Product Overview

The ABB SF810INT-LOS-UV-TL is a highly integrated line-of-sight flame detector.
It uses an ultraviolet (UV) sensor to detect flames and features a built-in temperature sensor (T) for additional monitoring.
Equipped with a lens cleaning (L) function, it ensures reliable operation even in dusty or contaminated environments.
