This product is a supporting installation fixture for OFSCN® fiber bragg grating (FBG) sensors, produced by DCYS. It is used for the installation and fixation of OFSCN® FBG strain sensors, FBG stress sensors, FBG displacement sensors, and other products such as serially connected FBG temperature sensors and FBG linear temperature sensing fire detectors. The fixture is characterized by its small deformation, convenience in use, and flexible installation methods, which include conventional screw installation as well as welding, adhesive bonding, and strapping.

The welding and adhesive bonding installation methods for OFSCN® capillary seamless steel tube series FBG sensors are not demonstrated here. The conventional screw installation method is described as follows:
1、Surface Preparation and Marking
Clean the installation surface thoroughly. Place the long fixing plate on the installation surface and mark the holes at both ends with a marker pen. Use a drill to create holes at the marked positions and insert plugs, then flatten them with a hammer.
Apply adhesive (this step can be omitted) to the contact area between the long fixing plate and the installation surface. Press the long fixing plate onto the surface (ensure that the holes in the long fixing plate align with the holes in the plugs), and tighten the screws. Proceed to the next step after the adhesive has cured.
2、Placement and Fixation of FBG Sensors
 |
Position the tail handle of the OFSCN® capillary seamless steel tube FBG sensor in the semicircular groove of the long fixing plate, and press the semicircular groove of the short fixing plate onto the sensor's tail handle. Finally, secure them with screws, clamping the tail handle of the OFSCN® capillary seamless steel tube FBG sensor (on the side closer to the fiber core) between the two fixing plates
3、Completed Installation
 |
Repeat the same process to secure the other end of the OFSCN® capillary seamless steel tube FBG sensor to complete the installation.
4、Important Notes during Installation
The OFSCN® capillary seamless steel tube FBG sensor usually has a certain pre-tension when it leaves the factory. Therefore, excessive pre-tension is not required during the installation process, but excessive pressure should also be avoided. Hence, it is important to straighten and secure the FBG sensor as much as possible during the installation process.
By following these steps, accurate measurement of physical quantities such as strain, stress, and temperature can be ensured for the OFSCN® capillary seamless steel tube FBG sensor at both ends.
