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

Pfupiso yeChikamu 1

Ma thermocouples emhando yekutanga neyechipiri eplatinum-iridium 10-platinum ane kunyatsorongeka, ane hunhu hwakanaka hwemuviri uye hwemakemikari, anodzivirira oxidation zvakanaka pakupisa kwakanyanya, akasimba uye anogona kudzokororwazve kwesimba re thermoelectromotive. Saka, inoshandiswa sechishandiso chekuyera chakajairwa mu (419.527~1084.62) °C, inoshandiswawo kuyera kupisa kwehukuru uye kupisa kwakanyatsojeka munzvimbo yekupisa.

Chikamu 2 Magadzirirwo ehunyanzvi

Rudzi rweparameter	Mathermocouple eplatinum-iridium 10-platinum egiredhi rekutanga	Platinum-iridium 10-platinum thermocouples dzegiredhi rechipiri
Zvakanaka nezvakaipa	Chinhu chakanaka iplatinum-rhodium alloy (platinum 90% rhodium 10%), asi chisina kunaka iplatinum chaiyo.

Chikamu 3 Mirayiridzo Yekushandisa

Mathermocouple eplatinum-iridium 10-platinum akajairika anofanira kuenderana netafura yenyika yekutumira, maitiro ekuongorora nyika anofanira kushandiswa. Mathermocouple eplatinum-iridium 10-platinum akajairika egiredhi rekutanga anogona kushandiswa kuyera mathermocouple egiredhi rechipiri, giredhi reⅠ, giredhi reⅡ platinum-iridium 10-platinum uye mathermocouple esimbi egiredhi reⅠ; Mathermocouple eplatinum-iridium 10-platinum akajairika egiredhi rechipiri anogona kushandiswa kuyera mathermocouple esimbi egiredhi reⅡ

Kodhi yenyika yekusimbisa	Zita rekusimbisa nyika
JJG75-1995	tsananguro yekuenzanisa thermocouples yeplatinum-iridium 10-platinum yakajairwa
JJG141-2013	Kushanda kwesimbi inokosha thermocouples calibration specification
JJF1637-2017	tsananguro yekuongorora thermocouple yesimbi yesimbi

Chikamu 4 Kugadzirisa nekuchengetedza

1. Nguva yakatarwa yekuyera thermocouple igore rimwe chete, uye gore rega rega thermocouple yakatarwa inofanira kuyera nedhipatimendi remetrology.

2. Kuongororwa kwekutarisira kunodiwa kunofanira kuitwa zvichienderana nekushandiswa.

3. Nzvimbo yebasa ye thermocouple yakajairika inofanira kunge yakachena kudzivirira kusvibiswa kwe thermocouple yakajairika.

4. Thermocouple yakajairika inofanira kuiswa munzvimbo isina kusvibisa uye yakachengetedzwa kubva mukumanikidzwa kwemagetsi.

Chikamu 5 Chenjedzo pakushandisa

1. Chubhu yekudzivirira haigone kushandiswa pakugocha panopisa zvakanyanya. Chubhu yekudzivirira yekutanga inoshandiswa mushure mekucheneswa zvakanyanya uye kugocha pakupisa kwakanyanya.

2. Chubhu yekudzivirira haiteereri zvakanaka nezvakaipa, izvo zvichaita kuti danda replatinum rive rakasvibiswa uye kukosha kwe thermoelectric kudzikire.

3. Chirimwa chepurasitiki che thermocouple chine waya yakachipa chinosvibisa thermocouple yakajairwa, uye chubhu yesimbi inodzivirira inofanira kushandiswa kusimbisa thermocouple yesimbi yakadzika.

4. Thermocouple yakajairika haigone kuiswa kamwe kamwe muchoto chinodzora tembiricha, kana kubviswa muchoto chinodzora tembiricha. Kupisa nekutonhora kunokanganisa mashandiro ethermoelectric

5. Mumamiriro ezvinhu akajairwa, choto chekusimbisa che thermocouple yesimbi inokosha uye thermocouple yesimbi yepasi inofanira kunyatsosiyaniswa; kana zvisingaite, chubhu yakachena yeceramic kana chubhu ye corundum (dhayamita inosvika 15mm) inofanira kuiswa muchubhu yefurnace kudzivirira Thermocouples yesimbi inokosha uye thermocouples dzakajairwa kubva mukusvibiswa kwe thermocouple yesimbi yepasi.
