Abstract: The invention relates to a device for the IR-spectrometric analysis of a solid, liquid or gaseous medium. The device includes a process probe, which has a reflection element. The device additionally includes a linear variable filter, at least one detector element, and a control/evaluation unit. At least one light source is also provided, the light of which is coupled into the reflection element via a collimating optics. At least one optical waveguide having a light input section and a light output section is provided. The light is guided via the light output section of the optical waveguide into a defined region of the linear variable filter. The detector element and the linear variable filter are arranged movably relative to one another over approximately the length of the linear variable filter. The control/evaluation unit determines the spectrum of the medium on the basis of the measured values delivered from the detector element.

Abstract: A gas sensor module includes: a primary sensor for the registering of a gas concentration; a digital data memory for storing sensor data or process data; and an interface for connecting to a superordinated unit for energy supply of the gas sensor module and for data exchange between the gas sensor module and the superordinated unit, with the interface being a contactless interface. A transmitter module operates at least one such gas sensor module and includes: a contactless interface for data exchange with the gas sensor module and for energy supply to the gas sensor module; and a communications circuit for output of at least one signal dependent on the measured data.

Abstract: An electrical device having components (1, 2, 3) that are arranged in a casing (4; 10) and are electromagnetically shielded in an outward manner. In the casing, spaces provided between the casing and the components as well as between the components themselves are completely filled with plastic parts (5, 6; 13) provided with ferrite particles (9). These plastic parts are preferably provided in the form of shaped plastic parts in which the components are held with form fit.
