3.3 Fiber optics
The fiber optics is consisted of the single-core quartz fiber and two optical connectors at both ends. Two
types of the sheath are available (Ref. [9.3 Fiber optics] in [9. General specifications])
1) Fiber optics covered by heat-resistive material with glass wool over braided. The maximum working
temperature is 150°C.
(Model: IR-FL
H
)
2) Fiber optics covered by heat-resistive material with glass wool over braided, and further covered by
metal flexible tube sheath. The maximum working temperature is 150°C.
(Model: IR-FL
N
)
[Labels and direction of fiber optics]
CHINO label side: Connect to the lens assembly
Fiber optics serial no. label side: Connect to the thermometer
Caution
The maximum working temperature of the fiber optic assembly is 150ºC.
Don’t use it in places higher than 150ºC.
When adding strong power to the neighborhood of an arrow mark, fiber optics is
damaged. Don’t add the strong power of 40 N over.

Warning
The fiber optics has a direction of the thermometer side and the lens assembly side,
and the thermometer has been calibrated with the correct directional fiber optics.
If you connect the fiber optics with the opposite direction to the thermometer, you
will have an indication error.
By referring to the [Labels and direction of fiber optics] shown below, connect the
fiber optics with the proper direction.
