Abstract

Způsob měření příčných geometrických parametrů textilních vlákenných útvarů tvaru plochého pásku kapacitním senzorem, u něhož textilní vlákenný útvar prochází měřicí štěrbinou v deskovém kondenzátoru, přičemž textilní vlákenný útvar prochází měřicí štěrbinou prvního deskového kondenzátoru a následně měřicí štěrbinou druhého deskového kondenzátoru, přičemž v každém deskovém kondenzátoru je měřena kapacita, která je pomocí RC obvodu převedena na impulz šířky ԏM a porovnána s nastavitelným impulzem šířky ԏK generovaným kompenzačním generátorem, která odpovídá šířce impulzu generovaného deskovým kondenzátorem bez textilního vlákenného útvaru, a za časový rozdíl impulzů šířky Δԏ mezi impulzem RC obvodu a impulzem kompenzačního generátoru je čítačem čítajícím impulzy z pomocného oscilátoru převeden na počet impulzů p a informace o počtu impulzů p1, p2 každého z obou čítačů jsou odeslány do vyhodnocovacího obvodu pro výpočet geometrických parametrů textilního vlákenného útvaru. Kapacitní senzor pro toto měření.
