Mechanical installation

6.1

Accessories (option)

Numerous accessories guarantee easy installation of the pyrometers. The following overview shows a selec-
tion of suitable accessories. You can find the entire accessory program with all reference numbers on sec-
tion 13.2 Reference numbers.
Mounting:
For easy mounting and aligning the pyrometer to the
measured object an adjustable mounting angle is avail-
able.
Cooling:
The completely covered water cooling jacket made from
stainless steel protects the pyrometer if exposed to a hot
environment. It is designed for ambient temperatures up
to 180°C.
Miscellaneous:
The air purge protects the lens from contamination with
dust and moisture. It has to be supplied with dry and oil-
free pressurized air and generates an air stream shaped
like a cone.
The pyrometer can be easily fixed on a vacuum chamber
with the KF 16 vacuum support with sighting window.
Displays:
For temperature indication of the pyrometer IMPAC offers
several digital displays.

Optics

The pyrometers are equipped ex works with one of the following optics. These lenses are focusing to certain
distances. In these distances each lens achieves its smallest spot size. The spot size will enlarge in any
other distance (shorter or longer). Please notice that the measuring object must be as least as big as the
spot size.
The name of the optics (e.g. optics 300) shows the measuring distance in mm (e.g. 300 mm, measured from
the front of the lens) in which it has the smallest spot size (e.g. 6 mm).
The following drawings show the size of the spots in mm in dependence of the measuring distance. Values
between the mentioned data can be calculated by interpolation. The spot size for measuring distance 0 is the
aperture diameter D of the optics.
