Dab tsi yog qhov txawv ntawm Hom E thiab Hom J thermocouples

Qhov sib txawv tseem ceeb ntawm Hom E thiab Hom J thermocouples nyob rau hauv lawv cov khoom muaj pes tsawg leeg, qhov kub thiab txias, cov yam ntxwv rhiab heev, kev hloov pauv ib puag ncig, thiab cov ntawv thov raug xwm txheej. Ob leeg yog lub hauv paus hlau thermocouples, tab sis lawv muaj kev ua haujlwm sib txawv: Hom E paub txog nws qhov kev xav tau siab, tsim nyog rau kev kuaj xyuas qhov sib txawv me me; Hom J muaj kev tiv thaiv zoo rau kev txo qis, haum rau kev lag luam ib puag ncig uas muaj hydrogen lossis carbon monoxide.

 

I. Cov Khoom Siv: Nickel-Chromium-Copper-Nickel vs. Iron-Constantan

Hom E Thermocouple (Nickel-Chromium-Copper-Nickel/Constantan): Qhov zoo electrode yog nickel-chromium alloy (EP), thiab cov electrode tsis zoo yog tooj liab-nickel alloy (EN), tseem hu ua "constantan." Cov khoom siv sib xyaw ua ke ua rau nws muaj peev xwm ua tau zoo tshaj plaws thermoelectric ntawm tag nrho cov txheej txheem thermocouples.

Hom J Thermocouple (Hlau-Constantan): Qhov zoo electrode yog hlau ntshiab (JP), thiab cov electrode tsis zoo yog tooj liab-nickel alloy (JN). Cov khoom siv electrode tsis zoo yog tib yam li Hom E, tab sis cov khoom siv electrode zoo sib txawv. Siv hlau ua cov electrode zoo ua rau nws ua tau zoo dua hauv kev txo cov cua.

Xaus: Hom E yog tsim rau cov ntawv thov uas xav tau cov teeb liab tso zis siab; Hom J yog tsim nyog rau kev lag luam ib puag ncig nrog txo cov pa roj.

 

II. Kev sib piv ntawm qhov kub thiab txias: Hom E muaj ntau qhov ntsuas kub qis thiab nruab nrab, thaum Hom J feem ntau yog siv rau qhov nruab nrab kub.

Rooj: Hom	Ntev -Lub Sijhawm Ua Haujlwm Kub	Luv -Lub Sij Hawm Nrog Kub	Kev ntsuas qhov ua tau zoo
Hom E	900 degree	1000 degree	-270 ~ 900 degree
Hom J	500 ~ 750 degree	750 degree	-210 ~ 1200℃(Feem ntau siv 0 ~ 750 degree)

Hom E thermocouples npog ntau yam ntawm cryogenic mus rau nruab nrab qhov kub thiab txias, ua haujlwm ruaj khov los ntawm -270℃txog 900 degree, ua rau lawv tshwj xeeb tshaj yog haum rau kev lag luam rhiab rau qhov kub hloov pauv, xws li khoom noj thiab tshuaj.

Hom J muaj qhov siab dua qhov ntsuas qhov ntsuas qhov ntsuas kub, tab sis hauv kev xyaum, nws feem ntau txwv qis dua 750℃vim tias cov hlau cathode yog qhov ua rau oxidation thiab embrittlement ntawm qhov kub thiab txias, ua rau tawg lossis drift.

Lus Cim: Hom E thermocouples tsis tuaj yeem siv rau hauv sulfur-muaj lossis txo cov cua; Hom J thermocouples yuav tsum tsis txhob siv nyob rau hauv siab -kub oxidizing ib puag ncig yam tsis muaj kev tiv thaiv.

III. rhiab heev thiab teeb liab tso zis yam ntxwv

Hom E Thermocouple: Nrog rau qhov ntsuas kub ntawm kwv yees li 68 μV / degree, nws boasts qhov siab tshaj plaws ntawm txhua tus qauv thermocouples. Qhov no txhais tau hais tias nws tuaj yeem kuaj xyuas qhov ntsuas kub me me, ua rau nws zoo tagnrho rau cov ntawv thov thermopile, infrared detectors, lossis multi-point ntsuas kub ntsuas tshuab.

Hom J Thermocouple: Nrog rau qhov ntsuas kub ntawm kwv yees li 50 ~ 51 μV / degree, nws qhov rhiab heev yog siab dua Hom K tab sis qis dua Hom E. Nws qhov zoo nyob hauv nws cov teeb liab loj dua thiab zoo dua linearity, nrog qhov yuam kev me me hauv 0 ~ 750℃ntau.

Piv txwv piv txwv: Ntawm 100 degree, Hom E tso tawm kwv yees li 6.3mV, thaum Hom J tso tawm kwv yees li 5.2mV. Hom E teeb liab lub zog yog kwv yees li 20% siab dua, ua rau nws tsim nyog rau qis - zog lossis tsis yog - amplifier systems.

IV. Environmental Adaptability thiab kev txwv kev siv

Rooj Environmental Type	E- hom Kev Ua Haujlwm	J-type Performance
Oxidizing Atmosphere	Siv tau, oxidation zoo dua li J / T hom	Hlau cathode yog yooj yim oxidized saum 500 degree, tiv thaiv tube yuav tsum tau
Txo Huab Cua	Tsis tuaj yeem siv ncaj qha, yooj yim deteriorates	Siv tau, tiv taus H₂ thiab CO gas corrosion
Inert/Vacuum Ib puag ncig	Siv tau	Siv tau, haum rau ntau yam kev ua haujlwm
Humidity Ib puag ncig	Tsis rhiab rau high humidity	Resistant mus rau noo noo, haum rau humid ua hauj lwm tej yam kev mob
Ntev - Lub Sij Hawm Stability	Nruab nrab, tsis zoo thermoelectric tej zaum uniformity	Nruab nrab, yooj yim oxidized thiab deteriorates ntawm qhov kub thiab txias

Kev pom zoo: Hom E yog siv rau kev ua kom tsis muaj zaub mov, kev saib xyuas ib puag ncig, thiab lwm yam xwm txheej uas yuav tsum tau teb siab; Hom J yog tsim rau cov chaw lag luam nrog txo cov roj, xws li roj refining thiab tshuaj industries.

V. Kev sib piv ntawm Daim Ntawv Thov Kev Sib Tham

Hom E thermocouples yog dav siv nyob rau hauv kev ua zaub mov, tshuaj sterilization, lom incubators, ib puag ncig kub tswj systems, thiab lwm yam teb uas yuav tsum tau ceev teb thiab rhiab heev. Vim nws cov teeb liab tso zis muaj zog, nws kuj tau siv dav hauv kev qhia kev sim thiab cov cuab yeej nqa tau yooj yim.

hom thermocouples feem ntau yog siv rau hauv cov chaw lag luam xws li yas txhaj tshuaj molding tshuab, boilers me me, roj refineries, thiab tshuaj reactors, qhov twg txo qhov cua nyob los yog nqi yog ib qho kev txhawj xeeb. Vim tias lawv cov nqi qis thiab cov teeb liab muaj zog, lawv kuj tau siv los ua ib ntus hloov kho cov cuab yeej siv.
