Momwe mungayesere sensor ya kutentha ndi multimeter

19.02.2023 /

Ma geji olakwika kapena zoyezera kutentha zimakonda kupereka zotsatira zosaoneka zikagwiritsidwa ntchito, zomwe zimapangitsa kuti pakhale maulendo okwera mtengo opita kumakanika ndi kukonza kosafunikira, kotero kuthetsa mavuto ndikofunikira. Mufunika sensa yowoneka bwino ya kutentha yokhala ndi kalasi yoyamba yolondola.

Choyezera kutentha kapena geji imathandizira kutentha kosasintha kuti injini igwire bwino ntchito.

Kuti ndikuwongolereni momwe mungayang'anire momwe thermometer yanu ilili, ndafotokoza njira zinayi zatsatanetsatane zowonetsetsa kuti thermometer yanu ikugwira ntchito bwino.

Kawirikawiri, kuyang'ana ndi kuthetsa mavuto a kutentha kumaphatikizapo:

1. Kuwunika mawaya ndi zomwe zimafanana

2. Kuyang'ana chizindikiro cha Ohm kuchokera ku Chida Chotumizira

3. Kuyang'ana chizindikiro cha ohm pa kupima kuthamanga ndipo potsiriza

Kuyang'ana pa pressure gauge yokha

Mu bukhuli, tidutsa pamwambazi mwatsatanetsatane.

Mudzafunika zida zotsatirazi:

  • Digital multimeter
  • Kulumikiza mawaya
  • Gwero la Mphamvu (1)
  • kachipangizo kutentha
  • Calculator, cholembera ndi pepala
  • Sender unit
  • Machine

Momwe Mungathetsere Sensor Yolephereka Kapena Yakunja Yachibadwa Ya Kutentha

Tsatirani izi kuti muyese ntchito ya thermometer yanu:

  1. Kuwunika mawaya ndi malo ogwirizana. Ngati mawaya sanalumikizidwe bwino, kapena ngati aphwanyika ndikuduka, sensor ya kutentha sigwira ntchito bwino kapena kusiya kugwira ntchito. Kuti muwone momwe mawaya amayendera, gwirani chiwongolero chimodzi ku waya wapansi ndikulumikiza choyesa china ku mtengo wamagetsi wamawaya (nthaka) kuti multimeter igwire ntchito ngati ammeter. Idzawonetsa zinthu zosiyanasiyana pazenera. Mtengo uyenera kukhala ziro pa waya wokhazikika, apo ayi cholakwika chimachitika.
  2. Kuyang'ana chizindikiro cha ohm chochokera ku transmitter. Nthawi zambiri mwakhala mukukumana ndi vuto lomwe muyenera kusintha gawo la wotumiza la geji yoyezera kutentha m'galimoto yanu. Kuti muyese mtundu wa ohm, muyenera kulumikiza gauge ku multimeter yanu, kuonetsetsa kuti mumagwirizanitsa ma terminals abwino (ie zabwino ku zabwino ndi zoipa kwa zoipa). Onetsetsani kuti mukuwerenga zowerengera m'malo opanda kanthu komanso athunthu kuti mutha kusankha cholumikizira choyenera chagalimoto yanu. Mukalumikiza chowulutsira ku DMM mu ohm setting (mutha kusankha 2000 ohms - mutha kukanda ma terminals a transmitter kuti muwerenge molondola), lembani kukana kapena kuchuluka. Kudziwa kukana kwa sensor yanu kudzakuthandizani kusankha sensor yogwirizana ndi galimoto yanu.
  3. Momwe mungayang'anire chizindikiro cha ohm pa pressure gauge. Kuti muyeze kukana, komwe kumadziwikanso kuti gauge resistance, onetsetsani kuti palibe madzi akuyenda mubokosi lotumiza kapena chinthu china chilichonse chomwe mungafune kuyesa, kenako ikani mapulagi/mapulagi akuda ndi ofiira mu COM ndi omega VΩ motsatana, sinthani multimeter. m'malo okanira olembedwa Ω ndikukhazikitsa kuchuluka kwake. Lumikizani ma probes ku transmitter kapena chipangizo chomwe mukufuna kuyesa (osanyalanyaza polarity popeza kukana sikuli kolowera), sinthani kuchuluka kwa geji ndikupeza mtengo wa OL, womwe nthawi zambiri umakhala 1OL.
  4. Pomaliza, fufuzani sensor. Mutha kuchita izi pochita izi:
  • Chotsani choyezera kutentha kuchokera pagawo lotumizira.
  • Sinthani kiyi (kuyatsa) ku malo "pa".
  • Lumikizani waya wa sensor ya kutentha ku mota pogwiritsa ntchito ma jumper.
  • Onetsetsani kuti muyeso wa kutentha uli pakati pa kuzizira ndi kutentha
  • Sinthani kiyi pamalo olembedwa "Off."
  • Yang'anani ma fuse omwe amawombedwa m'galimoto ndi omwe amalumikizidwa ndi sensa ya kutentha, ndipo m'malo mwawo ngati aphulitsidwa.
  • Gwirani waya (jumper) wolumikizidwa ku terminal ya sensor pafupi ndi mota.
  • Kenako kuyatsa kiyi poyatsira popanda kuyambitsa galimoto. Panthawiyi, ngati kutentha kwa kutentha kukuwonetsa "kutentha", zikutanthauza kuti pali waya wosweka mu chipangizo chotumizira ndipo muyenera kukonza kutentha kwa kutentha.

Kufotokozera mwachidule

Ndikukhulupirira kuti phunziroli lakuthandizani kuti musamapite kumakanika kangapo kuti mukawone kapena kukonza sensa. Mutha kuchita nokha ndikuchepetsa mtengo wagalimoto yanu. (2)

Onani zina mwazolemba zathu pansipa.

  • Momwe mungayang'anire kutuluka kwa batri ndi multimeter
  • Momwe mungayesere kusintha kowala ndi multimeter
  • Momwe mungayesere sensa ya crankshaft yamawaya atatu ndi multimeter
