Stationary pyrometers of the OKS 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 OKS series has been designed for control and monitoring tasks in different industrial sectors.
Temperature measurement of glass surfaces
Material monitoring in presses
Process control in the paper or plastics industry
Temperature monitoring in the food industry
Temperature control of objects in furnaces or behind gas flames
Heating and air-conditioning
Electrical equipment, electronics
Research and Development
Steelworks and rolling mills
Soldering, sintering and hardening
The key feature in selecting a pyrometer is its spectral range, as this must be related to the properties 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 how the spot dimension changes in relation to the object distance.
The incorporated LED light makes precise alignment on the object to be measured easier, as the light dimension approximately represents the measurement spot. For pyrometers without LED light we offer a separate Laser pointer.
All models are provided with a connector with 4-20 mA analog output in 24 V DC, 2 wire, current loop system. They also have a USB interface with galvanic isolation. A USB interface cable is available as option for stand-alone operation of the pyrometer without additional power supply. 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. Separate connection cables are available in several lengths. A comprehensive range of accessories allows the adaptation to different operating conditions.
