The PSC-SRF11N is a 2-colour fibre optic pyrometer for industrial applications, covering 600°C to 3000°C. Its rugged fibre optic cable and lens assembly operate in ambient temperatures up to 250°C without cooling, with parameters adjustable directly via on-device push buttons.
The PSC-SRF11N is a 2-colour fibre optic pyrometer ideal for demanding industrial applications, with various temperature ranges spanning 600°C to 3000°C. As the higher-temperature sibling to the PSC-GRF11N, it’s suited to the hottest process conditions where a fibre optic sensing head is required to keep sensitive electronics away from extreme heat.
Suited to steel forming, induction heating, furnace and molten metal applications, and other extreme-temperature industrial processes where a standard sensor head can’t withstand the ambient conditions.
