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.

integrated air purge
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 LumaSense
offers several digital displays which can also be used for
remote parametrizing of the pyrometer.

Sighting
For exact measurement of the object temperature the pyrometer must be aligned correctly onto the object.
For this alignment the pyrometers are equipped with a laser targeting light (IN 5/5 plus optional). This laser
enables the simple and accurate alignment even onto small objects. Pyrometers without laser targeting light
are normally used for measurement of bigger objects for which exact alignment is not absolutely necessary.
These pyrometers can be aligned only with the thermal method:

Alignment with laser targeting light
The laser point marks the center of the spot, not the exact size. The correct
focusing distance with the smallest spot size is achieved when the laser
point has its smallest size. The laser does not effect the temperature meas-
urement.
The laser targeting light can be activated either by pressing the button at
the rear side of the housing, by using an external contact (see 4.1 Pin as-
signment for the connector on the back of the pyrometer), or with the
InfraWin software. The laser can be switched off by pressing the button
again or it is automatically switched off after approx. two minutes.
Warning: To reduce the risk of injury to the eyes, do not look directly into the
targeting laser and do not point the targeting laser into anyone's eyes.
The instrument is equipped with a class II laser that emits radiation.
Note:
The laser warning signs on the pyrometer should be easily viewable at all times,
even after it has been installed.
Note:
To prevent the damage of the laser, the pilot light switches off automatically if the
internal temperature of the device exceeds approx. 50°C (it can switched-on again,
if the internal temperature is lower than 50°C).
