Connect The Optics; Ambient Temperature - KPM PROCESS SENSORS METIS M308 User Manual

|INFO|
To meet the high accuracy, the instrument should be recalibrated when replacing an optics or the fiber
optic cable.
|NOTICE|
Remove the protective caps from the pyrometer and optics and fiber just before installation
to keep the connectors clean and to prevent the ingress of dirt.
Keep the protective caps to be able to protect against dirt in any subsequent dismantling or storage.
Ambient temperature on
pyrometer's side is 100°C / 212°F max.
Ambient temperature on
optics side is 250°C / 482°F max.
The optical fiber has to be mounted true-sided:
▪ The colored heat shrink tube marker matches to the
pyrometer side.
▪ The optics fit on the side without marking
▪ Unscrew the light guide protective tube from the
pyrometer's housing
▪ Pull the protective tube somewhat about the light
guide on the colored side to avoid pulling it over the
complete fiber after fiber assembly.
▪ Remove the protective caps from the pyrometer and
optical fiber, insert the side with the turn protected
fiber connector to the pyrometer, and make sure that pin and
recess snap together.
▪ Tighten lock nut hand-tight (do not use a tool, otherwise the
screw or optical fiber can be damaged).
▪ Finally screw the protective tube back on the pyrometer
housing.

5.2.4 Connect the Optics

▪ Remove the protective caps from optical fiber and optics
▪ The fiber-optic connectors on the side of the optics does
not require special adjustment and is just plugged and
screwed
▪ Tighten lock nut hand-tight (do not use a tool, otherwise
the screw or optical fiber can be damaged).

Ambient Temperature

▪ M308, M309 and M316 are designed for ambient temperatures between 0 and 80°C / 32 and 176°F.
▪ M318 models should only be used up to 60°C / 140°F to maintain measurement accuracy.
▪ M323 is designed for ambient temperatures up to 70°C / 158°F.
▪ H3 models are permissible up to maximum 65°C / 149°F.
▪ Fiber optic devices can be exposed on optics and optical fiber to ambient temperatures between -20 and
250°C / -4 and 482°F without cooling, for the housing the same temperatures apply as for standard devices
(0 to 80°C / 32 and 176°F).
|INFO|
to avoid overheating of the laser targeting light or camera module:
▪ The laser targeting light is deactivated at an internal device temperature above 65°C (M3 devices) or above
60°C (H3 devices).
▪ The camera module is deactivated at an internal device temperature above 55°C.
Below that temperatures the sighting can be used again.
