The PSC Fidelis F3 Series is a small, robust range of 1-color infrared pyrometers with digital signal processing, stainless steel housing, and a wide temperature range from 50–1800°C. Designed for accurate, reproducible non-contact temperature measurement across steel, glass, ceramics and semiconductor applications.
The Process Sensors FIDELIS Series is a range of small, robust, 1-color non-contact infrared pyrometers combining digital signal processing with a stainless steel housing. Digital microcontroller processing delivers 100% reproducibility of readings through mathematical integration of set parameters and continuous ambient temperature compensation, allowing quick readjustment at any time. FIDELIS Series pyrometers are designed for ambient temperatures between 7°C and 70°C (45°F to 158°F), suiting a wide range of industrial temperature measurement applications.
Suited to induction heating, steel and metals, semiconductor wafers, kilns, cement and lime, vacuum furnaces, welding and brazing, ceramics, additive manufacturing, composites, sintering, molten glass, and research and development.
