Ammeter Digital ngezandla zabo. ammeter Digital kunye voltmeter

Amperemeters - zizixhobo ukuba zisetyenziswa ukugqiba ngoku kwisekethe. Digital iinguqulelo zenziwa ngokwesiseko comparators. ahluke ukuchana yomlinganiselo. Kubalulekile ukuba uqaphele ukuba zingaba kufakelwa ejikeleza kunye DC ne AC.

isihlangu Uhlobo-zizakubalulwa, nezitulo eyakhelwe-ngaphakathi ukulungiswa. Ngesivumelwano iye ukubetha kwentliziyo isixhobo phase-onovakalelo. Xa uhlobo eyahlukileyo ziphawulwe imodeli uyakhetha. Ukuze ube ngokupheleleyo ngakumbi uproarious ngamayelenqe, kubalulekile ukwazi isixhobo ammeter.

ammeter Driving

EziQhelekileyo circuit ammeter wedijithali iquka comparator, kunye resistors. i microcontroller sisetyenziselwa ukuguqulwa ombane. Amaninzi asisetyenziswa ukubhekisela ilight. Ekwenzeni zifakwa kuphela nokulungalungiswa uyakhetha. amacebo broadband asetyenziswa ukwandisa ukuchaneka imilinganiselo. izixhobo Phase kwafakwa transceiver.

Khombisa izandla zakho

Qokelela ammeter yedijithali ngezandla zabo kunzima. Ubukhulu becala oku kuya kufuna comparator qualitative. ubuntununtunu parameter ayinakuba ngaphantsi kwe 2.2 microns. Ubuncinane isigqibo kufuneka igcinwe 1 Ma. Le microcontroller kwi izixhobo umiselwe ukuya ilight reference. bonisa elidityaniswe kuyo ngokusebenzisa lokucoca ulwelo. Ngaphezu koko, ukuze ukuqokelela ammeter yedijithali ngezandla zakhe ukufaka resistors.

Amaninzi zikhetwa uhlobo socofo. Shunt kule meko kufuneka zibekwe emva comparator. Division ratio kuxhomekeke iyunithi transceiver. Xa sincokola ngayo imodeli elula, isebenzisa uhlobo olutshintshayo. izixhobo Modern zixhotyiswe kunye nabo ultra-ngqo. umthombo njalo langoku uhlobo ibhetri lwe Lithium-ion oluqhelekileyo.

device DC

Digital DC ammeter ikhutshwa ngokusekelwe comparator olubuthathaka kakhulu. Kubalulekile ukuba uqaphele ukuba ekwenzeni zifakelwe ngamayelenqe. Resistors kuphela uhlobo efanelekileyo yodayalo ye-EGPRS. Le microcontroller kule meko umiselwe ukuya ilight reference. Ukuba uthethe parameters, isisombululo ubuncinane yamacebo ilingana no-1 Ma.

ukulungisa AC

Ammeter (digital) AC kungenziwa ngokuzimeleyo. Microcontrollers zisetyenziswa onobuhle rectifiers. Ukwandisa ngokuchaneka zomlinganiselo Faka Amacebo okucoca ezifana lwebhendi ebanzi. kufuneka ibe ngaphantsi kwe ohms 2 uxhathiso Shunt kule meko. Uvakalelo resistor kufuneka ukuba microns 3. Ekwenzeni ngokuqhelekileyo efakiweyo uhlobo ukwanda. Kubalulekile ukuba uqaphele ukuba imfuneko yokwakha triode. Kufuneka soldered ngqo comparator. Imposiso kuvumelekile na iingcinga olu hlobo ngeenxa 0.2%.

izixhobo zokulinganisela Pulse

Pulse yokuphila ubonakala ngokuba zokubala. imifuziselo yangoku zenziwa ngokusekelwe isixhobo ngemivo emithathu. Resistors zisetyenziswa kuphela uhlobo orthogonal. Ngokuqhelekileyo, umba ukwahlula ilingana 0.8 kubo. Imposiso kuvumelekile, ke, yi 0.2%. uvakalelo ukufuma yokusingqongileyo ekunokuthiwa iintsilelo izixhobo. Kananjalo uvunyelwe ukusebenzisa kwi ziingqele. Self-ndawonye ukuguqulwa eziyingxaki. imifuziselo transceiver isicelo uhlobo kuphela linamandla.

