Non-contact temperature measurements with the new pyrometers of the PYROSPOT series 10

The digital pyrometers of the PYROSPOT series 10 from DIAS Infrared have proven themselves for many years for precise temperature measurements from 0 °C to 3000 °C in industry and research. For different applications not only different temperature measuring ranges, but also adapted spectral ranges are necessary. From a physical point of view, temperature measurements should be operated as short-waved as possible to reduce failures due to emissivity reasons. In addition spectral ranges should be used in which the target ‘s emissvity is high and the environment has only less disruption.Therefore, the PYROSPOT series 10 includes a large number of pyrometer types, which have now been expanded with new variants (marked in “red”). Ratio pyrometers are marked in “blue”, which are suitable for measurements on objects with variable or unknown emissivity and which work in two directly adjacent spectral ranges.

All pyrometers of the PYROSPOT series 10 are in an IP65 compact housing.Thanks to control buttons placed directly on the device, the complete parameterization of the pyrometer can be realized on site .An integrated, easy-to-read display is used to show the measured value and parameters. A variety of accessories also allow operation in harsh environments, such as cooling jackets, air purge units, and special ATEX explosion protection housings. Vario optics with a very small measuring field diameters from 0.7 mm allow optimal adaptation to local conditions. To align the pyrometers to the target, series 10 devices have either a LED or laser pilot light, a through-lens sighting, or a color video camera. With a response time t95 from 1 ms, the pyrometers are also suitable for very fast measuring tasks.

All pyrometers of PYROSPOT series 10 have a temperature linear 0/4 to 20 mA output, a galvanically isolated RS-485 interface (data protocol Modbus RTU), a maximum/minimum value storage and also a galvanically isolated switching output. Thereby an easy implementation into measurement and control systems is possible. For integration into local networks the Ethernet Interface Box DCUIoP is available. With it, a wireless parametrization of the pyrometers can also be set. Thanks to the powerful software PYROSOFT Spot and PYROSOFT Spot Pro the evaluation and further processing of the pyrometer data can take place. At the same time, the parameterization of the pyrometers can also be carried out with the help of this software.
