Chikamu3Mirayiridzo 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.
