 EMI2.5 
 Ampere. Jede Spirale hat einen genau festgesetzten Widerstand von 30 Ohm. Jede Gruppe von 300 Spiralen nimmt daher, wenn sämtliche Spiralen d, g mit der Platte i in Berührung stehen, da sie hiedurch parallel geschaltet sind, 
 EMI2.6 
 Ohm. 



  Da der Widerstand von 300 Spiralen jeder Gruppe also   O'l   Ohm ist, müssen 5'9 Ohm vorgeschaltet werden, um zusammen 6 Ohm zu erhalten, damit jede Gruppe nicht mehr wie 0'3 Ampere abnehmen kann. Dieser Strom verteilt sich auf die 300 parallel geschalteten Spiralen, und da, wie schon vorher gesagt, jede Spirale   0'001 Ampere durchlässt,   jede Spirale aber auch einer Fläche von   0#001   m2 entspricht, so zeigt jedes   0#001   Ampere auch   0#001     m2   Fläche an. 



   Wird das   Messinstrument   n nun so beschrieben, dass es nicht Stromstärken, sondern die diesen entsprechenden Flächen anzeigt, so kann man von dem Instrument sofort den Flächeninhalt des zu messenden Körpers bis auf   0001 m2 genau   ablesen. 



   Die konstruktive Ausführung der beschriebenen Vorrichtung ist selbstverständlich eine beliebige und kann in der verschiedensten Weise durchgeführt werden, z. B. kann die achsiale Bewegung der Körper d auch in umgekehrter Richtung vorgenommen werden, oder kann man dieselben Drehbewegungen ausführen lassen usw., auch kann man die Spiralen in anderer Weise   zum   Kontakt bringen, indem beispielsweise nicht das Nichtleitungsvermögen des zu messenden Gegenstandes zur Verhinderung eines Kontaktes benutzt wird, sondern vielmehr,   indem   ein dauernd bestehender Kontakt durch die Dicke des zu messenden Körpers unterbrochen wird usw. 



   Endlich kann man auch leitende Gegenstände nach der neuen Methode messen, indem man z. B. die Anordnung trifft, dass entweder die leitende Fläche selbst nach der Zahl der von ihr parallel geschalteten Widerstände die Messung bewirkt, oder indem der zu messende Gegenstand die Körper d in irgend einer anderen Weise betätigt.

 EMI2.2
 Ohm. At 1'8 volts, 0'4 ohms must be connected upstream so that the current strength does not exceed
 EMI2.3
 group
 EMI2.4
 Amps. Aui every spiral d, g comes from this
 EMI2.5
 Amp. Each spiral has a precisely defined resistance of 30 ohms. Each group of 300 spirals therefore, when all spirals d, g are in contact with plate i, since they are thereby connected in parallel
 EMI2.6
 Ohm.



  Since the resistance of 300 spirals in each group is O'l ohms, 5'9 ohms must be connected upstream in order to get 6 ohms, so that each group can no longer draw like 0'3 amps. This current is distributed over the 300 parallel-connected spirals, and since, as already mentioned, each spiral allows 0'001 amps, but each spiral also corresponds to an area of 0 # 001 m2, so every 0 # 001 ampere also shows 0 # 001 m2 area.



   If the measuring instrument n is now described in such a way that it does not display current intensities, but rather the areas corresponding to them, the area of the body to be measured can be read immediately from the instrument with an accuracy of up to 0001 m2.



   The structural design of the device described is of course any arbitrary and can be carried out in the most varied of ways, for. B. the axial movement of the body d can also be carried out in the opposite direction, or the same rotational movements can be carried out, etc. Contact is used, but rather by interrupting a permanent contact through the thickness of the body to be measured, etc.



   Finally, one can also measure conductive objects according to the new method. B. the arrangement is that either the conductive surface itself effects the measurement according to the number of resistors connected in parallel by it, or by the object to be measured actuating the body d in some other way.
