Termometr (termo… \u2014 issiq va metr) \u2014 Trani o’lchash uchun mo’ljallangan asbob. Ishi moddalarning kengayishi, elektr qarshiligi, gaz bosimi va b.ning traga bog’likligiga asoslangan. T.ning suyuklikli, gazli va qarshilikli turlari bor. Ulardan eng soddasi suyuklikli T., asosan, rezervuar, naycha va shkaladan iborat. Rezervuar suyuklik, mas., simob bilan to’ldirilgan bo’ladi. t-ra ortishi bilan rezervuardagi simob kengaya boradi va unga ulangan naycha ichida simob ko’tariladi. t-ra kancha yuqori bo’lsa, simob shuncha kengayadi va naycha bo’ylab u shuncha yuqori ko’tariladi. Mac, -35\u00b0 dan Q750\u00b0 gacha Trani o’lchashda simob (-80\u00b0 dan 170\u00b0 gacha \u2014 etil spirta, -200\u00b0 dan Q20\u00b0 gacha \u2014 pentan, \u2014 20\u00b0 dan Q300\u00b0 gacha \u2014 kerosin) bilan to’ldirilgan T.lar ishlatiladi. Turmushda, tibbiyot va meteorologiyada suyuklikli T. qo’llaniladi. Fan va texnikada -269\u00b0 dan Q1063\u00b0 gacha Trani o’lchashda gazli T. qo’llaniladi. Bu T. gaz (past tralarda geliy, yuqori tralarda esa azot) bilan to’ldirilgan idish, simobli aniq manometr va ularni ulovchi kapillyardan iborat. Bunda t-ra gazning hajmi yoki bosimi o’zgarishi orqali aniqlanadi. Sanoatda -60\u00b0 dan Q550\u00b0 gacha Trani o’lchashda ko’pincha manometrik T.dan foydalaniladi. Bu T. gaz (azot), but (xlorli etil) yoki suyuklik (simob) bilan to’ldirilgan ballon hamda kapillyar va prujinali manometrdan iborat germetik tizimdan iborat. t-ra o’zgarishi bilan tizimdagi bosim o’zgaradi, prujina deformasiyalanadi, natijada mil shkala bo’ylab harakatlanadi. Elektr qarshiligining traga bog’liqligiga asoslangan karshilik T.lari va termoelektr yurituvchi kuchning traga bog’likdigiga asoslangan termoparalar ham fan va texnikada keng qo’llaniladi. Bunday tlar yordamida -200\u00b0 dan Q500\u00b0 gacha Trani o’lchash mumkin.<\/p>\n","protected":false},"excerpt":{"rendered":"
