Sn\u00edma\u010d pr\u00fadu s otvorenou slu\u010dkou s Hallov\u00fdm efektom je typ sn\u00edma\u010da pr\u00fadu, ktor\u00fd priamo meria magnetick\u00e9 pole generovan\u00e9 pr\u00fadom pretekaj\u00facim vodi\u010dom.<\/p>\n

Ako funguje Hallov sn\u00edma\u010d pr\u00fadu s otvorenou slu\u010dkou:<\/h2>\n
    \n
  1. Tok pr\u00fadu:<\/strong> Ke\u010f vodi\u010dom pretek\u00e1 pr\u00fad, vytv\u00e1ra sa okolo neho magnetick\u00e9 pole.<\/li>\n
  2. Detekcia magnetick\u00e9ho po\u013ea:<\/strong> Hallov sn\u00edma\u010d umiestnen\u00fd v bl\u00edzkosti vodi\u010da zis\u0165uje intenzitu tohto magnetick\u00e9ho po\u013ea.<\/li>\n
  3. V\u00fdstupn\u00e9 nap\u00e4tie:<\/strong> Sn\u00edma\u010d s Hallov\u00fdm efektom produkuje v\u00fdstupn\u00e9 nap\u00e4tie, ktor\u00e9 je \u00famern\u00e9 intenzite magnetick\u00e9ho po\u013ea, a teda \u00famern\u00e9 pr\u00fadu pretekaj\u00facemu vodi\u010dom.<\/li>\n<\/ol>\n
