Trimmer resistor - mumwe chikuru yemagetsi zvinhu

Mumatunhu ano vave nevakawanda kureva siyana okunatsiridza resistors. Huru parameter kwakadaro zvinhu - ichi zvemagetsi nemishonga. The yechipiri zvechadenga zvikamu zvakadai zvingasanganisira vaifanira simba nounzenza uye kukanganisa kuramba Rating. Zvichienderana zvinobvira kuchinja nemishonga, kusiyanisa constants uye variables kwaiita redhiyo zvinoriumba. The mhando chaikosha rokutanga ane dzakananga nemishonga risingagoni kuchinjwa. Uyewo, muenzaniso wakakwana chikamu ichi chechipiri angachinja noruzhinji ichi. Izvi zvikamu kirasi anosanganisira potentiometer, rheostat, shanduka resistor uye kugera. maviri okutanga anowanzodanwa kushandiswa simba zvemagetsi, ekupedzisira zviviri zvinonyanya yaiwanzoshandiswa microelectronic namano.

On namaapuro shanduka uye trimmer akakamurwa provoloochnye uye besprovoloochnye. Zvichienderana sei kurwisa kuchinja tisiyanise muhombe uye mubato.

Chinonyanya nyore kugadzira panguva provoloochnogo resistor. Sezvo nechigadziko, izvozvo anoita somunhu insulating mhete. chaikosha iri muchikuvadza waya, migumo izvo vasiyana 2nd zvakanyanyisa vokukurukura radioelement. Top mubato seti ane mubato (unofanira kukodzera naka kuti mhete) uye pamwechete aine buri kuti pakavha kutenderera sikurudhiraivha. In danho rinotevera kumisa nechepakati vachionana, izvo zvaizoita batanidza pakati nechepakati chinouraya uye maatomu akafanana kutenderera. Kwokupedzisira danho mukugadzira imwe redhiyo akadai trimmer, kunoratidzwa kugadzwa dzakaungana mamiriro ari unodzivirira dzimba. Saka muchidimbu anotarira muzvigadzirwa pachiremera gadzira yenhengo izvi. Kana chinhu iri basa kirasi besprovoloochnyh ipapo kurovha danho ichitenderera waya - chindori anoitwa ane dielectric haachipo, uye kare panguva kamwe kubva kumusoro nemishonga zvinhu (kazhinji - isingawanzowanikwi pasi zvinhu kuva mukuru kwazvo mutengo). Mari mutengo yenhengo yakaitwa nenzira iyi, kupfuura mumutsetse wokutanga, uye nokuda kuti havasati kuchapararira.

Izvi yemagetsi chinhu akawana kushandiswa mukuru gudzazwi mumatanho (wayo yaidzorwa Via fuma). At mazano resistor ravira kugara nemishonga, uye pamusoro mumwe goho - aine shanduka. Mushure kuvhara gungano zano iri vachishandisa okupedzisira chinhu vakasarudzwa achida pfuma chinhu. To ichi Kukosa slots kusvikira kusvikira munhu achida padanho kushanda. Pashure marongero zvakakwana, iyo varnish akashandisa pamusoro (kune resistor). chinoumba Trimmer anogona nokusaziva kutendeuka (kubudikidza kubata, vibration, kuwa) uye zvadaro kugadzirisa zano zvakare. Kuti izvi zvisaitike, uye rinoshandisirwa pamusoro lacquer kuti kugadzira kune kuramba mutengo.

Ona kukosha basa reDare trimmer yazvino microprocessor technology (uye kwete chete), zviri zvakaoma. Asi zvinokuchengetedzai kutaura kuti yakadaro chinoumba redhiyo rinoshandiswa zvinenge zvose zvemagetsi. Uye trimmer ose gore vari kuwana kuwedzera kushanda munyika itsva redunhu mhinduro.
