The particularly robust body, manufactured from corrosion-resistant stainless steel (alloy 1.4571 \/ 316Ti)<\/strong>, ensures reliable performance under permanent high-pressure and temperature loads.<\/p>\n

Upon request, versions in even more resistant materials<\/strong> are available, such as nickel-based alloys<\/strong> or Hastelloy\u00ae<\/strong>, allowing for the safe use of the indicator even in highly aggressive<\/strong> environments or those subject to high thermal stress<\/strong>.<\/p>\n<\/div>\n

The Type 522<\/strong> is distinguished by two opposing observation windows<\/strong>, made of thermally tempered borosilicate glass<\/strong> according to DIN 7080<\/strong>.
These windows allow for clear and safe observation<\/strong> of the process from both sides, as well as directional lighting of the medium<\/strong>.<\/p>\n

Bilateral visibility<\/strong> offers real-time visual control<\/strong> \u2013 a significant advantage in terms of safety and efficiency<\/strong> in modern process engineering.<\/p>\n

Threaded connections<\/strong><\/h5>\n

Internal threaded connections are available according to:<\/p>\n

    \n
  • DIN EN ISO 228-1 (BSP thread)<\/strong>, or<\/li>\n
  • ANSI B 1.20.1 (NPT thread)<\/strong><\/li>\n<\/ul>\n

    These standards ensure standardized and secure integration<\/strong> into existing piping systems.<\/p>\n
