K-Type Thermocouple Waya 2 * 0.8mm (800 ℃ Fiberglass) ya Kutentha Kwambiri
Mafotokozedwe Akatundu
Type K Thermocouple Cable (2 * 0.8mm) yokhala ndi 800 ℃ Fiberglass Insulation & Sheath
Zowonetsa Zamalonda
Chingwe cha Type K thermocouple (2 * 0.8mm) chochokera ku Tankii Alloy Material ndi njira yapadera yodziwira kutentha yomwe imapangidwira m'malo opangira mafakitale. Ili ndi ma conductor awiri a mainchesi a 0.8mm (Chromel ya zabwino, Alumel ya negative) - siginecha ya aloyi awiri amtundu wa K thermocouples - okhala ndi chitetezo chamitundu iwiri: ma conductor omwe amatsekeredwa ndi magalasi a fiberglass ovotera 800 ℃, kuphatikiza sheath yonse ya 800 ℃ fiberglass. Kapangidwe ka magalasi a fiberglass awiriwa, kuphatikiza ndi kupanga kolondola kwa Huona, kumapereka kukana kutentha kosayerekezeka, kukhazikika kwazizindikiro, ndi kulimba, ndikupangitsa kuti ikhale chisankho chapamwamba pamiyezo yopitilira kutentha kwambiri komwe kutsekereza kokhazikika (silicone, PVC) kumalephera.
Maudindo Okhazikika
- Mtundu wa Thermocouple: K (Chromel-Alumel)
- Kufotokozera kwa Conductor: 2 * 0.8mm (awiri 0.8mm m'mimba mwake thermocouple alloy conductors)
- Insulation / Sheath Standard: Fiberglass imagwirizana ndi IEC 60751 ndi ASTM D2307; idavotera 800 ℃ kugwiritsidwa ntchito mosalekeza
- Wopanga: Tankii Alloy Material, yovomerezeka ku ISO 9001 ndi IECEx pazogwiritsa ntchito zoopsa / kutentha kwambiri
Ubwino Waikulu (kuyerekeza ndi Zingwe Zokhazikika za Mtundu wa K)
Chingwechi chimaposa zingwe wamba za Type K zokhala ndi zotchingira kutentha pang'ono m'malo atatu ovuta:
- Kulimbana ndi Kutentha Kwambiri: 800 ℃ kutentha kosalekeza (kwakanthawi kochepa mpaka 900 ℃ kwa ola limodzi)—zingwe zotsekereza silikoni (≤200 ℃) ndi magalasi wamba a fiberglass (≤450 ℃)—othandizira kuti agwiritsidwe ntchito pafupi ndi moto.
- Kukhalitsa Kwamagawo Awiri: Kupaka kwa fiberglass payekha (kwa kondakitala kudzipatula) + sheath yonse ya fiberglass (yoteteza makina) imachulukitsa kukana kwa abrasion, dzimbiri la mankhwala, ndi ukalamba wamatenthedwe; moyo wautumiki 3x wautali kuposa zingwe zotsekereza imodzi.
- Kulondola kwa Chizindikiro Kosasunthika: 0.8mm Makondakitala a Chromel-Alumel amachepetsa kutsika kwa ma siginecha, kusunga mtundu wa K wa muyezo wa thermoelectric output (41.277mV pa 1000 ℃ vs. 0 ℃ reference) ngakhale pa 800 ℃, ndikuyendetsa <0.1% pambuyo pa maola 50 pa 50 pa 0.0
- Chitetezo Cholimbidwa: Chosawotcha moto (mlingo wa UL 94 V-0), chosakhala ndi poizoni, komanso utsi wochepa—chotetezeka kuti chigwiritsidwe ntchito m’malo otsekeredwa m’mafakitale (monga ng’anjo, ma boilers) kumene kuopsa kwa moto kuli kwakukulu.
