2 Introduction
2.1 Appropriate use
The IS 12-Al is a special version of the pyrometer IS 12, designed for the measurement of
aluminum. The robust die-cast housing with protection class IP65 is designed for the use in
industrial environments.
The instruments IS 12-Al/S is equipped with an integrated scanner which moves the measuring
beam adjustable up and down up to 4°.
2.1.1 Application
The IS 12-Al is a special development of the well proven IS 10-Al for
aluminum applications in temperature ranges between 350 and
1050 °C.
Conventional pyrometers – even 2-color pyrometers – are not able to
measure the temperature of aluminum correctly due to the special
physical properties of aluminum. To avoid the negative influence of
these properties in the non-contact temperature measurement the
IS 12-Al operates in a special spectral range. In this spectral range solid
aluminum has a very high and stable emissivity between 30 and 43%.
That is why the instrument is suitable for aluminum applications such
as extrusion, rolling, billet heating and other heating processes.
Note: Due to physical reasons the IS 12-Al is sensitive to light at the beginning of the
temperature range. This sensitivity decreases with increasing temperature. In
applications with low temperatures (at the start of the temperature range) the
measuring area has to be screened against light to avoid its influence (see drawing).
