Cov hau kev los txhim kho qhov ntsuas qhov tseeb ntawm thermoco

1. Muaj thawj-xaj thiab kev txiav txim siab thib ob rau s-scatch calibration, uas yog qhov tseem ceeb rau cov nplai ntsuas kub qhia thiab ntsuas seev. Lawv yog kim. Tus nqi rau ib lub meter 'ntev yog nruab nrab ntawm 8000-20000! Muaj cov khoom lag luam muaj xws li I6 5}} [{}}}

2. B tshooj theem II + / -0. 25% t, qib III + / {}. 5% t

3. Theem Kuv muaj tus nqi zoo lossis tsis zoo ntawm 0. 4% t, thaum theem II muaj tus nqi zoo lossis tsis zoo}. 75% t

Qhov twg yog qhov twg peb yuav tsum tsis txhim kho cov qib raug uas tau hais tseg saum toj no? Muaj pes tsawg ntawm cov ntsiab lus hauv qab no yuav tsum tau npaj tseg:

1. Xaiv raws li cov vev xaib xav tau thaum lub sijhawm npaj.

2. Siv high-precision thermocouples.

3. Thaum xaiv ib qho thermocouple, xaiv cov nplai tsim nyog, xaiv qhov tsim nyog thermocouple rau qhov kub thiab txias, thiab txiav txim siab ncaj ncees rau cov nplai sib xws.

4. Siv cov khoom siv siab ntsuas kev ua tau zoo.

5. Nqa cov txheej txheem ntawm cov txheej txheem ntawm qhov chaw kom muaj kev ntxhov siab.
