The key feature in selecting a pyrometer is its spectral range, as this must be related to the proper-ties of the specific material and to the application. A pyrometer with wavelength as short as possible is recommended, if you want to achieve high accuracy.

Various optical systems ensure best adaptation to the object size. To avoid reading errors, it is necessary to choose a measurement spot that can always be completely filled by the object. The table shows for the different types the spot dimension in relation to the object distance.

The OKSD series features a separate sensor head which can be used at ambient temperature of up to 125 °C or 180 °C. Installation in limited spaces is possible thanks to its compact stainless steel M12 housing. All models are provided with an analog output 0/4-20 mA, two relay outputs, two inputs and a RS 485 interface. The electronics box has a display to show temperature values and adjust parameters.

Keyboard and display allow the display and adjustment of the following parameters:

Settings can be changed using the software via RS 485 interface. The software runs under Windows. The user guidance system is multi-lingual and largely self-explanatory. Besides parameterization, the software also offers the opportunity to evaluate and keep records of the measurement data.
