  Optisches Pyrometer mit zwei durch dieselbe Stromquelle geheizten   Glühfäden.

   Das Entstehen eines grellen Spiegelbildes im Gesichtsfeld des Beobachters lässt sich aber   schliess,     lieh   auch dadurch vermeiden, dass man den bandförmigen Glühfaden 2 um die senkrecht zur optischen

 der langen Achse des bandförmigen Glühfadens ist dabei die Verbindungslinie der Schnittpunkt der Diagonalen zu verstehen, die in den an beiden Enden des bandförmigen Glühfadens liegenden schmalen Rechtecke gezogen sind. 



   Die Erfindung ist nicht auf Pyrometer mit einem bandförmigen und einem an der Kreuzungsstelle   flächenförmig   verbreiterten Glühfaden beschränkt, sondern sie kann auch bei Pyrometern mit anders gestalteten Glühfäden sinngemäss angewendet werden, beispielsweise mit einem vollständig drahtförmigen Glühfaden und einem ganz oder nur an der Kreuzungsstelle bandförmigen   Glühfaden,   wenn auch in letzterem. Falle der oben erwähnte Lichteffekt in der Regel geringer sich bemerkbar machen wird. 



   PATENT-ANSPRÜCHE :
1. Pyrometer nach Patent Nr. 132916, dadurch gekennzeichnet, dass das Sichtbarwerden eines hellen Spiegelbildes des vorderen Glühfadens auf dem dahinterliegenden Glühfaden verhindert ist durch Abdeckung des Spiegelbildes durch die Verbreiterung des vorderen Fadens selbst oder durch eine solche gegenseitige   Schrägstellung   der Glühfaden, dass kein Bild im Gesichtsfelde entstehen kann.

  Optical pyrometer with two filaments heated by the same power source.
 EMI1.1

   The creation of a glaring mirror image in the field of vision of the observer can also be avoided, however, by moving the band-shaped filament 2 around the perpendicular to the optical
 EMI2.1
 the long axis of the ribbon-shaped filament is to be understood as the connecting line of the intersection of the diagonals, which are drawn in the narrow rectangles lying at both ends of the ribbon-shaped filament.



   The invention is not limited to pyrometers with a ribbon-shaped filament and a filament widened in the form of a flat area at the intersection, but it can also be used analogously in pyrometers with differently designed filaments, for example with a completely wire-shaped filament and a wholly or only ribbon-shaped filament at the intersection, albeit in the latter. If the above-mentioned light effect is usually less noticeable.



   PATENT CLAIMS:
1. Pyrometer according to Patent No. 132916, characterized in that a bright mirror image of the front filament is prevented from becoming visible on the filament behind it by covering the mirror image by widening the front filament itself or by tilting the filament in such a way that no image can arise in the field of vision.

Pyrometer nach Anspruch 1 mit mindestens einem an der Kreuzungsstelle -der Glühfäden flächenförmigen Glühfaden, dadurch gekennzeichnet, dass dieser Glühfaden so angeordnet ist, dass die Ebene der Fadenfläche mit der Längsrichtung des andern Glühfadens einen Winkel von 20-30 ein- EMI2.2 2. Pyrometer according to claim 1 with at least one at the intersection of the filaments sheet-like filament, characterized in that this filament is arranged so that the plane of the filament surface with the longitudinal direction of the other filament an angle of 20-30 EMI2.2 3. Pyrometer nach Anspruch 1 mit einem bandförmigen hinteren Glühfaden, dadurch gekenn- zeichnet, dass dieser Glühfaden um seine lange Achse gedreht angeordnet ist, so dass die optische Achse des Pyrometers die Glühfadenfläche unter einem von einem rechten abweichenden Winkel schneidet. EMI2.3 3. Pyrometer according to claim 1 with a band-shaped rear filament, characterized in that this filament is arranged rotated about its long axis so that the optical axis of the pyrometer intersects the filament surface at an angle deviating from a right angle.
