Mitundu 4 ya Zowunikira Kutentha

China OEM Pulse Oxygen Saturation Meter For Sale -  Siemens IBP Cable To B.D Transducer – Medke

Sensa ya kutentha ndi chinthu chodziwika bwino pazida zambiri zothandizira kuyang'anira kutentha kwa ntchito m'mabwalo.Ndiwothandiza pamagwiritsidwe okhudzana ndi kasamalidwe ka mankhwala, zida zamankhwala, magawo opangira chakudya komanso kuwongolera zachilengedwe kwadongosolo la AC.Chipangizo chodziwika bwino ndi thermometer, chomwe chimathandiza kuyeza mwachangu kutentha kwa zakumwa ku zolimba.

Nayi mitundu inayi yodziwika bwino ya masensa kutentha:

Thermocouple

Sensa ya thermocouple ndiyo njira yotchuka kwambiri yoyezera kutentha.Ili ndi maubwino osiyanasiyana, monga odzipangira okha, otsika mtengo komanso olimba kwambiri.Sensa yamtunduwu imagwira ntchito poyesa kusintha komwe kumachitika mu voteji ndikuchita mogwirizana ndi thermo-electric effect.Nthawi zambiri imatetezedwa ndi chitsulo kapena chishango cha ceramic kuti iwonjezere kuthekera kwake kogwira ntchito m'malo ovuta.

Resistor Temperature Detector

Chojambulira kutentha kwa resistor (RTD) chimatha kupereka deta yolondola kwambiri.Sensa yeniyeni imamangidwa muzinthu zingapo zolimba, monga mkuwa, nickel ndi platinamu.Izi zimapangitsa kuti zitheke kugwira ntchito pa kutentha kwakukulu komwe kumatha kusiyana ndi -270 ° C mpaka + 850 ° C. Komanso, mtundu uwu wa sensa uyenera kuphatikizidwa ndi kunja kwa kunja kuti ugwire bwino ntchito zake.

Thermistor

Thermistor ndi mtundu wina wa sensa yomwe ndi yosavuta kugwiritsa ntchito, yosunthika komanso yotsika mtengo.Imakhala ndi mphamvu yosinthira kukana kwake pamene kusintha kwa kutentha kumapezeka.Sensa ya kutenthayi imapangidwa muzinthu za ceramic monga faifi tambala ndi manganese, zomwe zingawasiye pangozi yowonongeka.Chothandiza ndikutha kukhala ndi chidwi chochulukirapo poyerekeza ndi RTD.

Thermometer

Thermometer ndi njira yabwino yoyezera kutentha kwa mpweya, zakumwa kapena zolimba.Imakhala ndi mowa kapena mercury madzi mu chubu lagalasi lomwe limayamba kuchulukira kwambiri kutentha kukayamba kukwera.Chubu chagalasi chomwe chimakhala ndi madziwo chimalembedwa ndi sikelo yoyezetsa kuti iwonetse kukwera kapena kutsika kwa kutentha.Komanso, kutentha kumalembedwa mosavuta mumiyeso ingapo, kuphatikizapo Celsius, Kelvin ndi Fahrenheit.

Ponseponse, pali mitundu ingapo yosiyanasiyana ya masensa amsika pamsika.Ndikofunikira kugwiritsa ntchito sensa yoyenera kuti igwirizane ndi pulogalamuyo chifukwa kulondola kumatha kusiyanasiyana ndi zosankha zosiyanasiyana.Sensa yosankhidwa bwino ingapangitse chipangizo kuti chisagwire bwino chifukwa kutentha kunaloledwa kuwonjezeka popanda chenjezo loyenera.


Mitundu ya 4 Yama Sensor Okhudzana ndi Kutentha:


Tsopano tili ndi gulu lathu lazamalonda, kalembedwe ndi kapangidwe kantchito, akatswiri aukadaulo, ogwira ntchito a QC ndi gulu la phukusi.Tsopano tili ndi machitidwe okhwima oyendetsera dongosolo lililonse.Komanso, antchito athu onse ndi odziwa ntchito yosindikiza kwaGulani Oximeter , Nellcor Spo2 Probe , Nellcor Doc-10 Spo2 Adapter Cable, Tikuganiza motsimikiza kuti tili ndi kuthekera kokwanira kukupatsirani malonda okhutira.Ndikufuna kusonkhanitsa zomwe zili mkati mwanu ndikupanga ubale watsopano wanthawi yayitali.Tonse timalonjeza kuti: Csame kwambiri, mtengo wogulitsa bwino;mtengo wogulitsa weniweni, wabwinoko.
