The ACI Type 323 circular product sight glass is a variation of the Type 321<\/a>, designed for a wider range of applications, particularly at high temperatures. It is intended for observing and illuminating the interior of sealed containers. <\/p>\n

PTFE seals, typically used in the Type 321 <\/a>sight glass, are no longer reliable at temperatures above 200 \u00b0C. To overcome this limitation, the Type 323 uses high-quality graphite composite gaskets, thereby increasing the temperature the sight glass can withstand to 280 \u00b0C, or up to 320 \u00b0C with a mica disc. <\/p>\n

Even at temperatures exceeding the limits specified in DIN 7080, type 323 can be used with non-tempered borosilicate glass up to 400 \u00b0C.<\/p>\n

If the process conditions pose a problem even for highly resistant borosilicate glass, a specially adapted mica or FEP protective screen for the connection provides additional protection against steam and aggressive chemicals, such as alkalis with a pH value of up to 14.<\/p>\n
