Beijing SOIL won the bid for Supplying safety monitoring instruments for the FAST project, the world's largest radio telescope

Five-hundred-meter Aperture Spherical radio Telescope is one of the nine national science and technology infrastructures reviewed and approved by the National Science and Education Leading Group. It is intended to adopt the unique design of Chinese scientists and the uniqueness of the karst depression in southern Guizhou. Terrain conditions, building a large, highly sensitive giant radio telescope with about 30 football fields.

Compared with its precursor — Arecibo — FAST has an advantage of a factor of 2 in raw sensitivity and a factor of 5-10 in surveying speed. FAST will also cover two to three times more sky area thanks to its innovative design of an active primary surface. A science instrument with an order of magnitude improvement in any of its capacities which is also able to explore new dimensions in parameter space is likely to generate unexpected discoveries.

Beijing SOIL successfully won the bid for the safety monitoring instrument of the project, and will provide vibrating wire and fiber grating safety monitoring instruments to the project, including SOIL spot welding strain gauge, Beijing SOIL arc welding strain gauge, fiber grating surface strain gauge, automatic acquisition unit, fiber grating demodulator, etc.

These equipment will monitor structural safety during construction and will be applied for health monitoring after the construction period.
