Mounting Method
-
Connecting heat resistant joint fiber to ambient temperature fiber
- Use the following procedure to connect ambient temperature fiber.
Procedure
-
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.
-
Mount the heat resistant joint fiber and ambient temperature fiber using a lock nut.
Note 1: Do not secure the lock nut using the plastic nut and spring washer from Procedure 1.
-
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
- 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.
- Insert the tip of the fiber into the mounting plate.
- 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>
-
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 100 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.
