The 335 model is constructed from high-quality 1.4571 (316Ti) stainless steel, which is highly valued by our customers. Like most of our displays, the 335 model is also available in a variety of other materials upon request.
The equipment is sealed using flat gaskets tailored to your requirements, sourced from a wide range of materials. This includes not only standard fibre gaskets, but also more specialised materials such as PTFE (Teflon®), NBR, novaphit® MST-XP, KlingerSil® C4400 and many other recognised brands.
For dark liquids or unlit tanks, the use of a reflective sight glass in accordance with DIN 7081 or similar is recommended. Due to the refraction of light in the built-in prisms, the liquid level can be more easily identified. However, if the tank is lit or if the colour of the product is visible, a transparent sight glass should be used. Reflective glass must not be covered with mica discs, as this prevents reflection.
If the maximum operating temperature of DIN 7081 borosilicate glass does not meet your requirements, or if the process conditions pose a problem even for this highly resistant glass, a specially adapted mica protective disc offers additional protection against temperature and steam. FEP or Halar® coatings provide additional protection for the borosilicate glass against aggressive chemicals.
