Fiber optic pyrometer PYROSPOT DGAF 11N

digital°CRS485

The digital pyrometers PYROSPOT DGAF 11N are developed for temperature measurements from 350 °C on silicon and for LASER application in industry and research. Due to a special narrow-band spectral range the silicon, that is otherwise permaeble for infrared radiation, can be measured exactly in a wide temperature range with almost constant emissivity. Also for application on metal surfaces that are machined with LASER the PYROSPOT DGAF 11N is the best choice. The wavelength of many LASER is outside of the spectral range of the pyrometer so that the temperature measurement is not influenced by the LASER. The additional use of mostly expensive LASER blocking filter lapses in this way. The solid body with fibre optics cable allows usage even under rough environmental conditions. The bright temperature display is visible even over long distance. With a fast response time of only 2 ms (t95) these pyrometers are also suitable for fast measuring processes. The vario or fixed optics for fibre optical head realizes spot sizes from 0.7 mm diameter. Special vacuum lead-throughs or variants with quartz or sapphire rod are available, too. The temperature linear standard output signal of 0/4 to 20 mA allows easy implementation in existing measurement and controll systems. The device is equipped with a galvanically isolated RS-485 interface which allows parameterising and software evaluation even in bus systems.
