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

Dulmar Guud oo ku saabsan Qaybta 1aad

Heerkulka heerkulka ee heerka koowaad iyo labaad ee platinum-iridium 10-platinum kuwaas oo leh saxnaan sare sifooyin jireed iyo kiimiko oo wanaagsan, iska caabin oksaydh wanaagsan heerkulka sare, xasillooni wanaagsan iyo dib-u-soo-saarid awoodda thermoelectromotive. Sidaa darteed, waxaa loo isticmaalaa qalab cabbiraad caadi ah (419.527~1084.62) °C, waxaa sidoo kale loo isticmaalaa in lagu gudbiyo cabbirka heerkulka iyo cabbirka heerkulka saxda ah ee heerka heerkulka.

Qaybta 2 Xuduudaha Farsamada

Tusmada halbeegga	Heerkulka 10-platinum ee fasalka koowaad ee platinum-iridium	Heerkulka 10-platinum ee fasalka labaad ee platinum-iridium
Togan iyo tabanba	Midka togan waa daawaha platinum-rhodium (platinum 90% rhodium 10%), taban waa platinum saafi ah
elektroodh	Dhexroorka laba elektroodh waa 0.5^-0.015Dhererka mm kama yara 1000mm
Shuruudaha xoogga korontada kulka. Heerkulka isgoyska cabbirku waa barta Cu (1084.62℃) Al point (660.323℃) Zn point (419.527℃) heerkulka isgoyska tixraacana 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
Xasilloonida xoogga kuleylka-electromotive	3μV	5μV
Isbeddelka sanadlaha ah Xoogga kuleylka-electromotive ee barta Cu (1084.62℃)	≦5μV	≦10μV

Gacan-gashi dahaadh ah	Tuubo laba god leh oo ah tuubo balaastiig ah ama tuubo corundum ah Dhexroorka dibadda (3~4)mm, dhexroorka godka (0.8~1.0)mm, dherer (500~550)mm

Qaybta 3aad Tilmaamaha Codsiga

Heerkulka caadiga ah ee platinum-iridium 10-platinum waa inuu waafaqsan yahay jadwalka nidaamka keenista qaranka, Habraacyada xaqiijinta qaranka waa in la hirgeliyaa. Heerkulka caadiga ah ee platinum-iridium 10-platinum waxaa loo isticmaali karaa in lagu cabbiro heerka labaad, heerka Ⅰ, heerka Ⅱ ee platinum-iridium 10-platinum thermocouples iyo heerka Ⅰ ee heerka thermalcouples; Heerkulka heerka labaad ee platinum-iridium 10-platinum thermocouples waxaa loo isticmaali karaa oo keliya in lagu cabbiro heerka Ⅱ ee heerka termalcouples birta salka ah

Qaybta 4aad Dayactirka iyo ilaalinta

1. Muddada cabbiraadda heerkulka caadiga ah waa 1 sano, sannad kastana waa in qaybta mitirka lagu hagaajiyaa heerkulka caadiga ah.

2. Habaynta kormeerka ee lagama maarmaanka ah waa in la sameeyaa iyadoo loo eegayo isticmaalka.

3. Deegaanka shaqada ee thermocouple-ka caadiga ah waa inuu ahaadaa mid nadiif ah si looga fogaado wasakheynta thermocouple-ka caadiga ah.

4. Heerkulka caadiga ah waa in la dhigaa xaalad aan wasakhayn oo laga ilaaliyo cadaadiska farsamada.

Qaybta 5aad Taxaddarrada marka la isticmaalayo

1. Tuubada dahaarka laguma isticmaali karo dubista heerkulka sare. Tuubada dahaarka asalka ah waxaa la isticmaalaa ka dib marka si adag loo nadiifiyo oo la dubo heerkul sare.

2. Tuubada dahaarka ayaa iska indha tirta togan iyo taban, taasoo sababi doonta in tiirka platinum-ku wasakhoobo oo qiimaha awoodda kuleyliyaha uu hoos u dhaco.

3. Si aan kala sooc lahayn, tuubada dahaarka ee caadiga ah ee thermocouple-ka oo leh silig raqiis ah ayaa wasakhayn doonta thermocouple-ka caadiga ah, tuubada birta ilaalinta ahna waa in loo isticmaalaa xaqiijinta thermocouple-ka birta salka ah.

4. Heerkulbeegga caadiga ah si lama filaan ah looma dhigi karo foornada heerkulka nidaamisa, mana laga saari karo foornada heerkulka nidaamisa. Kulaylka degdegga ah iyo qabowgu waxay saameyn doonaan waxqabadka heerkulka.

5. Xaaladaha caadiga ah, foornada xaqiijinta ee thermocouple-ka birta qaaliga ah iyo thermocouple-ka birta salka ah waa in si adag loo kala saaraa; haddii aysan suurtagal ahayn, tuubada dhoobada nadiifka ah ama tuubada corundum (dhexroor qiyaastii 15mm ah) waa in lagu dhejiyaa tuubada foornada si looga ilaaliyo birta qaaliga ah thermocouples-ka iyo thermocouples-ka caadiga ah wasakhda thermocouple-ka birta salka ah.
