  • Patent number: 4778770
    Abstract: A sensor element arrangement for a pyrodetector has a concave mirror with a sensor element arranged at a focus of the concave mirror and further sensor elements arranged laterally therefrom. Electrodes of both polarities are present on each side of the film, these electrodes being respectively separated from one another by quasi-meander-like, metal-free strips which engage into one another in the form of hook portions. The electrodes on the upper side reside opposite corresponding electrodes on the lower side for the formation of the sensor elements, and these electrodes are connected to one another at edge regions by connection lines. The sensor element arrangement together with the film and the connection lines is surrounded by a retaining frame which is insertable into the mounting of the concave mirror in centered and adjusted fashion.
    Type: Grant

  • Patent number: 4716294
    Abstract: A pyrodetector having a concave mirror containing a sensor element arranged in a focus thereof. The sensor element is on a film and is distinguished by a compact structure. The concave mirror is formed of a body having a rectangular cross-section, of a reflector part, and of sidewalls positioned perpendicularly relative to one another. An opening is provided in a reflector portion through which a retaining part provided with plug pins is inserted. The concave mirror, an evaluation means arranged outside of the concave mirror behind the reflector portion, and a honeycomb lattice and a covering are accommodated as an overall arrangement in a housing.
