Fiber optic
The fiber has a blue or red mark for
correct connection to the pyrometer.
The color mark must be mounted on
the pyrometer’s side.
The fiber optic is equipped with a
special connector which allows it to
fix the fiber only in one position.
Please notice that the connector of
the fiber with the pin is fixed in the
correct position before plug and
socket can be bold together.
Note:
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.
Ambient temperature
The fiber and optical head can withstand ambient temperatures up to 250 °C without cooling on
the side of the optical head.
Serial number / fiber replacement
The original fiber has a serial number which is also on the pyrometer’s housing. If required, the
fiber can be replaced by a new original IMPAC-brand fiber. In this case, the pyrometer has to be
calibrated together with the fiber (service).
