PT1000 Yesani Zida Platinum Resistance Temperature Sensor

PT1000 Yezerani Zida Platinum Resistance Temperature Sensor Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Mankhwalawa amapangidwa ndi jekeseni kuyambira koyambira mpaka kumapeto tokha. RTDS ndi masensa olondola kwambiri komanso okhazikika a kutentha, ndipo mzere wawo ndi wabwino kuposa ma thermocouples ndi ma thermistors. Komabe, ma RTD nawonso ndi masensa otsika kwambiri komanso okwera mtengo kwambiri. Chifukwa chake ma RTD ndioyenera kugwiritsa ntchito pomwe kulondola kuli kofunikira komanso kuthamanga ndi mtengo sizofunikira.

Platinum Resistance Temperature Sensors

Mofanana ndi ma thermistors, masensa a kutentha kwa platinamu (RTDs) ndi zoletsa kutentha zomwe zimapangidwa ndi platinamu.

Masensa a kutentha kwa platinamu amagwiritsa ntchito mawonekedwe a chitsulo cha platinamu kuyeza kutentha posintha mtengo wake wokana kutentha kukasintha, ndipo chida chowonetsera chidzawonetsa kutentha komwe kumayenderana ndi kukana kwa kukana kwa platinamu. Pakakhala kutentha mu sing'anga yoyezera, kutentha kwake kumakhala kutentha kwapakati pa gawo lapakati mkati mwa gawo la zomverera.

Kukana kwa platinamu kumatha kugawidwa mu kutentha kopitilira muyeso, kutentha pang'ono, kutentha kwapakati komanso kutentha kwakukulu molingana ndi kuchuluka kwa kutentha, komwe
Kutentha kotsika kwambiri: -196 ° C mpaka +150 ° C,
kutentha kwapansi: -50 ° C mpaka +400 ° C,
kutentha kwapakati: -70 ° C mpaka +500 ° C, ndi
kutentha kwakukulu kungagwiritsidwe ntchito poyeza kutentha mpaka 850 ° C.

Zolemba za Platinum Resistance Temperature Sensor

Thin-film RTD platinamu kukana zinthu zimadziwika ndi kulondola kwambiri, kukhazikika kwapamwamba, ndi kuyankha mwachangu, ndipo nthawi zambiri amagwiritsidwa ntchito popanga zida, zida zamankhwala, ndi zida zama mankhwala. Zotsutsa za platinamu zimakhala ndi mgwirizano pakati pa mtengo wokana ndi kutentha.

Masensa a Platinamu amakhala okhazikika kwanthawi yayitali, okhala ndi data yoyesera ya maola 300 pa 400 ° C komanso kutentha kwambiri kwa 0.02 ° C pa 0 ° C.

TheAmwayisya PT100, PT200, PT1000 Platinum Kutentha Sensor kwaYesani Zida

Mtengo wapamwamba wotsutsa: kukana kwa pt100 kukana kwa platinamu ndi 100 ohms pa 0, ndipo kukana kwa pt1000 kukana kwa platinamu ndi 1000 ohms. Kukana kwa kukana kwa platinamu kumachepa pang'onopang'ono ndi kuwonjezeka kwa kutentha, kotero ndikoyenera ngati gawo lalikulu la chida cha kutentha.

Mkulu tilinazo: Imatha kuyankha mwachangu kusintha kwa kutentha kozungulira, ndipo nthawi yake yofananira ndi 0.15s yokha m'madzi oyenda pang'onopang'ono.

Kukula kochepa: yaying'ono kwambiri, pa dongosolo la millimeters, choncho makamaka yoyenera kuyika m'malo okhala ndi malo ochepa, monga zida za kutentha. Chida cha kutentha palokha ndi chaching'ono, ndipo filimu yopyapyala ya platinamu resistor ndi yoyenera kwambiri.

Kukhazikika kwabwino: Ziwerengero zimasonyezanso kuti zotsutsa za platinamu zimagwira ntchito mosalekeza pa 600 kwa maola oposa 1000, ndipo kusintha kwa kukana kumakhala kochepa kuposa 0.02%.

Mtengo wotsika: Mtengo ndi wotsika pansi pakupanga misa, yomwe ndi 50% -60% yotsika kuposa ma wirewound resistors ofanana.
