Trimmer resistor - daya daga cikin manyan lantarki abubuwa

A zamani haihuwarka an yadu amfani da su daban-daban gyare-gyare resistors. Babban siga irin wannan abubuwa - wannan lantarki juriya. A sakandare halaye na irin wannan sassa iya hada wani matsakaicin ikon masha'a da kuskure juriya rating. Dangane da yiwu canji na juriya, rarrabe constants da canji na da irin wannan rediyo aka gyara. A farko da irin rabi yana da wani takamaiman juriya wanda ba za a iya canja. Bi da bi, na biyu embodiment wannan bangaren na iya canza wannan halayyar. Wannan aji sassa hada da wani potentiometer, rheostat, m resistor da trimming. Biyu na farko ne aka fi amfani da ikon lantarki, da karshen biyu ana fi amfani a microelectronic na'urorin.

A kan wani zane m da trimmer kasu kashi provoloochnye da besprovoloochnye. Ya danganta da yadda da juriya canje-canje rarrabe Rotary da kuma darjewa.

A mafi sauki zane a provoloochnogo resistor. Kamar yadda tushe, shi abubuwa kamar an insulating zobe. Wannan kashi ne rauni waya, da iyakar abin da aka haɗe da 2nd matsananci Lambobin radioelement. Top rike sa tare da darjewa (shi ya kamata shige da zanen goyo ga zobe), kuma Fitted da tsagi for cover juyawa sukudireba. A mataki na gaba kafa tsakiyar lamba, wanda zai gama tsakanin wani tsakiyar m da kuma wani kashi juyawa. A karshe mataki na Manufacturing irin wannan rediyo kamar yadda trimmer, ta ƙunshi a installing da harhada tsarin a wani m gidaje. Saboda haka a takaicce dubi fasaha sarkar na yi daga wadannan aka gyara. Idan abu ne sananne ga aji besprovoloochnyh sa'an nan skipping da mataki na Tuddan waya - zobe da aka sanya na wani dielectric ba, da kuma riga gã su, daga wani babban juriya abu (mafi sau da yawa - a rare duniya abu da ciwon sosai high price). The kudin farashin aka gyara sanya a cikin wannan hanya, fiye da a cikin ta farko harka, da kuma saboda abin da suka yi ba tukuna yadu.

Wannan lantarki abu sami mafi girma amfani a cikin amfilifa, saukarwa (tare da kayyade via riba). A shigar da resistor an saita m juriya, da kuma a kan wani fitarwa - tare da m. Bayan da ƙulli taro makirci ne via na karshe kashi zaba so riba factor. Don wannan kadi Ramin har sai wani so mataki na aiki. Bayan saitin ne cikakke, varnish amfani a kan saman (ga resistor). Trimmer bangaren iya ba da gangan juya (daga touch, vibration, fall) sa'an nan dole daidaita makirci sake. Don kauce wa wannan, kuma yana amfani da saman lacquer domin kayyade da juriya darajar.

Rate muhimmancin irin rawa da trimmer a zamani microprocessor fasahar (kuma ba kawai), shi ne quite wuya. Amma shi ne hadari a ce cewa irin wannan rediyo bangaren da ake amfani a kusan dukkanin na'urorin lantarki. Kuma trimmer a kowace shekara ana samun karuwar aikace-aikace a cikin sabon kewaye mafita.
