The Advanced Energy Impac® High Speed 740 pyrometers offer the extremely fast 6 μs response time and are ideal for high-speed applications. IGA 740: The compact IGA 740 is available with either focusable or macro optics. Use focusable optics featuring a measuring distance between 450 and 3000 mm to achieve small spot sizes. And, depending on the temperature range, macro optics provide a spot size of only 0.7 mm or 1 mm at fixed distance. IGA 740-LO: The IGA 740-LO uses an optical fiber and optical head for transmitting radiation. The fiber and optical head are unaffected by electromagnetic interferences (e.g. induction). They can be used in very high ambient temperatures up to 260°C without cooling. The IGA 740 and IGA 740-LO pyrometers are also available as temperature measuring stations. These include a bench unit, digital display, USB interface, power supply, connecting cable, software, and a 1.5 m optical fiber (-LO version).
