Chowunikira Kutentha kwa Resistance (RTD) Chithunzi Chodziwika

Msonkhano wa Resistance Temperature Detector (RTD)

RTD Assembly ndi sensa yoyezera kutentha yomwe nthawi zambiri imagwiritsidwa ntchito limodzi ndi zida zowonetsera, zojambulira, ndi zida zina. Yapangidwa kuti iyeze kutentha kwa zinthu zosiyanasiyana mkati mwa -200°C mpaka +500°C ndipo imagwiritsidwa ntchito makamaka m'magawo amakampani monga mafuta, mankhwala, ndi mphamvu.

Mitundu ya RTD:PT100, Cu50, Cu100

Chitoliro cha chubu choteteza (mm):φ12，φ16

Zipangizo Zoteteza Chubu:304/310/316L/321 Chitsulo Chosapanga Dzira, Inconel 600

Cholumikizira cha RTD ndi choyezera kutentha kolondola kwambiri. Chinthu chake chodziwira kutentha nthawi zambiri chimapangidwa kuchokera ku zitsulo zoyera kwambiri monga platinamu (Pt) kapena mkuwa (Cu). Ma RTD a Platinamu amapereka kulondola kwakukulu komanso kutentha kosiyanasiyana, koma pamtengo wokwera, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito poyesa kutentha kolondola komanso kotentha kwambiri. Ma RTD a Copper amapereka mzere wabwino kwambiri ndipo ndi otsika mtengo, komabe kuchuluka kwawo koyezera ndi kocheperako (-50°C mpaka +150°C).

Gulu la RTD lomwe lasonkhanitsidwa limapangidwa ndi chinthu chozindikira (platinamu kapena waya wamkuwa), ma lead olumikizira, chubu choteteza, ndi mutu wolumikizira. Mitundu yayikulu ndi magulu a RTD a pulatinamu ndi magulu a RTD amkuwa.

Mfundo Yogwirira Ntchito ya RTDs

RTD (Resistance Temperature Detector) imayesa kutentha pogwiritsa ntchito mphamvu ya magetsi ya chitsulo chowongolera kutentha imasintha ndi kutentha. Kutentha kukasintha, mphamvu ya kukana imawonetsa ubale wogwirizana kwambiri ndi kutentha. Poyesa molondola kukana kumeneku, mphamvu ya kutentha yofanana imatha kudziwika bwino. Mosiyana ndi ma thermocouples, ma RTD safuna kubwezeredwa kwa malo ozizira. Amapereka mphamvu yokhazikika ya chizindikiro komanso kulondola kwambiri, zomwe zimapangitsa kuti akhale oyenera kuyeza kutentha kotsika mpaka kwapakati.

Makhalidwe a RTD

• Kapangidwe kolimba komanso kolimba kwambiri pamakina

• Kukhazikitsa kosavuta komanso kukonza kosavuta

• Kulondola kwambiri pa muyeso komanso kukhazikika bwino

• Kutulutsa chizindikiro chokhazikika komanso mphamvu yolimbana ndi kusokoneza

Kugwiritsa ntchito ma RTD

• Makampani Opanga Mphamvu:Kuyeza kutentha mu ma boiler a power plant, mapaipi a nthunzi, ndi makina otulutsa utsi a turbine.

• Makampani Opanga Mafuta:Kuyang'anira kutentha kwa ma reactor, ng'anjo zosweka, mapaipi, ndi matanki osungiramo zinthu.

• Makampani Opanga Zitsulo:Kuwongolera kutentha mu uvuni wophulika, mastovu otentha, ndi mizere yopanga zitsulo.

• Zipangizo za Makina:Chitetezo chotentha kwambiri cha injini, mabearing, ma gearbox, ndi zina zotero.

• HVAC (Kutenthetsa, Kupumira mpweya, ndi Kuziziritsa Mpweya):Kuyeza kutentha kwa madzi ndi mpweya m'makina oziziritsira mpweya apakati.

• Ma laboratories ndi Kafukufuku wa Sayansi:Mapulogalamu ofunikira kuyeza kutentha kolondola kwambiri komanso kokhazikika.
