Txheej txheem cej luam

Lub thermocouple input isolation kev nyab xeeb thaiv tuaj yeem xa cov teeb liab millivolt los ntawm thermocouple (TC) hauv thaj chaw txaus ntshai mus rau thaj chaw nyab xeeb hauv 1: 1.

Cov khoom no xav tau lub hwj chim ywj pheej, nrog rau lub hwj chim cais, cov khoom nkag, thiab cov qhov tso zis.

"*" sawv cev rau hom kev nkag ntawm lub thermocouple, thiab tus qauv tshwj xeeb yog sawv cev los ntawm tus lej (saib "Input Signal Type and Range Table" kom paub meej ntxiv).

Cov hom teeb liab nkag thiab qhov ntsuas ntau yam

1	K	-200~1370℃	50 ℃	0.5 ℃ / 0.1%
2	S	-50~1760℃	500 ℃	1.5 ℃ / 0.1%
3	THIAB	-140~1000℃	50 ℃	0.5 ℃ / 0.1%
4	J	-160~1200℃	50 ℃	0.5 ℃ / 0.1%
5	B	250 ~ 1800 ℃	500 ℃	1.5 ℃ / 0.1%
6	T	-200~400℃	50 ℃	0.5 ℃ / 0.1%
7	R	-50~1760℃	500 ℃	1.5 ℃ / 0.1%
8	N	-200~1300℃	50 ℃	0.5 ℃ / 0.1%
