INFRATHERM pyrometer ISR 50-LO

6.3
Fibre
The infrared radiation is transmitted from the optics to the signal processor through a fibre optic cable almost
totally lossless. The fibre connectors are constructed in a very robust HD design (heavy duty).
Depending on the temperature range of the pyrometer
the fibre has a yellow, red or green mark for correct
connection to the pyrometer. This color mark has to be
mounted on the pyrometer’s side.
The fibre optic is equipped with a special connector on
the converter’s side which allows to fix the fibre only in
one position. Please notice that this connector with the
pin is fixed in the correct position before plug and socket
can be bold together.
Note: The light guide end of the fibre optic ca-
ble as well as the socket/connector and the opti-
cal head must always be protected with the caps
when not connected!

Ambient temperature
Fibre and optical head can be used in ambient temperatures up to 250°C without additional cooling (fibre at
converter side max. 125°C).

Note:

6.3.3
Serial number / fibre replacement
The original fibre 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 fibre optic
cable or the optical head are exchanged (service)!
6.3.4
HD optical head
The connector on the side of the optical head doesn’t need a
special justification if bold together.
For fixing and aligning the optical head different mounting
supports are available (see 6.4 Accessories (option)).
