3.4.3 Optical head
The FSMA connector on the side of the
optical head doesn’t need a special
justification if bold together.
3.5 Optical head
Depending on the application, the instrument will be delivered with a small or a big optical
head.
Type
Ι
(small optical head): With the very small dimensions the
optical head I is suited for use in confined spaces. The optics is adjusted
to one of the measuring distances mentioned in the table 3.5.1. The
mentioned spot size will be achieved in exactly this distance (other
distances on request).
Type
ΙΙ
(optical head, focusable): With the focusable optical head II
each measuring distance can be adjusted within the mentioned limits
to achieve the smallest spot size in the required distance. The spot size
at the shortest and longest distance is mentioned in the following
table 3.5.1 Spot sizes at intermediate distances must be calculated by
interpolation.
Type
ΙΙ
(optical head, fixed adjusted): The fixed adjusted optical
head II has a similar size as the focusable optical head but with a fixed
focusing distance similar to type I (see table 3.5.1).
Note: The optical heads can be changed against another from the same type.
A recalibration of the pyrometer is not necessary.
