Ammeter Digital ngezandla zabo. ammeter Digital voltmeter

Amperemeters - amadivayisi ezisetshenziswa ukucacisa samanje wesifunda. ukulungiswa Digital zenziwa ngesisekelo the comparators. yabo ingafani ukunemba ukulinganisa. Kubalulekile futhi ukuqaphela ukuthi amadivayisi ingafakwa wesifunda DC futhi AC.

isihlangu yohlobo ahlukaniswe kubo, ephathekayo kanye esakhelwe ukuguqulwa. Ngu aphoyintimenti has ishayela nedivayisi isigaba-sensitive. Ngo wodwana ibhalwe imodeli zikhethe. Ukuze ube ngokugcwele uproarious e amadivaysi, kubalulekile ukwazi kudivayisi ammeter.

Ukushayela ammeter

Ezivamile digital ammeter isifunda sihlanganisa iSifundazwe a comparator, kanye resistors. the microcontroller isetshenziselwa voltage ukuguqulwa. Ngokuvamile-ke isetshenziselwa ukubhekisela diodes. Stabilizers efakiwe kuphela ukulungiswa zikhethe. broadband izihlungi zisetshenziselwa ngezelela izilinganiso. amadivaysi Isigaba anemisila transceivers.

Khombisa kusezandleni zakho

Ukuqoqa ammeter digital ngezandla kunzima. Ngokuyinhloko lokhu kuzodinga comparator qualitative. ukuzwela ipharamitha akufanele kube ngaphansi kuka-2.2 microns. lesinqumo ubuncane kumele zigcinwe ngaso 1 ma. I microcontroller e apharathasi isethelwe inkomba diodes. Khombisa uhlelo elixhunywe kuso ngokusebenzisa lemifanekiso. Ngaphezu kwalokho, ukuze ngiqoqele ammeter digital ngezandla zakhe ukufaka resistors.

Ngokuvamile basuke akhethiwe Ukudayela hlobo. Shunt kuleli cala kumele afakwe ngemuva comparator. Division isilinganiso kuncike transceiver iyunithi. Uma sikhuluma imodeli elula, lisebenzisa uhlobo ashukumisayo. amadivaysi Modern anemisila nozakwabo ultra-eqondile. umthombo njalo wamanje kungaba ezivamile-lithium-ion uhlobo ibhethri.

kudivayisi DC

Digital DC ammeter ikhishwa ngesisekelo comparator zibe nezinzwa ezibukhali. Kubalulekile futhi ukuqaphela ukuthi stabilizers ezifakiwe e amadivaysi. Resistors afaneleka kuphela uhlobo yokudayela. I microcontroller kuleli cala isethelwe inkomba diodes. Uma sikhuluma nemingcele, lesinqumo ubuncane amadivaysi ilingana 1 ma.

Ukulungiswa AC

Ammeter (digital) AC kungenziwa ngokuzimela. Microcontrollers asetshenziswa onobuhle rectifiers. Ukuze ngezelela nesilinganiso usebenzise izihlungi ezifana broadband. Ukumelana shunt kulokhu akufanele kube ngaphansi kuka-2 ohms. Ukuzwela kwe-Resistor iyadingeka ukuba 3 microns. Stabilizers ngokuvamile efakwe ukunwetshwa hlobo. Kubalulekile futhi ukuqaphela ukuthi kudingeka kwakhiwe triode. Kufanele soldered ngqo comparator. Iphutha OKUVUMELEKILE amadivayisi yalolu hlobo nxazonke 0.2%.

Pulse yokulinganisa zomculo

Pulse ukuguqulwa ubonakala ngokuba zokubala. onobuhle yamanje ekhiqizwa ngesisekelo kudivayisi enamadijithi amathathu. Resistors asetshenziswa uhlobo orthogonal kuphela. Ngokuvamile, isici division ilingana 0.8 at kubo. Iphutha OKUVUMELEKILE yena, kuyinto 0.2%. kuvelana nomswakama imvelo akunakubangelwa amaphutha amadivaysi. Babuye sinqatshiwe isebenziseke kwamakhaza ashubisa umnkantsha. Self-babuthane ukuguqulwa eziyinkinga. Transceivers onobuhle ukusebenzisa uhlobo ashukumisayo kuphela.

I-apharathasi zokuguqulwa isigaba-sensitive

onobuhle Isigaba-sensitive ziyatholakala 10 no-12 V Umngcele iphutha kuvumelekile onobuhle endiza eduze 0.2%. Izinto zokubala idivayisi kuphela ezimbili-bit hlobo. Microcontrollers Kusetshenziswa rectifiers. Umswakama ammeters asesabi zalolu hlobo. Ezinye ukushintshwa kukhona yokukhulisa umsindo. Uma deal nombuthano kudivayisi, edingekayo resistors esitshalweni. A eqondile amandla kungaba ezivamile lithium-ion. I diode kuleli cala ayidingeki.

Ngaphambi kokufaka microcontroller kubalulekile solder lemifanekiso. Converter for lithium-ion edingekayo uhlobo onhlobonhlobo. Inkomba ukuzwela kuba 4.5 microns. Ehlome voltage iconsi yesifunda kufanele resistors ihlolwe. isici ukuhlukana Kulokhu incike bandwidth we comparator. ingcindezi amadivayisi Ubuncane lolu hlobo ingeqi 45 KPA. Direct zamanje ukuguqulwa nqubo ithatha ms mayelana 230. iwashi izinga incike izinga counter.

Isikimu amadivayisi abakhethayo

Okukhethwayo digital DC ammeter senziwa ngesisekelo comparators ne-bandwidth okusezingeni eliphezulu. Iphutha kuyabekezeleleka onobuhle kulingana 0.3%. Amadivayisi ukusebenza isimiso esisodwa-step ukuhlanganiswa. Ibali asetshenziswa kuphela ezimbili-bit hlobo. imithombo Esitebeleni kwamanje ngawengubo comparator.

