EPRO PR9376/20 Hall Effect Speed/Proximity Sensor

EPRO PR9376/20 Hall Effect Speed/Proximity Sensor

Masensa osalumikizana ndi Hall omwe amapangidwira kuti azitha kuyeza liwiro kapena kuyandikira pakugwiritsa ntchito makina a turbomachinery monga nthunzi, gasi ndi ma hydraulic turbines, compressor, mapampu ndi mafani.

Mfundo yogwira ntchito:
Mutu wa PR 9376 ndi sensor yosiyanitsa yomwe ili ndi theka-mlatho ndi zinthu ziwiri za Hall effect sensor. Magetsi aku Hall amakulitsidwa nthawi zambiri pogwiritsa ntchito cholumikizira cholumikizira. Kukonzekera kwa magetsi a Hall kumachitika pa digito mu DSP. Mu DSP iyi, kusiyana kwa magetsi aku Hall kumatsimikiziridwa ndikufanizidwa ndi mtengo wofotokozera. Chotsatira cha kufananitsa chimapezeka pamtundu wa push-pull womwe ndi umboni wafupipafupi kwa nthawi yochepa (max. 20 masekondi).

Ngati chizindikiro cha maginito chofewa kapena chachitsulo chimayenda molunjika (monga mopingasa) kupita ku sensa, mphamvu ya maginito ya sensa imasokonezedwa, zomwe zimakhudza kutsika kwa milingo ya Hall ndi kusintha kwa chizindikiro. Chizindikiro chotuluka chimakhala chokwera kapena chotsika mpaka m'mphepete mwachizindikirocho chimapangitsa kuti theka la mlatho udulidwe mbali ina. Chizindikiro chotulutsa ndi mphamvu yamagetsi yokwera kwambiri.

Capacitive coupling ya zamagetsi kotero ndizotheka ngakhale pamayendedwe otsika kwambiri.

Zamagetsi zapamwamba kwambiri, zosindikizidwa bwino m'nyumba yazitsulo zosapanga dzimbiri komanso zingwe zolumikizira zotchingidwa ndi Teflon (ndipo, ngati zingafunike, zokhala ndi machubu oteteza zitsulo), zimawonetsetsa kuti zikugwira ntchito motetezeka ngakhale m'malo ovuta a mafakitale.
