Pyrometer CellaTemp PKF 26

Article description

The CellaTemp® PKF 26 has separate electronics and measuring head. The infrared radiation is transmitted to the electronics via a fibre optic cable. The measuring head can be used without cooling in ambient temperatures up to 250 °C. This version can also be used in cramped mounting conditions or high electromagnetic fields. The length of the fibre optic cable can be up to 50 m.

Special features:
  • Measuring range 300 to 1
  • 600 °C -- fibre optic cable version up to 50 m length possible -- switching output universally configurable -- high optical resolution due to precision lenses
  • IO-Link interface -- all parameters can be set via pushbutton on the sensor or via interface from the plant control system -- test function can be triggered by pushbutton or control signal -- very simple mounting via M30 central thread
  • large and bright LED display

Emissivity calculator

The correct emissivity to be set on the pyrometer is calculated from the measured value displayed on the pyrometer, the true object temperature, the emissivity preset at the pyrometer and the ambient temperature (required for some instrument types).
The value displayed by the pyrometer is calculated from the true object temperature, the emissivity of the measurement object, the emissivity set on the pyrometer and the ambient temperature (required for some instrument types).
