Two-colour portable pyrometer KELLER CellaCombustion PT 147 from 700 up to 1700 °C for sooty flames temperature measurements

The CellaCombustion PT 147 is a special pyrometer for non-contact temperature measurement of sooty flames in coal-fired power stations and incineration plants. The measurement and signal processing, both based on the two-colour method, detect the heat radiation of the soot emitting particles of the flame in the near infrared range at two wavelengths. In order to correct the influence of the wavelength-dependent radiation properties of the soot particles and the optical density of flames, a special algorithm is used during the temperature determination. The flame temperature can be used to control the burnout in the furnace operation in order to reduce pollutant emissions and minimize slagging of the combustion chamber walls.

Special features:

• Measuring range 700 to 1,700 °C
• focusable lenses for exact adjustment of the measuring distance
• broadband anti-reflective precision lens
• LED display
• standard feature: USB interface
