Taw qhia rau tus ua hauj lwm cov ntsiab cai ntawm platinum-rhodium thermocouple!

Platinum-rhodium thermocouple yog ib qho khoom siv hlau thermocouple. Lub taub hlau xaim yog teev raws li 0. 5mm, nrog kev sib txawv ntawm {}}. 015mm. Lub nominal tshuaj muaj pes tsawg leeg ntawm qhov zoo electrode (bp) yog platinum-rhodium alloy, uas muaj 30% rho tawm thiab 70% Platinum. Qhov tsis zoo electrode (bn) yog ib qho platinum-rhodium alloy, uas muaj 6% thim rov qab, yog li nws feem ntau yog hu ua ob lub platinum-rhodium thermocouple. Qhov siab tshaj plaws ntev siv qhov kub ntawm no thermocouple yog 1600 degree, thiab qhov siab tshaj plaws luv luv siv kub yog 1800 degree.

Cov txiaj ntsig: Plymum-Rhodium Thermocouple muaj qhov tseeb tshaj plaws, kev ntsuas kub zoo tshaj plaws, thiab siab tshaj qhov ntsuas kub ntev, thiab cov ntsuas kub siab ntev tshaj plaws hauv kev ntsuas thermocouple. Nws yog qhov haum rau oxidizing thiab inert atmospheres, thiab tseem siv tau rau lub tshuab nqus tsev rau lub sijhawm luv luv, tab sis tsis yog rau kev txo cov cua nab kuab lossis cov cua sov uas muaj cov hlau tsis muaj hlau. Ib qho txiaj ntsig pom tseeb ntawm hom b thermouples yog tias lawv tsis tas yuav tsum tau nyiaj, vim hais tias lub peev xwm thov nyiaj rau kev them nyiaj, vim hais tias lub thermoelectric muaj peev xwm tsawg dua 3μv nyob rau hauv thaj tsam ntawm {}} ~ 50 degree.

Disadvantages: The disadvantage of platinum-rhodium thermocouples is the thermoelectric potential, the thermoelectric potential rate is small, the sensitivity reading is low, the mechanical strength decreases at high temperature, it is very sensitive to pollution, and the precious metal materials are expensive, so the one-time investment is large.

Tus txheej txheem ua hauj lwm ntawm platinum-rhodium thermocoidles yog tias thaum ob qho kub ntawm ob lub junctionsts yog txawv, ib lub thermal tam sim no yuav tsim tawm hauv lub voj. Yog tias muaj qhov sib txawv kub ntawm qhov ua haujlwm kawg thiab qhov kawg ntawm thermocouple, cov zaub cov peev txheej yuav qhia tau tias muaj txiaj ntsig kub kom sib haum los ntawm thermocouple.

Xaiv Platinum-Rhodium Thermocouples: Thaum ib txwm muaj kev ntsuas kub (platinum-Rhodium-Rhodium-Rhodium-Rhodium 30- platinum-rhodium-saudium 6), yog li cov kev pab cuam lub neej ntawm lub platinum-Rhodium thermocouple tuaj yeem tuaj yeem lav hauv qhov kub siv.
