Product Description

Safety Double-Layer Sight Glass 

In high-risk industries such as chemical processing, pharmaceuticals, and petrochemicals, single-layer sight glasses often suffer from cracking, leakage or sudden failure—exposing operators to hazardous fluids and causing unplanned downtime. Lumistar's Safety Double-Layer Sight Glass addresses these critical pain points with a robust two-wall design and built-in safety features, ensuring uninterrupted, clear observation and maximum process security.

Safety double-layer sight glass Product Performance
Application:	For viewing of internals of pressure vessels, silos, stirred vesselsseparators, pipelines and other normally enclosed systems.Continuous monitoring for leakage is possible with externallyfitted pressure gauge.
Connection flange:	PN10/16
	The design of the supporting spacer ring ensures that each ofthe two glasses discs is able to withstand the maximum ratedoperating pressure and max. permissible temperatureindependently of the other.
Combination:	with Lumistar spotlights for explosion-proof and non-explosion-proof areas. Matching threaded apertures are provided on the flange cover for fixing the spotlights.
Operating environment:	pressure resistance:10bar (higher pressure resistance can be customized)
Operating temperature:	150℃with toughened Sodalime to DlN 8902
	280℃with borosilicate glass to DIN7080 (other higher grades of high-temperature resistant glass can be customized,
