Mercury thermometer - umsizi ethembekileyo Irreplaceable

thermometer Liquid yasungulwa isikhathi eside futhi kungaba kakade ngokuthi "rarity". Manje kukhona okuningi amadivayisi infrared kanye electronic uyakwazi ukulinganisa izinga lokushisa, kodwa futhi emhlabeni yanamuhla abalandeli yalesi elula, yisikhathi, kodwa ngesikhathi esifanayo okunokwethenjelwa kakhulu sokulinganisa ithuluzi, igama lapho izinga lokushisa mercury ...

Leli thuluzi esisemqoka iyiphi owelapha ngonyaka ukusebenza nonyaka ukuze kuzuze impilo yethu. Futhi akusiyo into edabukisayo, singakwazi ukuletha okwamanje esibi. Lapha ngalesi sikhathi enkundleni futhi iqhawe lethu. Sitshele amagama ambalwa ngaye futhi umlingani wakhe abaseduze wesimanje.

mercury lokushisa

idivayisi ngokwanele ezinembile nezilula ukuze ekulinganiseni izinga lokushisa komzimba. Kuyinto hermetically uphawu ingilazi igabha nge capillary equkethe mercury. It has an isici esithakazelisayo - Ukushisa esiphezulu kukholamu mercury ephawulwe, okuyinto asizi phansi. Ukuze lokhu, lethiwa "esiphezulu". Ukuze "kabusha" kumelwe izikhathi ngamandla eziningana kuphazamise igabha lakhe phansi. Mercury thermometer efanelwa yinhlonipho ngenxa ngokunemba high (ngaphakathi 0.1 degree) izilinganiso, ezibanzi spectrum ukusebenzisa izindlela nempilo angenamkhawulo (ngaphansi kwezimo kwesokudla). eziphansi kanye kalula magciwane nayo ezigqanyisiwe. Ububi iyona fragility kuqhathaniswa okusezingeni eliphezulu nokukala ubude besikhathi. Futhi kusukela mercury ezinesihlungu isetshenziswa njengophawu inkomba lokushisa, lokhu kuchaza lihambisana brittleness okusezingeni eliphezulu akudingekile ukuchaza. Kuleli qophelo, izinga lokushisa mercury kunabayeni nozakwabo yesimanje.

izinga lokushisa electronic

inzwa Ukusetshenziswa-sensitive ebheka izinga lokushisa komzimba. Kulula kakhulu ukusebenzisa. Umphumela uboniswa esifushane uma kuqhathaniswa nesikhathi. Ngokuvamile, idivayisi kuveza ukumeda ezihlukahlukene lokushisa izikali, kodwa indlela kunalokho ezingezwakali futhi, uma kuziwa eziphansi onobuhle, kunzima ukuba zibulale. Amabhethri kudingeka ukushintshwa, futhi idivayisi ayikanye intengo ephansi.

izinga lokushisa kwe-infrared

Ukusebenzisa isimiso ngokuhlaziya umzimba womuntu amaza okushisa, umphumela onikelwa esibukweni ngefomethi ajwayelekile. Ingabe zonke izinzuzo ze-thermometer electronic, Nokho, izinga ukuzimisela iphezulu kakhulu futhi kukhona kungenzeka yokuxhumana isicelo. The kungenzeka yokugcina sibaluleke ngempela uma kuziwa ezinganeni noma iziguli elele. Ngesikhathi esifanayo enezinto eziningi amaphutha ukuthi akunakugwenywa:

• ukunemba okuphezulu;
• Ngeke ukalwe ezindaweni ezithile;
• kudinga Samandla njalo;
• ezinganembile endlebeni izifo noma ukuklabalasa okungokomzwelo;
• zibiza.

Uma abavamile mercury lokushisa, ungathenga kunoma iyiphi ekhemisi, kungcono uthenge electronics ezitolo ezikhethekile. Lokhu kuzokuvumela ukuba uthole mfanelo ukuthi ulindele ukusuka kudivayisi ezinjalo.
