg is only achievable with transparent glasses, with liquid media, without significant technical glass impact. For transparent and reflective glasses subjected to steam or aggressive media, the maximum operating pressure PS = 35 barg at a maximum of 243 °C Our information sheet DIN 7081 provides more detailed information.
