Qhov sib txawv ntawm qib kawm ib thiab qib qib ib ntawm thermocouple e ntaus

Kev ntsuas cov qib yog siv los ntsuas cov ntsuas kub hauv cov txheej txheem ntau lawm, thiab cov nqi qib kub ntawm cov txheej txheem kub ntau dua 50 npaug ntawm cov qib kev lag luam thermocouple!

Ib .2.2 Tsis muaj kev sim ua ntej kev sim thermocouple yog qhov ntsuas kub ntawm lub ntsej muag, thiab qhov kev ncua deb ntawm ob yog hais txog 250 hli . Tom qab ntawd cia qhov ntsuas thermocouple muaj kev puas tsuaj rau cov pa hluav taws xob, thiab ntsuas cov khoom siv hluav taws xob tsis kam ntawm cov tshooj raws li Tshooj3.3.
A.2.3 Vibration Test according to GB4451-84 "Vibration (Sinusoidal) Test Method for Industrial Automation Instruments". The vibration level can be selected as 2B or 2C according to actual conditions. After the test, immediately check whether the tested thermocouple has mechanical damage. Whether there is open circuit or short circuit, and measure lub rwb thaiv tsev tsis kam nqi ntawm chav sov raws li tshooj 3.3.
