Abstract

Die Erfindung betrifft eine fernmesstechnische Einrichtung mit einer speisenden Empfangseinrichtung (4) und einer von der Empfangseinrichtung (4) über eine Stromschleife (3) gespeisten Gebereinrichtung (1) zur Ausgabe mindestens eines variablen Messwerts, wobei dem Schleifenstrom der Messwert aufgeprägt ist, mit einem weiteren aus der Stromschleife (3) gespeistes Gerät (2) und Verfahren zu dessen Betriebsspannungsversorgung. Dazu wird vorgeschlagen, das Gerät (2) mit Regelmitteln (11, 12) zur adaptiven Betriebsspannungsanpassung an den Schleifenstrom in Abhängigkeit vom aktuellen Leistungsbedarf auszustatten, die die Betriebsspannung (Uw) bei anwachsendem Schleifenstrom umgekehrt proportional zum Schleifenstrom bis zu einem Minimal-Betriebsspannungswert absenken und die Betriebsspannung (Uw) bei weiterem Anstieg des Schleifenstroms schleifenstromunabhängig konstant halten.
