Connecting heat resistant joint fiber to ambient temperature fiber
・Use the following procedure to connect ambient temperature fiber.
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 ambient temperature fiber.
2. Mount the heat resistant joint fiber and ambient temperature 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 ambient temperature fiber to the mounting plate using the included metal nuts, use the procedure below.
•The mounting plate thickness needs to be 1 mm or less.
Procedure
1. Remove the protective tube from the ambient temperature 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 ambient temperature fiber using the same procedure from <Connecting heat resistant joint fiber to ambient temperature fiber>
4. Tighten the metal nut mounted in Procedure 1 to the mounting plate.
<Operating Temperature>
・In order to protect ambient temperature fiber and Fiber-Optic Sensor, keep the heat resistant joint fiber at least 100 mm from the boundary of the ambient temperature as shown in the diagram below.
Usage notes
・In order to protect Fiber-Optic Sensor, keep the heat resistant fiber part at least 150 mm from the boundary of the ambient temperature as shown in the diagram below.
・Do not directly expose Fiber-Optic Sensor 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.