Izixhobo zokuguqulwa phase-onovakalelo

Imifuziselo Isigaba-onovakalelo ziyafumaneka ukuze V. 10 no 12 parameter Imposiso kuvumelekile njengezibonelo besixhathise kwi 0.2%. Izinto zokubala kule izixhobo ezisetyenzisiweyo kuphela uhlobo bit-mbini. Microcontrollers zisetyenziswa kunye rectifiers. ammeters ukufuma ningoyiki yale hlobo. Ezinye iinguqulelo are yokukhulisa. Ukuba isivumelwano kunye nebandla isixhobo rhoqo, ngoko resistors watshintshela efunekayo. Umthombo ezinzileyo amandla kusenokuba yinto eqhelekileyo lwe Lithium-ion ibhetri. Le diode kule meko akufuneki.

Ngaphambi kokufaka microcontroller kubalulekile ukuba solder lokucoca ulwelo. Converter for lwe Lithium-ion ezifunekayo uhlobo bume. Isalathisi uvakalelo ngayo kwi 4.5 microns. Nge elibukhali drop ombane kwisekethe kufuneka ihlolwe resistors. umba ukwahlukana kulo mzekelo kuxhomekeke bandwidth le comparator. Ubuncinane izixhobo yengcinezelo olu hlobo ayidluli 45 kPa. Direct inkqubo yotshintsho yangoku ithatha malunga 230 ms. izinga clock kuxhomekeka kumgangatho ekhawuntarini.

Scheme Izixhobo uyakhetha

Uyakhetha yedijithali DC ammeter senziwa sisiseko comparators kunye ekwiqondo eliphezulu. Imifuziselo Imposiso ngcono ilingana no 0.3%. Devices ukusebenza kumgaqo ngokunxulumanisa-inyathelo elinye. Zokubala zisetyenziswa kuphela uhlobo bit-mbini. ke imithombo Esitalini yangoku ezimiselwe comparator.

Resistors yokudayala uhlobo kusetyenziswa. Kuba self-indibano imifuziselo zifuna transceiver ezimbini. Lokucoca ulwelo kulo mzekelo unako ukuphucula kakhulu ukuchana womlinganiselo. izixhobo uxinzelelo Ubuncinane ngeenxa 23 kPa. Ukuhla ombane ezibukhali kwenzeka kunqabile. ukumelana Shunt idla ohms ngaphantsi kwe-2. Amaza ubhaqo ngoku lixhomekeke comparator.

izixhobo Universal yokulinganisa

izixhobo Universal yokukala alungele ukusetyenziswa ekhaya. Comparators Akukho ngovakalelo olukhulu badla efakwe ngamayelenqe. Ngoko ke, impazamo avumelekile ngeenxa 0.5%. Zokubala zisetyenziswa uhlobo ngemivo emithathu. Resistors zisetyenziswa zisekelwe phezu capacitors. Transistors afumaneka zombini isigaba kunye nohlobo ukubetha.

Isisombululo iphezulu izixhobo ayidluli 12 Ma. ukumelana Shunt, njengoko umthetho, oko kummandla ohms-3. izixhobo ukufuma yi-7%. Uxinzelelo ekugqibeleni kulo mzekelo kuxhomekeke kwinkqubo yokhuseleko oomatshini.

imodeli Panel-imvelaphi inyuselwa khona

iinguqulelo kancinane Panelboard zenziwa 10 no-15 V. Le comparators ngamayelenqe ezifakwe kunye rectifiers. izixhobo imposiso avumelekile ayikho ngaphantsi kwe 0.4 5. Icebo Minimum xi ilingana malunga 10 kPa. Converters zisetyenziswa ubukhulu becala AC uhlobo. Kuba self ibandla izixhobo akakwazi ukwenza ngaphandle bit-ezimbini ekhawuntareni. Le resistors kule meko zibekwe kunye ekwenzeni.

ukuguqulwa eveze

Iklip ammeter yedijithali ikhutshwa ngokusekelwe kwi reference comparator. Umthamo we beye ngokungenamkhethe phezulu, kunye nayo imposiso silingana malunga 0.2%.
