Pyrometer CellaTemp PX 35

Article description

The CellaTemp® PX 35 has a very short-wave and narrow-band spectral sensitivity. Therefore, the pyrometer reacts to interfering influences such as signal weakening by dust, vapour or smoke in the pyrometer's field of view, to soiling of the protective window or to emissivity fluctuations of the measuring object much less than a conventional spectral pyrometer. Metals have the physical property that the emissivity increases with shorter radiation wavelengths and higher object temperatures. Therefore, the CellaTemp® PX 35 is ideal for precise measurement of metals and very hot objects. In addition, the pyrometer is used to measure thin semiconductors, as semiconductors have very good radiation properties in the pyrometer's special spectral range. For wavelengths > 1 µm, silicon is transparent, so a standard pyrometer would measure the temperature of the material behind it through the silicon.

Pyrometer CellaTemp PX 35

Emissivity calculator

The correct emissivity to be set on the pyrometer is calculated from the measured value displayed on the pyrometer, the true object temperature, the emissivity preset on the pyrometer and the ambient temperature (necessary for some types).
From the true object temperature, the emissivity of the measurement object, the emissivity set on the pyrometer and the ambient temperature (required for types), the measured value calculated by the pyrometer is displayed.
