ABB SF810INT-FOC-UV-T-L UV Flame Scanner

Overview

The ABB SF810INT-FOC-UV-T-L is a high-performance UV flame scanner from the Uvisor™ SF810 series. It monitors industrial burners reliably in harsh environments. It uses a fiber optic cable to detect flame presence, making it ideal for corner-fired tilting burners and deep windbox installations. Therefore, it does not require a direct line-of-sight. The scanner ensures precise flame discrimination and continuously monitors flame quality.
