Monga muyeso kutentha kuposa kutulutsa

kuwerenga kusintha Control kutentha (mwa kulankhula kwina, ndi thermometer) chofunika mu zasayansi kapena mankhwala kafukufuku, kutsatira ndondomeko luso kupanga kapena kukonza mankhwala chitetezo.

M'pake kuganiza kuti luso ntchito yopanga, si abwino ntchito zapakhomo. Kupenda mosamalitsa ndi zipangizo kulola kuchita miyezo m'mikhalidwe yosiyanasiyana.

Kumene, zipangizo ambiri, kulola choyezera kutentha, izo thermometers. Zikuphatikizapo nyengo ndi zasayansi, mankhwala ndi magetsi luso ndi manometer, ndi ma siginalo wapadera. Chiwerengero cha zosintha chimachititsa makumi angapo.

Njira ndi zida kuti adziwe kutentha

thermometers bwino kwa ife - mbali yaing'ono chabe ya zonse zilipo mu zida zathu nthawi kapena zipangizo kuti ntchito mu zochitika komwe mukufuna muyeso kutentha. Khama la zizindikiro matenthedwe akhoza ikuchitika ndi njira zingapo. Mfundo za ntchito lililonse limakhala chizindikiro yeniyeni ndi mankhwala kapena thupi. Malinga imene osiyanasiyana n'kofunika kuti miyezo kutentha, kugwiritsa ntchito zipangizo zosiyanasiyana.

• Anzanga. kusintha ake akulola polojekiti kutentha yofanana mu uthunthu madigiri -160 kuti +60. Zipangizo otchedwa gauges.
• Kulimbikira magetsi. Ndi mfundo za ntchito ya thermometers magetsi michenga yopangira zida zamagetsi ndi kukana kayesedwe. Kusiyana mu kuwerenga zipangizo michenga yopangira zida zamagetsi amalola kuchita miyezo mu osiyanasiyana kuchokera madigiri -90 kuti +180. zipangizo zamagetsi angathe yolanda kwa madigiri -200 kuti +500.
• Zotsatira thermoelectric ndi chuma kutsogolera yovomerezeka kapena apadera thermocouples. zipangizo mtundu kupereka tanthauzo yovomerezeka ya malire a kutentha kwa madigiri -50 kuti +1600. zipangizo apadera lakonzedwa kuti ntchito ndi magawo mkulu yovuta. osiyanasiyana awo ntchito - kuchokera 1300 digiri 2500.
• Matenthedwe kukula. Ntchito thermometers madzi, kulola kudziwa kutentha osiyanasiyana kuchokera -190 kuti +600.
• Matenthedwe cheza. Iwo magwero machitidwe a pyrometers zosiyanasiyana. Malinga mtundu chipangizo, ndi zimasiyanasiyana kutentha osiyanasiyana. chidwi ziperekedwe chakuti zipangizozi ali oyenera okha kuona mkulu kuwerenga positive. Mtundu pyrometer opaleshoni kutentha osiyanasiyana ndi 1400 - 2800 ° C. Zipangizo poizoni Chiwerengerochi adzakhala wofanana 20 - 3000 madigiri. Photovoltaic zipangizo atathana kutentha 600 - 4000, ndipo pyrometers kuwala kuzindikira kuwerenga mkati 700 - madigiri 6000.

Mwachibadwa, funso n'lakuti mmene thupi katundu mpata muyeso wa kutentha mpweya ndi kutentha chitsulo. The gauges maziko kutenga mphamvu ya kuthamanga mpweya kapena madzimadzi pa kutentha zina. Pyrometers ndi imagers choti kuyerekeza kutentha kwa cholinga nkhani pamwamba chachikondi kutentha cheza (pyrometers kusonyeza deta mu mawonekedwe digito, ndi imager zotuluka "chithunzi" cha chinthu ndi kutentha kwake). Ntchito zotsatira thermoelectric ndi ziwembu thermocouple. Mokulira ndi thermocouple ndi chatsekedwa magetsi njira ya ochititsa awiri osiyana. Anasankha zotsatira matenthedwe amachititsa voteji ena. Mfundo zofanana ntchito mu thermometers kukana.

Ambiri, kutentha kuyeza njira akhoza kugawidwa mu kukhudzana ndi sanali nawo. Ambiri thambo Mwachitsanzo kukhudzana njira - mankhwala thermometer, si kukhudzana - ikukhudzana imager.
