Description

Technical Field

[0001] This utility model relates to precision temperature measuring equipment, and more particularly to an integrated temperature measuring optical fiber for use in precision instruments. Specifically, it relates to a cap in an optical fiber device for temperature measurement and the optical fiber containing the cap. Background Technology

[0002] In various existing precision instruments, the components used to power them must possess high precision characteristics, such as matching dimensions and structures, sufficiently small size, and the ability to meet temperature measurement requirements. Based on these requirements, temperature probes adapted to precision instruments are constantly being designed. For example, Chinese utility model patent application number 202220653343.8, entitled "An Integrated Fiber Optic Temperature Probe Assembly," provides an integrated fiber optic temperature probe. This probe employs a fiber optic probe structure, using a probe rod as a clamping part to hold the fiber optic probe, and a cap is placed at the end of the fiber optic probe. In operation, the cap directly contacts the object being measured, such as a substrate or hot plate, thereby conducting temperature through the cap. This allows the electrical processing device connected to the other end of the fiber optic cable to obtain the temperature conducted through the fiber, thus achieving temperature measurement.

[0003] In the solution provided in the aforementioned patent application, the cap is a regularly shaped cap, similar to a hollow cylinder. The cap is typically fastened directly to the outside of the tail end of the clamping part, and the fiber optic probe is flush with the tail end of the clamping part, so that the inner side of the cap contacts the fiber optic probe when the cap is fastened to the clamping part. Correspondingly, in the working state, the outer side of the cap, i.e., the top of the cap, directly contacts the object being measured.

[0004] This solution already provides a relatively perfect solution. However, as the requirements for precision instruments continue to increase, there is a growing demand for fiber optic temperature measurement devices with faster response times, but the current structure has already reached its limit in terms of temperature measurement response speed.

[0005] From the perspective of process improvement, a new solution is needed to improve the temperature measurement response speed of the temperature-sensing optical fiber. Utility Model Content
