Momwe mungasankhire sensa yotsika kwambiri ya kutentha

Zofunikira zazikulu za sensor yotentha yotsika kwambiri:

Thekafukufuku kutentha utenga Pt100 kapena PT1000 platinamu kukana, yomwe imakhala yolondola kwambiri komanso yokhazikika bwino. Itha kuyika ma transmitter mu imodzi, mawonekedwe ophatikizika, kukhazikitsa kosavuta, kulondola kwambiri, kugwiritsa ntchito mphamvu zochepa, kutulutsa kosinthika 4-20mA, 0-5V, 0-10V, RS485 ndi ma sign ena. Mtundu waposachedwa ndi woyenera kutumizira mtunda wautali, kapangidwe ka anti-electromagnetic interference circuit, kuwonetsetsa kuti transmitter imatha kugwira ntchito motetezeka komanso modalirika pamavuto osiyanasiyana, ndipo ndiyoyenera kuipitsidwa ndi ma elekitiroma amakono. Ntchito yonse yosindikiza ndi yabwino kutentha osiyanasiyana ndi kukula kwa mawonekedwe akhoza kuyitanitsa malinga ndi zofunikira zapakhomo, zosinthika komanso zosavuta, kapangidwe kazinthu kamangidwe kabwino, mawonekedwe olumikizirana ndi osinthika komanso osavuta, ang'onoang'ono, kulemera kwake, kuyika mopanda pake, zida zoteteza zipolopolo. mitundu yosiyanasiyana (304 zitsulo zosapanga dzimbiri, 316 zitsulo zosapanga dzimbiri, 316L zitsulo zosapanga dzimbiri, ndi zina zotero, zapadera zimatha kusinthidwa malinga ndi zofunikira), Zokwanira muyeso wosiyanasiyana wa media, ulusi wokhazikika wa chitoliro.

Zizindikiro zazikulu zaukadaulo zaumisiri zotsika kwambiri:

Kutentha kosiyanasiyana: mpaka -200 ° C

Chizindikiro chotulutsa: 4-20mA, 0-5V, 0-10V, chizindikiro cha RS485

Katundu kukana: ≤500Ω

Mphamvu yamagetsi: 24VDC

Kugwiritsa ntchito mphamvu: ≤1W

Cholakwika chachikulu: 0.2% -0.5% FS

Kugwiritsa ntchito kwaultra-low kutentha sensor: chimagwiritsidwa ntchito firiji uinjiniya, zasayansi, uinjiniya matenthedwe, mphamvu, chakudya, mankhwala, petrochemical ndi mafakitale ena ndondomeko ndi uvuni, pulasitiki CHIKWANGWANI mankhwala, mayunitsi refrigeration ndi zina lalikulu makina makina kutentha kuyeza.

Kusankha kwa parameter kwa sensor yotentha yotsika:

Mtundu wa chinthu choyezera kutentha: pt100 imodzi, pt1000 imodzi, pt100 iwiri, pt1000 iwiri, ndi zina.

Kusankha molondola: 2B ±0.6°C, B ±0.3°C, A ±0.15°C.

Kutentha osiyanasiyana: -200 ~ 300 ° C.

Njira yolumikizira: mizere iwiri; Waya atatu; Mizere inayi.

Kuteteza chubu awiri: zitsulo zosapanga dzimbiri, 3mm, 4mm, 5mm, 6mm, 8mm, etc. (akhoza makonda malinga ndi zofunika)

Kuteteza chubu kutalika: 20mm, 50mm, 120mm, 150mm, 200mm, etc. (akhoza makonda malinga ndi zofunika)

Kuyika njira: Mu mzere, ulusi phiri M10 * 1, M16 * 1.5, G1/4, G1/2, M20 * 1.5 (akhoza makonda)

Nthawi yoyankha: T0.9S za 6s, pamene liwiro la madzi ndi 0.2M / sec, chubu chotetezera ndi 5mm.

Kudziwotcha: Kuchuluka kwapano komwe kumaloledwa kudzera pa pt100 ndi ≤5mA, kuchuluka komwe kumaloledwa kudzera pa pt1000 ndi ≤0.5mA

Waya wolumikizira: Waya wa PVC, waya wa silikoni, waya wa PTFE Teflon, waya wazitsulo zamagalasi, ndi zina. Zofunikira pakuyezera kutentha kwapamalo: kukana madzi / kuwononga / kuvala kukana / seismic / zina.

Zindikirani: Zofunikira zapadera, chonde tidziwitse mwatsatanetsatane, zitha kusinthidwa malinga ndi zofunikira.

Weilian Electronic Technology, kutentha, kuthamanga kachipangizo R & D ndi wopanga, chomera chake choposa 3000 lalikulu, zida zamitundu yonse, makina ozindikira bwino, chitsimikizo chamtundu, mtengo wololera! Takulandilani kukambilana ndi mgwirizano.
