Monochromatic pyrometer CellaCombustion PX 17

with LED display°C°F

Product description
The CellaCombustion PX 17 performs temperature measurement at a specific CO2-sensitive wavelength where hot carbonaceous gases exhibit high optical density and reliable radiative behaviour. It is designed for flue gas temperature measurement in gas-fired boilers, small combustion systems and similar industrial combustion processes.

Special features

• Measuring range 400 to 2,000 °C
• IO-Link interface for configuration and data exchange
• Focusable optics for precise adjustment of measuring distance
• Broadband anti-reflective precision lens (standard PZ 15.03)
• 4-digit red LED display readable from a distance
• Test current output for diagnostic purposes
• 1 analogue output (0/4–20 mA) and 2 switching outputs (Open Collector)
• Source (emissivity/transmittance) freely configurable
