The fiber has a color mark for correct connection to the pyrometer. This color mark has to be
mounted on the pyrometer’s side. On side of the optical head no mark or a black mark is
viewable.
Attention: The light guide end of the fiber optic cable as well as the socket/connector
and the optical head must always be protected with the caps when not connected!
Minimum Bending Radius
Red Blue Green
for short time (max. 250 °C): 50 mm 100 mm 150 mm
permanent (max. 250 °C) : 120 mm 300 mm 500 mm
wound up (max. 50 °C): 120 mm 300 mm 500 mm
Note: A hot fiber optic cable should not be exposed to continual movement!
Serial Number
The original fiber has a serial number which is also
on the pyrometer’s housing.
Attention: Faultless operation of the pyrometers is ensured only when using
components with the same serial number.
The system must be re-calibrated if the fiber optic cable or the optical head are
exchanged (service)!
Ambient Temperature
Fiber and optical head can withstand ambient temperatures up to 250 °C without cooling on the
optical head’s side.
3.3 Sighting
3.3.1 Laser targeting light
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.
This laser enables the simple and accurate alignment even onto small objects.
The laser marks the center of the measuring spot. The laser targeting light can be used during
operation without affecting the measurement.
The laser targeting light can be switched on and off either by pressing the button at the
housing or by using an external contact (see 3.1.1 Pin assignment for the connector on the back
side of the pyrometer) or via PC and the software InfraWin. After two minutes, the laser
targeting light switches off automatically.
If the converter cover is opened the laser targeting light can be switched with the button with
the symbol. When the laser targeting light is switched on, the display shows “PILT”.
