Near-infrared pyrometer CellaCombustion PX 47

with LED display°CIO-Link

Product description:
The CellaCombustion PX 47 is a two-colour pyrometer for non-contact temperature measurement of sooty flames in coal-fired power plants and incineration furnaces. Using dual-wavelength detection in the near infrared (0.8 / 1.05 µm) and a dedicated correction algorithm, the instrument compensates for wavelength-dependent soot radiation and flame optical density to provide reliable flame-temperature data for combustion control and emission reduction.

Applications:

• Combustion control in power plants and waste incineration
• Burnout monitoring and slagging prevention
• Process monitoring in continuous high-temperature furnaces

Key features:

• Measuring range 700–1700 °C
• IO-Link interface for parameterization and diagnostics
• Focusable optics for precise adjustment of measuring distance
• Broadband anti-reflective precision lens
• 4-digit red LED display readable at distance
• Test current output for diagnostics
• 1 analogue output (0/4–20 mA) and 2 switching outputs
• Source freely configurable
