4.1 System Design/Principle of Operation
Fig. 1 shows the basic structure of the pyrometer. The basic parts of a pyrometer are the
The infrared radiation coming in from the object to be measured is gathered by the lens.
spectral range to enter.
The rays then pass through to the detector which transforms the infrared radiation into
electric signals.
These signals are then linearised in the signal processing unit and changed into a stan-
dard output signal which can then be read in the display and be used for process
control.
The operating elements as well as the connections/interfaces are located at the back of
the pyrometer (see pages 10 to 11) .
