Intaneti ammeter ndi manja awo. Intaneti ammeter ndi voltmeter

Amperemeters - ndi zipangizo kuti ntchito kudziwa ziliri pa dera la. Intaneti zosintha anapangidwa pamaziko a comparators lapansi. amasiyana ndi lolondola kayesedwe. M'pofunikanso kukumbukira kuti zipangizo angathe kuikidwa mu dera ndi DC ndi AC.

Mtundu-kuwasiyanitsa chishango, m'manja ndipo anamanga-mu kusinthidwa. Mwa maikidwe ali zimachitika ndi chipangizo gawo-tcheru. Mu gulu osiyana amalembedwa kusankha chitsanzo. Kuti mokwanira kukhala uproarious mu zipangizo ndikofunika kudziwa chipangizo ammeter.

galimoto ammeter

Ochiritsira digito ammeter dera chikuphatikizapo comparator, pamodzi ndi resistors. microcontroller ntchito kwa kutembenuka voteji. Nthawi zambiri izo ntchito ndi diodes pakuyenerera. Stabilizers amene anaika kokha kusankha zosintha. Zosefera burodibandi ntchito ikhale yolondola miyezo. zipangizo gawo zili ndi transceivers.

Chitsanzo manja anu

Sungani ammeter digito ndi manja awo ndi zovuta. Kwenikweni izi Pakufunika ndi comparator Mkhalidwe. tilinazo chizindikiro sayenera zosakwana 2.2 microns. Osachepera kusamvana ziyenera anakhalabe pa 1 MA. The microcontroller mu zida ndi kugwira diodes kutchulidwa. Sonyezani dongosolo olumikizidwa kwa izo mu fyuluta. Komanso kuti kusonkhanitsa digito ammeter ndi manja ake kukhazikitsa resistors.

Nthawi zambiri iwo amasankhidwa oyimba mtundu. Shunt mu nkhani iyi ayenera kuyikidwa kumbuyo comparator lapansi. Division chiŵerengero zimadalira unit transceiver. Ngati ife kulankhula za chitsanzo yosavuta, limagwiritsa ntchito zazikulu mtundu. zipangizo zamakono zili ndi Anzawo kopitilira muyeso-yeniyeni. Zonse gwero panopa akhoza kukhala ochiritsira lifiyamu-ion batire mtundu.

DC chipangizo

Intaneti DC ammeter ndi chikalata pamaziko a comparator tcheru kwambiri. M'pofunikanso kukumbukira kuti stabilizers ndi kuikidwa zipangizo. Resistors ali oyenera okha oyimba-mmwamba mtundu. The microcontroller Pankhaniyi amamasulidwa ku diodes kutchulidwa. Ngati ife kulankhula za magawo, chigamulocho osachepera zipangizo ndi wofanana 1 MA.

zosintha AC

Ammeter (digito) AC zikhoza kuchitidwa paokha. Microcontrollers ntchito zitsanzo ndi rectifiers. Kuti ikhale yolondola muyeso ntchito Zosefera monga burodibandi. Shunt kukana mu nkhani iyi ayenera kukhala osachepera 2 ohms. Tilinazo resistor ndi chofunika kukhala 3 microns. Stabilizers zambiri anaika mtundu kukula. M'pofunikanso kukumbukira kuti kufunika kumanga triode. Izo ziyenera soldered mwachindunji comparator a. Chovomerezeka zolakwa za zipangizo za mtundu uwu ndi kuzungulira 0.2%.

Kugunda kuyeza zida

Kugunda kusinthidwa amakhala ndi owerengera. zitsanzo Current amapangidwa pa maziko a chipangizo atatu zisathe. Resistors akugwiritsidwa kokha orthogonal mtundu. Childs, magawano Chinthu ndi wofanana 0,8 pa iwo. Chovomerezeka zolakwa, nayenso, ndi 0.2%. kudziwa chinyezi wa chilengedwe akhoza zimachitika zolakwa za zipangizo. Iwo saloledwa kuti ntchito pa kutentha subzero. Self-kusonkhana kusinthidwa mabvuto. Transceivers zitsanzo ntchito kokha zazikulu mtundu.

The zida za zosintha gawo-tcheru

Fezi-tcheru zitsanzo ziti zomwe 10 ndi 12 V. The chizindikiro chovomerezeka mphulupulu zitsanzo zikuuluka kuzungulira 0.2%. The owerengera mu zipangizo ntchito kokha mtundu awiri-bit. Microcontrollers ntchito ndi rectifiers. Chinyezi ammeters samuopa mtundu uwu. Ena zosintha ndi amplifiers. Ngati zambiri ndi chipangizo msonkhano, chofunika anazimitsa resistors. A gwero khola la mphamvu mwina ochiritsira lifiyamu-ion batire. The diode mu nkhani iyi si zofunika.

Pamaso khazikitsa ndi microcontroller n'kofunika solder sefa. Converter kwa lifiyamu-ion chofunika variable mtundu. Tilinazo index ndi pa microns 4.5. Ndi lakuthwa voteji dontho mu dera la zifunike resistors. magawano chinthu Pankhaniyi zimadalira bandiwifi wa comparator lapansi. Osachepera kuthamanga zipangizo za mtundu uwu si upambana 45 kPa. Direct panopa kusintha ndondomeko limatenga 230 MS. mlingo wotchi zimatengera mtundu wa kauntala.

Chiwembu zipangizo kusankha

Kusankha digito DC ammeter anapangidwa pamaziko a comparators ndi bandiwifi mkulu. zitsanzo chocheperako zolakwa liri 0,3%. Zipangizo ntchito pa mfundo za-chinthu chimodzi kusakanikirana. Owerengera akugwiritsidwa kokha mtundu awiri-bit. Khola magwero panopa zakonzedwa kuti comparator lapansi.

Resistors oyimba mtundu ntchito. Chifukwa chololera msonkhano zitsanzo amafuna transceivers awiri. The Zosefera Pankhaniyi akhoza amasintha molondola kayesedwe. kuthamanga zipangizo osachepera kuzungulira 23 kPa. Lakuthwa voteji dontho kumachitika kawirikawiri. Shunt kulimbana ndi zambiri zosakwana 2 ohms. Panopa kudziwika pafupipafupi zimadalira comparator lapansi.

Universal zipangizo choyezera

Universal chingwe zamakono zili abwino kwambiri ntchito zapakhomo. Comparators si tilinazo kwambiri nthawi zambiri anaika mu zipangizo. Choncho, zolakwa kololeka kuzungulira 0.5%. Owerengera ntchito atatu manambala mtundu. Resistors ntchito potengera capacitors lapansi. Transistors zopezeka mu gawo ndi mtundu zimachitika.

Chigamulocho pazipita zida si upambana 12 MA. Shunt kukana, monga ulamuliro, ndi m'dera la 3 ohms. Chinyezi zipangizo ndi 7%. Kuthamanga mtheradi Pankhaniyi zimadalira dongosolo chitetezo anaika.

Gulu-wokwera lachitsanzo

Panelboard zosintha anapangidwa pa 10 ndi 15 V. The comparators mu zipangizo anaika ndi rectifiers. Kololeka zolakwa zipangizo si zosakwana 0.4 5.