Resistors ukudayela uhlobo esetshenziswa. Self-inhlangano onobuhle adinga ama-transceivers ezimbili. Izihlungi kulesi simo kungaba ngcono kakhulu ukunemba ukulinganisa. ingcindezi amadivayisi bungu emhlabeni 23 KPA. I abukhali voltage iconsi kwenzeka akuvamile. Ukumelana shunt ngokuvamile esingaphansi 2 ohms. Lamanje ukuthola imvamisa incike comparator.

amadivaysi wokulinganisa Universal

amadivaysi wokulinganisa Universal maningi ezifanele ukusetshenziswa yasendlini. Comparators kungukuthi ukuzwela okukhulu zivame ukufakwa amadivaysi. Ngakho, iphutha ovumelekile nxazonke 0.5%. Ibali asetshenziswa enamadijithi amathathu-hlobo. Resistors asetshenziswa esekelwe capacitors. Transistors sitholakala kokubili isigaba futhi uhlobo ishayela.

Ukulungiswa esiphezulu kwezinsimbi zomculo ingeqi 12 ma. Ukumelana shunt, njengoba umthetho, kuba esifundeni 3 ohms. amadivaysi Ukuswakama 7%. Ingcindezi oyinhloko kulesi simo incike olufakiwe Uhlelo lokuvikela.

imodeli Panel-agibele amahhashi

Panelboard ukulungiswa zenziwa ku 10 kanye 15 V. Le comparators Amadivayisi efakwe nge rectifiers. amadivaysi iphutha Allowable akuyona esingaphansi 0.4 5. Kudivayisi ingcindezi Ubuncane lilingana cishe 10 KPA. Converters asetshenziswa ikakhulu AC hlobo. Self inhlangano yabantwana bakwa-apharathasi ngeke akwenze ngaphandle ezimbili-bit esiphikisayo. I resistors kulokhu asethwe nge stabilizers.

ukuguqulwa Embedded

Embedded ammeter digital ikhishwa ngesisekelo isithenjwa comparator. Umthamo we onobuhle babe kahle eliphezulu, futhi ohlangothini iphutha ecishe ilingane 0.2%.

Microcontrollers avame ukusetshenziswa ngaphandle rectifiers. Isilinganiso samanje inqubo ukuguqulwa ingeqi ms 140.

onobuhle DMK

ammeters Digital voltmeters wale nkampani zihamba phambili. Ububanzi ngokuqinile sesinesethi onobuhle umile. Uma sicabangela voltmeters, bakwazi ukumelana ingcindezi esiphezulu 35 psi. Kulokhu, a transistors toroidal-hlobo asetshenziselwa.

Microcontrollers ngokuvamile efakwe nge inverters. Ukuze laboratory ukuhlolwa apharathasi yalolu hlobo Lifanele. ammeters Digital voltmeters wale nkampani zenziwa nge ezivalekile evikelwe.

Idivayisi Toreh

Wathi ammeter (digital) kukhiqizwa kusuka okusezingeni eliphezulu conductivity zamanje. Ingcindezi enkulu kule divayisi igcina 80 KPA. Okuncane lokushisa kuvunyelwe we ammeter kulingana degrees -10. Wathi umswakama kudivayisi wokulinganisa akesabi. Kunconywa ukuyifaka eduze umthombo wamandla. division isilinganiso ilingana 0.8 kuphela. Ubuningi ingcindezi ammeter (digital) umelana 12 KPA. ukusetshenziswa yamanje zedivayisi imayelana 0.6 A. Transistor isebenzisa isigaba hlobo. Ukuze isetshenziswe ekhaya, lokhu ukuguqulwa kufanelekile.

I Lovat kudivayisi

Wathi ammeter (digital) senziwa ngesisekelo ezimbili-bit esiphikisayo. I conductivity imodeli lwamanje elilingana microns 2.2 kuphela. Nokho, kubalulekile ukuphawula ukuzwela eziphakeme comparator. Uhlelo lusebenzisa inkomba elula futhi usebenzise ucingo lwakho sisekhaya. Resistors wamanje imitha (digital) isethi Ukudayela hlobo.

Kubalulekile futhi ukwazi ukuthi bayakwazi ukumelana imithwalo esindayo. Ukumelana shunt kulokhu akuyona ezingaphezu kwezingu-3 ohms. Yamanje inqubo ukuguqulwa okwenzeka ngokushesha ngokwanele. A ebukhali voltage iconsi kungenzeka ukuthi umataniswe kuphela ukuhlukumeza umbuso lokushisa zedivayisi. Operating Umswakama wathi ammeter ilingana kakhulu ngendlela 70%. Futhi, sokulungiswa okukhulu 10 ma.

imodeli DigiTOP

Lokhu voltmeter digital, ammeter DC ngepayipi isithenjwa diodes. Counter enikeziwe therein ezimbili-bit hlobo. I conductivity we comparator isezingeni emhlabeni 3.5 microns. I microcontroller isetshenziswa ne rectifier. ukuzwela zamanje ukuthi unesikhathi kuhle okusezingeni eliphezulu. Amandla kagesi uba ibhethri ezivamile.

Resistors asetshenziswa uhlobo yomculo Ukudayela. I isimame kuleli cala singanikezwanga. I Transistor has eyodwa kuphela. Direct ukuguqulwa zamanje pretty ngokushesha. Ukuze isetshenziswe ekhaya, kule divayisi awunankinga. Izihlungi anikezwa ngezelela nesilinganiso.
