Installation of the Pyrometer
4.1 Location selection
Qualified operating person should do the installation. Location should be good enough from where pyrometer
should get continuous infrared radiation.
4.2 Ambient temperature
The allowed operation temperature for the pyrometer is 0°C to + 70°C at electronic side and 250°C (max) at fiber and
optical head. Therefore ambient temperature must not exceed this temperature range otherwise it may damage the
pyrometer / fiber and optical head.
4.3 Atmospheric conditions
The pyrometer cannot receive the full infrared energy for the measurement if atmospheric conditions like smoke,
dust or steam are present and hence it result in measuring error. An air purge unit can be helpful to avoid contamination
of the lens.
4.4 Correct Positioning of the pyrometer
To avoid measuring errors caused by a too big spot size the pyrometer must be fixed in the correct measuring
distance, so that the object under measurement fills the spot size.
4.5 Mechanical installation and Mechanical accessaries
Signal processor: To fix the signal processor box remove the top cover & mount it with the help of 2 mounting hole
