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

Part1 Overview

Yekutanga neyechipiri giredhi mwero platinum-iridium 10-platinum thermocouples ine yakakwirira kunyatso hunhu hwakanaka hwemuviri uye makemikari zvivakwa, yakanaka oxidation kuramba pakupisa kwakanyanya, kugadzikana kwakanaka uye kuberekazve kwesimba rethermoelectromotive.Naizvozvo, inoshandiswa seyakajairwa yekuyeresa chiridzwa mu (419.527 ~ 1084.62) °C , inoshandiswawo kuendesa tembiricha kuendesa uye chaiyo tembiricha kuyerwa mutembiricha renji.

Part2 Technical parameters

Parameter index	Giredhi rekutanga platinamu-iridium 10-platinum thermocouples	Chechipiri giredhi platinum-iridium 10-platinum thermocouples
Zvakanaka uye zvakaipa	Iyo yakanaka iplatinum-rhodium alloy (platinum 90% rhodium 10%), iyo isina kunaka iplatinum yakachena.
electrode	Ma electrode maviri dhayamita 0.5^-0.015mm kureba hakusi pasi pe1000mm
Zvinodiwa zve thermal electromotive forceMeasure junction tembiricha iri paCu point(1084.62 ℃）Al point(660.323℃)Zn point(419.527℃) uye referensi junction tembiricha i0℃	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

Chikamu3 Mirayiridzo Yekushandisa

yakajairwa platinamu-iridium 10-platinum thermocouples inofanirwa kunge inoenderana neiyo nyika dhizaini system tafura, National verification maitiro anofanirwa kuitwa.Chekutanga giredhi standard platinum-iridium 10-platinum thermocouples inogona kushandiswa kuyera yechipiri giredhi, Ⅰ giredhi, Ⅱ giredhi platinum-iridium 10-platinum thermocouples uye Ⅰ giredhi base metal thermocouples;Chechipiri giredhi platinum-iridium 10-platinum thermocouples inogona chete kushandiswa kuyera Ⅱ giredhi base base simbi thermocouples.

National verification code	Zita rekuongorora renyika
JJG75-1995	standard platinum-iridium 10-platinum thermocouples calibration tsanangudzo
JJG141-2013	Kushanda yakakosha simbi thermocouples calibration yakatarwa
JJF1637-2017	base metal thermocouple calibration yakatarwa

Chikamu 4 Kuchengetedza uye kuchengetedza

1. Iyo yakajairwa thermocouple calibration nguva i1 gore, uye gore rega rega iyo yakajairwa thermocouple inofanirwa kuenzaniswa nedhipatimendi remetrology.

2. Iyo inodiwa yekutarisa calibration inofanira kuitwa maererano nekushandiswa.

3. Mamiriro ekushanda emhando ye thermocouple inofanira kuva yakachena kuti irege kusvibiswa kweiyo standard thermocouple.

4. Thermocouple yakajairika inofanira kuiswa mumamiriro asina kusvibiswa uye inodzivirirwa kubva kune mechanical stress.

Chikamu 5 Chengetedzo kana uchishandiswa

1. The insulation tube haigoni kushandiswa pakupisa kwepamusoro kugocha.Iyo yekutanga insulation chubhu inoshandiswa mushure mekuchenesa kwakasimba uye yakanyanya kupisa kupisa.

2. The insulation tube inofuratira zvakanaka uye zvakaipa, izvo zvichaita kuti danda replatinum rive rakasvibiswa uye thermoelectric inogona kukosha kuderera.

3. Nenguva isipi iyo standard thermocouple insulation chubhu ine waya yakachipa inosvibisa iyo standard thermocouple, uye inodzivirira simbi chubhu inofanira kushandiswa kuongororwa kwe base metal thermocouple.

4. Iyo yakajairika thermocouple haigone kuiswa kamwe kamwe muchoto chekushisa-chinodzora, kana kutorwa kubva muchoto chekushisa-chinodzora.Iko kamwe-kamwe-kupisa uye kutonhora kuchakanganisa iyo thermoelectric performance

5.Mumamiriro ezvinhu akajairika, choto chekusimbisa chesimbi yakakosha thermocouple uye base metal thermocouple inofanira kunyatsosiyaniswa;kana zvisingaite, iyo yakachena ceramic chubhu kana corundum chubhu (dhayamita ingangoita 15mm) inofanira kuiswa muchoto chubhu kudzivirira yakakosha simbi Thermocouples uye yakajairwa thermocouples kubva pabase metal thermocouple kusvibiswa.
