The invention relates to a fiber optic measuring apparatus and a related method which includes a number of sensors which are integrated in a cable and detect a mechanical load, a temperature and/or corrosive gases, characterized in that the sensors are supplied with light from a source and the sensors form a fiber optic network.

Fiber optic measuring apparatus

A sensor element for detecting mechanical state variables contains at least one optical waveguide having at least one fiber Bragg grating, and at least one planar optical filter element to which light exiting the optical waveguide can be fed to at least one measuring device for determining an intensity ratio of a Stokes and an anti-Stokes lines and/or a propagation time of an optical signal. A method for detecting mechanical state variables uses such a sensor element running along a measuring section, wherein light having at least one predefinable mean wavelength and a predefinable spectral width is coupled into the optical waveguide and light reflected and/or scattered in the optical waveguide is fed to at least two measuring devices, measuring the intensity of the light exiting the optical waveguide in selected spectral ranges, and measuring an intensity ratio of a Stokes and an Anti-stokes line and/or a propagation time of an optical signal.

Sensor element and method for the production thereof and use thereof

Disclosed is a method for the contactless measurement of an offset of the functional components of a travel path of a magnetic levitation railway driven by a linear motor with the help of at least one optical triangulation system () that can be moved along the travel path. Said method is characterized in that at least two triangulation sensors () per measuring instrument for the functional components are moved along the travel path at a determined speed and alternately operate as a measurement sensor and as a reference sensor, i.e. using a radiation source in the ultraviolet, visible, or infrared spectral range, said triangulation sensors () being fixedly mounted on a movable support () and being geometrically offset. In said method, the diffusely reflected light is absorbed at a specific angle of observation, and the position of the light incident on the measurement sensor is used for determining the offset, said process being carried out at a scanning rate that detects measurement points within a screen of &#x3c;1.5 mm.

A device is provided for installing at least one linear motor line in the grooves () of an inductor () which is situated underneath a cover plate (). The device includes a vehicle () which can be moved on the cover plate (), a supply () of line (), a device () for forming the meander of the line (), a device () for drawing the line () from the supply () and for delivering the line () to the device () and a tool () for pressing the line () into the grooves (). The line may be installed automatically, even if the spacing of the grooves varies in dimension, by providing for an assembly slide () which can be moved in relation to the vehicle (). The slide is located at least partially under the cover plate () and the device () and tool () are located thereon. A measuring device () for measuring the position and the spacing (A) of the grooves () is also provided, as is a computer for processing the measuring data and for controlling the position of the assembly slide (), the forming device () and the tool (). A corresponding method is also provided for installing at least one linear motor line.

The invention relates to a linear motor for a linear drive mechanism of a magnetic levitation transport system. Said linear motor comprises a plurality of inductor supports () which are arranged in a row and which have grooves () crosswise to the longitudinal direction, said grooves being substantially equal distances apart from each other; and at least three linear motor lines (), which are wound into windings () in a meandering shape and which are located in the grooves () in sections. Said coils () have winding heads () situated a distance (A) apart. The invention solves the technical problem of producing the windings continuously and economically by providing that the lengths (A') of the winding heads () of the of the at least three linear motor lines () are extended at a point of discontinuity () between two adjacent inductor supports ().
