Summary: | The invention provides a fiber bragg grating inclinometer and belongs to the technical field of sensing. The fiber bragg grating inclinometer comprises a shell and also comprises an elastic beam, a force amplifying assembly, a first magnet and a second magnet which are arranged in the shell; the elastic beam is horizontally arranged at an upper part of the shell, one end is connected with an innerwall of the shell, and the other end is a free end; a fiber bragg grating for monitoring the elongation of the elastic beam is attached to the elastic beam; the force amplifying assembly is located below the elastic beam; the first magnet is located below the force amplifying assembly and is connected with the free end of the elastic beam through a rigid wire winding around the force amplifying assembly; the second magnet sleeves the first magnet and is in clearance fit with the first magnet; the second magnet is fixedly arranged in the shell, and the magnetism of the second magnet repels themagnetism of the first ma |
