Connecting heat resistant joint fibers to Ordinary temperature side fibers
•Use the following procedure to connect normal temperature side fibers.
Procedure
1. Attach the plastic nut included with the heat resistant joint fiber and spring washer as far as possible on the fiber tip of the normal temperature side fiber.
2. Mount the heat resistant joint fiber and normal temperature side fiber using a lock nut.
3. To prevent the lock nut from becoming loose, secure using the plastic nut used for mounting in Procedure 1.
If mounting connecting parts to the mounting plate
・If securing parts that connect the heat resistant joint fiber and normal temperature side fiber to the mounting plate using the included metal nuts, use the procedure below.
•The mounting plate thickness needs to be 1 mm or thinner.
Procedure
1. Remove the protective tube from the normal temperature side fiber, attach the included metal nut from the tip of the fiber and move it to the fiber part.
2. Insert the tip of the fiber into the mounting plate.
3. Connect the heat resistant joint fiber to the normal temperature side fiber using the same procedure from <Connecting heat resistant joint fibers to normal temperature side fibers>
4. Tighten the metal nut mounted in Procedure 1 to the mounting plate.
<Operating Temperature>
•In order to protect normal temperature side fibers and Fiber-Optic Sensors, keep the heat resistant joint fiber at least 100 mm from the boundary of the normal temperature side as shown in the diagram below.
•Do not directly expose Fiber-Optic Sensors to radiation heat or hot air.
•The tip bracket of the heat resistant fiber (up to 350°C) and stainless steel sheath may change color when used at high temperatures, but this does not affect their detection capability.
Notes for usage
・In order to protect Fiber-Optic Sensors, keep the heat resistant fiber part at least 150 mm from the boundary of the normal temperature side as shown in the diagram below.
・Do not directly expose Fiber-Optic Sensors to radiation heat or hot air.
・The tip bracket of the heat resistant fiber (up to 350°C) and stainless steel sheath may change color when used at high temperatures, but this does not affect their detection capability.
