PR1231/PR1232 Heerka Platinum-10% Rhodium/Platium Thermocouple

Qaybta1 Dulmar

Heerka koowaad iyo labaad heerka platinum-iridium 10-platinum heerkulbeegyada kuwaas oo leh saxnaan sare oo wanaagsan oo muuqaal iyo kiimiko ah, iska caabin oksaydh oo wanaagsan heerkul sare, xasillooni wanaagsan iyo dib u soo saarida xoogga korantada.Sidaa darteed, waxaa loo isticmaalaa sida qalabka cabbiraadda caadiga ah ee (419.527 ~ 1084.62) ° C, waxaa sidoo kale loo isticmaalaa in lagu gudbiyo cabbirka heerkulka iyo cabbirka heerkulka saxda ah ee kala duwanaanta heerkulka.

Qeybta 2 ee cabbirada farsamada

Tusmada cabbirka	Heerka kowaad ee platinum-iridium 10-platinum heerkulbeegyada	Heerka labaad ee platinum-iridium 10-platinum thermocouples
Togan iyo taban	Midka togan waa daawaha platinum-rhodium (platinum 90% rhodium 10%), xumaantu waa platinum saafi ah.
electrode	Dhexroorka laba electrodes waa 0.5^-0.015Dhererka mm kama yarayn 1000mm
Shuruudaha xoogga kuleyliyaha kuleylka Cabbirka heerkulka isgoysyada waa Cu dhibic (1084.62 ℃) Al dhibic (660.323 ℃) dhibicda Zn (419.527 ℃) iyo heerkulka isgoysyada tixraaca waa 0℃	E (t_Cu)=10.575±0.015mVE(t_Al)=5.860+0.37 [E(t_Cu) -10.575]±0.005mVE(t_Zn= 3.447+0.18 [E (t_Cu) -10.575]±0.005mV
Xasiloonida xoogga Thermo-electromotive	3μV	5μV
Isbedelka sannadlaha ah ee Thermo-electromotive Force at Cu dhibic (1084.62 ℃)	≦5μV	≦10μV
Qiyaasta heerkulka shaqada	300 ~ 1100 ℃
Gacan dahaadh	Tuubbada dhoobada labajibbaaran ama tube corundum Dhexroorka dibadda (3 ~ 4) mm, dhexroor dalool (0.8 ~ 1.0) mm, dhererka (500 ~ 550) mm

Qaybta 3aad Tilmaamaha Codsiga

Heerkulbeegyada caadiga ah ee platinum-iridium 10-platinum waa inay ahaadaan kuwo waafaqsan shaxda nidaamka bixinta qaranka, waa in la hirgeliyaa habraacyada xaqiijinta qaranka.Heerka darajada koowaad platinum-iridium heerkulbeegyada 10-platinum waxaa loo isticmaali karaa in lagu cabbiro fasalka labaad,Ⅰ darajada,Ⅱ heerka platinum-iridium 10-platinum heerkulbeegyada iyo Ⅰ heerkulbeegyada birta ah ee darajada;Heerka labaad ee platinum-iridium 10-platinum thermocouples waxa kaliya oo loo isticmaali karaa in lagu cabbiro Ⅱ heerkulbeegyada birta ee saldhigga ah

Koodhka xaqiijinta qaranka	Magaca xaqiijinta qaranka
JJG75-1995	Platinum-iridium caadiga ah 10-platinum thermocouples qeexitaanka cabbirka
JJG141-2013	Shaqeynta biraha qaaliga ah ee heerkulbeegyada cabbirka qeexida

Qaybta4 Dayactirka iyo ilaalinta

1. Muddada heerkulbeegga caadiga ah waa 1 sano, sannad walbana heerkulbeegga caadiga ah waa in lagu cabbiraa waaxda metrology.

2. Isku-habaynta kormeerka lagama maarmaanka ah waa in lagu sameeyaa si waafaqsan isticmaalka.

3. Deegaanka shaqada heerkulbeegga caadiga ah waa inuu ahaadaa nadiif si looga fogaado wasakheynta heerkulka caadiga ah.

4. Heerkulbeegga caadiga ah waa in lagu dhejiyaa xaalad aan wasakhayn oo laga ilaaliyo cadaadiska farsamada.

Qaybta 5 Taxaddar marka la isticmaalayo

1. Tuubada dahaarka lama isticmaali karo marka la dubayo heerkul sare.Tuubada dahaarka asalka ah ayaa la isticmaalaa ka dib nadiifin adag iyo dubay heerkul sare ka dib.

2. Tuubada dahaarka ayaa iska indha tirta togan iyo kuwa taban, taas oo keeni doonta in tiirka platinum uu wasakheeyo iyo in qiimaha kuleylku hoos u dhaco.

3. Si aan kala sooc lahayn tuubbada dahaarka heerkulbeegga caadiga ah ee leh silig raqiis ah ayaa wasakhayn doonta heerkulbeegga caadiga ah, iyo tuubada birta ah ee difaaca waa in loo adeegsadaa xaqiijinta heerkulbeegga birta ee salka.

4. Heerkulbeegga caadiga ah lama si lama filaan ah loo gelin karo foornada heerkulbeegga, lagamana soo saari karo foornada heer-kulka heer-kulka ah.Kulaylka lama filaanka ah iyo qabowgu waxay saameeyaan waxqabadka heerkulbeegga

5.Under xaaladaha caadiga ah, foornada xaqiijinta ee heerkulbeegga birta ah ee qaaliga ah iyo heerkulbeegga birta ee saldhigga ah waa in si adag loo kala saaraa;Haddii aysan suurtogal ahayn, tuubada dhoobada nadiifka ah ama tube corundum (dhexroor qiyaastii 15mm) waa in la geliyaa tuubada foornada si looga ilaaliyo birta qaaliga ah Thermocouples iyo heerkulbeegyada caadiga ah ee wasakhowga kuleylaha birta ah.
