Abstract
A találmány berendezésre és eljárásra vonatkozik a dielektrokinetikuseffektus változásainak detektálásához egy adott környezetben. Aberendezésben egy adott pillanatban egy pillanatnyi környezetidielektrokinetikus állapotban egy antennával (2) elektromosanösszekötött áramdetektor az antennáról (2) antennajelet vesz azemlített dielektrokinetikus effektus változásainak érzékelésekor. Aberendezés tartalmaz egy olyan alacsony bemeneti áramerősségű erősítőt(12), amelynek 50 Hz-en vagy az alatt működéshez alkalmasfeszültségzaj spektrális sűrűségi görbéje van és össze van kapcsolvaaz antenna (2) jelének vételéhez és az első jel kibocsátásához.Továbbá egy erősítőfokozat (30) van sorosan kötve az alacsony bemenetiáramerősségű erősítőhöz (12) az első jel felerősítéséhez egy olyankimenetijel-szintre, ami alkalmas a dielektrokinetikus effektusváltozásainak detektálásához egy érzékelőkészülékkel. Azerősítőfokozatok (30, 32, 34, 36) tartalmaznak nullázóáramkört (22) akimeneti jel periodikus hitelesítéséhez a pillanatnyilag környeződielektrokinetikus feltételekkel összemérhető előre meghatározottértékre. Az alacsony áramerősségű erősítő (12) olyan műveleti erősítő,amelynek 18 Hz alatt működő feszültség-zaj spektrális sűrűségi görbéjevan. Az erősítősor magában foglal erősítőfokozatokat (30, 32, 34, 36).Az első erősítőfokozat (30) állandósított erősítésű erősítő. A másodikerősítőfokozat (32) változtatható erősítésű erősítő, amelyik a nullázóofszetbeállításától függően változik. A harmadik erősítőfokozat (34)változtatható erősítésű erősítő, amelyik a középszint beállításátólfüggően változik. Ó
