  Strahlungspyrometer. 
 EMI1.1 
 
Gemäss der vorliegenden Erfindung wird diese Schwierigkeit behohen durch Anordnung einer einstellbaren Blende zwischen der Wärmequelle und dem Thermoelement zur Regelung des auf die Löt- stelle fallenden Strahlenkegels : Vorzugsweise wird zu diesem Zwecke im Pyrometer eine Blende mit
Zentralöffnung verschiebbar angeordnet. Man könnte denselben Zweck aber auch eneichen mit eine feststehend im Pyrometerrohr vorgesehenen Blende mit einstellbarer Strahlendurchgangsöffnung. 



   Die Zeichnung veranschaulicht ein   Ausführungsbeispiel   des neuen Strahlungspyrometers. 



  Mit   r ist   das Pyrometerrohr bezeichnet, in dem das Thermoelement   t   angeordnet ist und das an einem Ende das Okular o und am andern Ende ein Objektiv l trägt. Im Inneren des Pyrometerrohres befindet sich ausserdem erfindungsgemäss eine in einer   Rohrfassung   sitzende Blende b, die in Richtung der Rohrachse verschiebbar angeordnet ist. 



   Mit dem Okular o kann man das Pyrometerrohr auf den Körper, dessen Temperatur gemessen werden soll, lichten. Bei der Justierung wird   zunächst   unter Blenden mit verschieden   grosser   Mittel- öffnung die am besten geeignete ausgewählt, worauf die Feinjustierung durch Verschieben dieser Blende im Rohr erfolgt. 



   PATENT-ANSPRÜCHE :
1. Strahlungspyrometer mit Thermoelement, gekennzeichnet durch eine im   Pyrometerrohr   ange- ordnete einstellbare Blende zur Regelung des auf die warme Lötstelle fallenden Lichtkegels.

  Radiation pyrometer.
 EMI1.1
 
According to the present invention, this difficulty is overcome by arranging an adjustable diaphragm between the heat source and the thermocouple to regulate the beam cone falling on the solder joint
Central opening arranged displaceably. However, the same purpose could also be achieved with a fixed aperture in the pyrometer tube with an adjustable beam passage opening.



   The drawing illustrates an embodiment of the new radiation pyrometer.



  The pyrometer tube r is denoted in which the thermocouple t is arranged and which carries the eyepiece o at one end and an objective l at the other end. In the interior of the pyrometer tube there is also, according to the invention, a diaphragm b which is seated in a tube socket and which is arranged to be displaceable in the direction of the tube axis.



   With the eyepiece o you can light the pyrometer tube onto the body whose temperature is to be measured. During the adjustment, the most suitable one is selected from diaphragms with differently sized central openings, after which the fine adjustment is made by moving this diaphragm in the tube.



   PATENT CLAIMS:
1. Radiation pyrometer with thermocouple, characterized by an adjustable diaphragm arranged in the pyrometer tube to regulate the light cone falling on the warm solder joint.
