Infrared thermometer CellaCombustion PK 72

monochromaticwith LED display°C

Product description:
The CellaCombustion PK 72 performs non-contact temperature measurement at a wavelength where hot carbonaceous combustion gases exhibit high optical density and strong radiative properties. The instrument is designed to measure flue gas temperature in gas-fired boilers and small combustion systems, and is also suitable for larger combustion plants such as coal, biomass and waste incineration facilities. The CellaTemp® PK series includes a vitality indicator (SMART) for continuous self-monitoring, analysis and status reporting. The vitality monitor logs relevant operating data to support preventive maintenance and can autonomously signal optimal times for service checks and calibration depending on operating conditions.

Special features:

• Measuring range 400 to 2000 °C
• Small, compact design
• Universally configurable switching outputs
• High optical resolution with precision lenses
• IO‑Link interface
• All parameters adjustable via sensor pushbuttons or plant interface
• 2 × switching outputs, PNP open collector
• Very simple mounting via M30 central thread
• Large, high‑visibility LED display
