Pyrometer CellaCast PA 81
Description
The CellaCast PA 81 was specially developed for measuring the temperature of liquid metals in the casting channels of blast furnaces and cupola furnaces. Furthermore, the pyrometer is used when transferring the metal from the melting or holding furnace into the transport ladle or casting ladle. The two-colour pyrometer is equipped with a separate optical measuring head and a fibre optic cable. The fibre optic cable and measuring head are insensitive to interference from electromagnetic radiation and can be used in ambient temperatures up to 250 °C without cooling. The variant with separate optical measuring head has advantages especially in confined spaces.
Special features:
Measuring range 800 to 2Ɛ °C
wear
and maintenance-free measuring system for temperature measurement in melting and holding furnaces as well as cupolas and blast furnaces
ATD function for filtering the temperature of the slag-free and oxide-free metal surface
two-colour measuring method for interference-free measurement in the presence of dust and vapour
high-resolution lens for reliable measurement even from a great distance
measuring head and fibre optic cable heat resistant up to 250 °C

Emissivity calculator
Calculation of the emissivity to be set
From the measured value displayed on the pyrometer, the true object temperature, the emissivity preset at the pyrometer and the ambient temperature (required for types), the correct emissivity to be set on the pyrometer is calculated.
