Pyrometer SD with separate electronics

Stationary pyrometers of the OKSD series measure the temperature of object contactless and give an analog output signal. For the measurement on different materials several variants are available for temperature ranges between -40 and +2500 °C. The OKSD series has been designed for control and monitoring tasks in different industrial sectors.

Application areas

  • Temperature monitoring in presses

  • Process control in the paper or plastics industry

  • Temperature monitoring in the food industry

  • Heating and air-conditioning

  • Electrical equipment, electronics

  • Road construction

  • Chemical industry

  • Furnace construction

  • Research and Development

  • Steelworks and rolling mills

  • Forging

  • Presses

  • Soldering, sintering and hardening


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.

  • Extensive range of accessories

The electronics box has a display to show temperature values and adjust parameters. can be displayed Through the multilingual windows software – associated with the interface cable - it is possible to adjust the measurement range and emissivity, as well as to display the temperature values in °C / °F, evaluate and record them. Also max and min. storage value and the measuring rate can be set. Versions in different cable lengths are available. A comprehensive range of accessories allows the adaptation to different operating conditions.

Reading and programming at the device display or with a PC via software

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

  • temperature display °C / °F

  • measurement range setting

  • emissivity setting

  • maximum value memory

  • setting time (95% time)

  • 0/4-20 mA output function

  • switching outputs

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.
