Resistance position sensor

1.Resistance position sensors, yomwe nthawi zina imatchedwa potentiometers kapena position converters, imaphatikizapo mitundu yozungulira ndi yozungulira. Poyambirira adapangidwa kuti azigwiritsidwa ntchito zankhondo, amagwiritsidwa ntchito kwambiri posinthira mawailesi, ma TV kapena ma control panel.

2.Potentiometer ndi chipangizo chopanda mphamvu ndipo sichifuna mphamvu zowonjezera ndi chithandizo cha dera. Potentiometer ili ndi njira ziwiri zogwirira ntchito: kugawa kwamagetsi ndi kukana kosinthika. Akagwiritsidwa ntchito ngati chotsutsa chosinthika, kukana kwake kumasintha ndi malo otsetsereka, ndipo mapeto okhazikika ndi otsetsereka amagwiritsidwa ntchito pogwira ntchito. Mukagwiritsidwa ntchito pogawa magetsi, ndiye kuti potentiometer imagwiritsidwa ntchito kwambiri.

3.The output reference voltage imapezeka mwa kugawa chinthu chotsutsa. Maonekedwe amtundu wa mapeto otsetsereka angapezeke molingana ndi chiphunzitso cha magawo a voteji a resistor series ndi reverse linanena bungwe voteji. Zimaphatikizanso gawo la amplifier ndi potentiometer position sensor, ndipo mphamvu yotulutsa imawonetsa malo otsetsereka.

4.Nthawi zambiri, potentiometers amagwiritsidwa ntchito ngati masensa a malo. Ili ndi malekezero awiri osasunthika ndi mapeto otsetsereka, ndipo mapeto otsetsereka amagwirizanitsidwa ndi kunja kupyolera mu shaft yotumiza makina. Mtundu woyenda ukhoza kukhala wozungulira kapena wozungulira. Pamene mapeto otsetsereka asuntha, asintha kukana pakati pa malekezero awiri okhazikika. Mphamvu yamagetsi yotulutsa nthawi zambiri imakhala yolingana ndi kusuntha kwa malekezero otsetsereka, kapena kukana kwa malekezero otsetsereka ndi malekezero okhazikika amafanana ndi kusamutsidwa.

5.Potentiometers imabwera mumitundu yambiri ndi mitundu, ndipo awiri omwe amagwiritsidwa ntchito kwambiri ndi ozungulira komanso ozungulira. Ikagwiritsidwa ntchito ngati sensa yamalo, mapeto ake otsetsereka nthawi zambiri amalumikizidwa ndi chinthu chomwe wapezeka. Pogwira ntchito, voteji yokhazikika iyenera kuyikidwa kumapeto kwa potentiometer yokhazikika. Voltage imachokera ku sliding terminal ndi fixed terminal, ndiye kuti, mphamvu yamagetsi imagwirizana ndi malo otsetsereka.
