PR1231/PR1232Platinum-10% Rhodium / Platium Thermocouple

Part1 mwachidule

Woyamba ndi wachiwiri kalasi muyezo platinamu-iridium 10-platinamu thermocouples amene ali mkulu molondola zabwino thupi ndi mankhwala katundu, wabwino makutidwe ndi okosijeni kukana pa kutentha, bata wabwino ndi reproducibility wa mphamvu thermoelectromotive.Chifukwa chake, imagwiritsidwa ntchito ngati chida choyezera mu (419.527 ~ 1084.62) °C, imagwiritsidwanso ntchito kufalitsa kukula kwa kutentha ndi kuyeza kutentha kolondola mumtundu wa kutentha.

Gawo 2 Magawo aukadaulo

Gawo 3Malangizo Ogwiritsira Ntchito

muyezo platinamu-iridium 10-platinamu thermocouples ayenera kukhala molingana ndi dziko yobereka dongosolo tebulo, njira zotsimikizira dziko ayenera kukhazikitsidwa.Choyamba kalasi muyezo platinamu-iridium 10-platinamu thermocouples angagwiritsidwe ntchito kuyeza kalasi yachiwiri, Ⅰ kalasi,Ⅱ kalasi platinamu-iridium 10-platinum thermocouples ndi Ⅰ kalasi m'munsi zitsulo thermocouples;Thermocouples yachiwiri ya platinamu-iridium 10-platinamu imatha kugwiritsidwa ntchito kuyeza Ⅱ giredi m'munsi zitsulo thermocouples

Gawo 4 Kusamalira ndi kusunga

1. Nthawi yofananira ya thermocouple calibration ndi chaka chimodzi, ndipo chaka chilichonse thermocouple yokhazikika iyenera kuyesedwa ndi dipatimenti ya metrology.

2. Kuwongolera koyenera koyang'anira kuyenera kuchitidwa molingana ndi kagwiritsidwe ntchito.

3. Malo ogwirira ntchito a standard thermocouple ayenera kukhala oyera kuti asaipitsidwe ndi thermocouple yokhazikika.

4. Thermocouple yokhazikika iyenera kuikidwa mu chikhalidwe chosaipitsa ndikutetezedwa ku zovuta zamakina.

Gawo 5 Kusamala mukamagwiritsa ntchito

1. Chubu chotchingira sichingagwiritsidwe ntchito pakuwotcha kutentha kwambiri.Chubu choyambirira chotchinjiriza chimagwiritsidwa ntchito pambuyo poyeretsa kwambiri komanso kuwotcha kwambiri.

2. The insulation chubu imanyalanyaza zabwino ndi zoipa, zomwe zidzachititsa kuti mtengo wa platinamu ukhale woipitsidwa ndi mphamvu ya thermoelectric mphamvu kuti ikhale yochepa.

3. Mwachisawawa chubu chokhazikika cha thermocouple chokhala ndi waya wotchipa chimayipitsa thermocouple, ndipo chubu chachitsulo choteteza chiyenera kugwiritsidwa ntchito potsimikizira maziko azitsulo thermocouple.

4. Thermocouple yokhazikika sichikhoza kuikidwa mwadzidzidzi mu ng'anjo yoyendetsa kutentha, kapena kuchotsedwa mu ng'anjo yoyendetsa kutentha.Kutentha kwadzidzidzi ndi kuzizira kudzakhudza ntchito ya thermoelectric

5.Panthawi yanthawi zonse, ng'anjo yotsimikizira ya thermocouple yamtengo wapatali yachitsulo ndi thermocouple yoyambira yachitsulo iyenera kukhala yosiyana kwambiri;ngati kuli kotheka, chubu choyera cha ceramic kapena chubu cha corundum (m'mimba mwake pafupifupi 15mm) chiyenera kuikidwa mu chubu cha ng'anjo kuti chitetezere zitsulo zamtengo wapatali za Thermocouples ndi ma thermocouples okhazikika kuti asawonongeke ndi zitsulo za thermocouple.
