Description
Direkt anzeigender Gleichspannungsmesser
Die Erfindung betrifft einen Gleichspannungsmesser, der mit einer extrem niedrigen Leistung den Vorteil verbindet, dass er ein direkt anzeigender Spannungsmesser ist, d. h., dass er keinen Verstärker braucht, d.h. also, keine fremde Energiequelle benötigt und dass er ausserdem eine bessere Genauigkeit aufweist, als die bekannten elektrostatischen Instrumente.The invention relates to a DC voltmeter with a extremely low power combines the advantage of having a direct reading Is a voltmeter, d. i.e. that he does not need an amplifier, i.e. therefore, none requires an external energy source and that it also has a better accuracy, than the well-known electrostatic instruments.
Vor allem beginnt auch der Anzeigebereich des Gleichspannungsmesser bei einem niedrigeren Wert, als bei einem elektrostatischen Instrument erreichbar ist.Above all, the display area of the DC voltmeter begins at a lower value than achievable with an electrostatic instrument is.
Der neue Gleichspannungsmesser hat ein Spannband-Drehspul-Messwerk
und seine Vorwiderstände sind aus Drahtwiderständen
Für die kleinste Spannungsstufe wird zweckmässig ein Drahtwiderstand
verwendet, der den Messwerkwiderstand auf die Wideratandshohe von 1 M.@./V. ergänzt.
In Fig. 1 ist die Vorderansicht des Gerätes gezeigt, an welcher nur
die Anordnung der sieben Anschlussklemmen auf einer Plexiglasscheibe 1 auf dem Deckel
des Gehäuses bemerkenswert ist. Das dargestellte Gerät ist ein Instrument, welches
in liegender Anordnung (senkrechte : Spannbandlage)
