Pyrometer CellaCombustion PK 73

Article description

The CellaCombustion PK 73 measures at a special wavelength at which the chemical components of the hot combustion gas have a high optical density. These devices are used in large combustion plants such as thermal waste disposal plants and coal-fired power plants. The new generation of the CellaTemp® PK pyrometer series is equipped with a smart function, the vitality indicator.
This is a self-monitoring, analysis and reporting technology (SMART), i.e. a function for self-monitoring, analysis and status reporting. The vitality monitor continuously records all relevant operating data. As part of preventive maintenance, this enables the pyrometer to autonomously signal the optimum time for a service check and calibration, depending on the operating conditions.

Special features:

Measuring range 500 to 2,500 °C
small/compact design
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
2 x switching outputs PNP open collector
very simple mounting via M30 central thread
large and bright LED display
