I-Hydrometers yeenkuni: ukuhlaziywa kwamanqaku omhle. Indlela yokwenza imitha yomswakama ngemithi ngezandla zakho?

Ukuchonga izinga lokunyusa lomthi, iimitha ezizodwa zomswakama zisetyenzisiweyo. Okwangoku, kukho inaliti, ukuqhagamshelana kunye nokuguqulwa kwe-chip. Kwiiparitha zihluke kakhulu. Nangona kunjalo, akukho baninzi abakhiqizi kwimarike ye-hygrometers. Iinkampani eziphambili zingabonwa ngokukodwa kwi-EMCO kunye ne "Valkom". Kuyafaneleka umyinge wamanzi omncumo omhle kwimarike malunga ne-ruble ye-1500.

Ungakwenza njani wena?

Ukuba kuyimfuneko, unokwenza imitha yomswakama ngemithi ngezandla zakho. Isicwangciso saso siquka inzwa yoluhlobo lweelektri. Kwakhona, ifowuni idinga i-generator compact. Ipharamitha yefomati yokukhawulela kufuneka ingabi ngaphezu kwama-30 MHz. Abafowunelwa kwimodeli eyenziwe yinto efanelekileyo ukukhetha inaliti. Sekunjalo, ukwenza imitha yomswakama ngemithi ngezandla zakho, udinga i-chip yesitishi ezintathu.

Ukuhlala rhoqo kweso sixhobo kufuneka kube kummandla we-3.5 F / m. I-microprocessor yemodeli ikhethiweyo nge-amplifier eshukumisayo. Iingcamango zidla ngokuphindaphindiweyo zihlobo lwe-tubular. Kukulungele ukhethe umgca wokubonisa. Ukuthelekiswa namanqaku okubhala, kulula. Ngokukhawuleza i-electrodes yamanzi amanzi anamandla. Ngaloo ndlela, i-catcher iya kufuna ukusetyenzwa. Ukukhetha okugqibela kumzekelo ngabaxhamli. Kule meko, ungasebenzisa amabhetri omnwe ngokuqhelekileyo.

Qha ga mshelana

Unxibelelwano lweemitha zamanzi ezinkuni zilungele ukusebenza kunye neplywood, kunye neparquet. Ukongeza, kwishishini lokwakha, izixhobo zisetyenziselwa ukucacisa ubuncwane beepaneli. Ukuba sithetha ngeempawu zekhontrakthi, ii-generator kumadivayisi ziphantsi kwexesha elide. Ngokuthe ngqo iiprojekti zifakwe kwifom ye-tubular.

Ukuhlala rhoqo kwimilo yeemitha zamanzi amaninzi akudluli kwi-3 F / m. Ubushushu obuphezulu bomzekelo walolu hlobo luyakwazi ukugcina kuma-40 degrees. Isiboniso sisetyenziswe kokubili njengomgca kunye nombhalo wombhalo. Uninzi olutshintsho luxhotyiswe ngophawu lokushisa. Umsebenzi wokulinganisela ufumanekayo kwiinkcukacha ezininzi. Kuyafaneleka kumyinge weemitha ezinomgangatho ophezulu kumaruble amawaka amabini.

I-needle hydrometer

Iimitha zamanzi ezinobumba ezinokuthi zenziwe ngamatye zisetyenziswe, njengommiselo, kwipine okanye ngesi-spruce. Iisenzi kuzo zonke iinjongo zihlobo lwamadielektri. Ukuba sithetha malunga neerameters, ngoko ukuchaneka komlinganiselo ngokusitshintshile kujikeleza nge-0.2%. Ubuninzi bomswakama weefowuni aludluli kwi-35%. Ubungakanani obuncinane obushushu obuvumelekileyo kumanqaku ngama-0 degrees. Iiprosoftprocessors kumacebo amaninzi asetyenziswa kunye nezixhobo zokukhulisa. Kuyafaneleka ukuba imitha yomswakama ophakathi kwemithi (inaliti) kwindawo ye-ruble 1200.
