● Kev qhia khoom
LF-0020 dej kub sensor (transmitter) siv high-precision thermistor ua cov khoom siv ntsuas, uas muaj cov yam ntxwv ntawm qhov ntsuas qhov tseeb thiab ruaj khov zoo. Lub teeb liab transmitter tau txais kev sib koom ua ke ntawm cov khoom siv hluav taws xob siab tshaj plaws, uas tuaj yeem hloov qhov kub thiab txias rau hauv qhov sib txuam voltage lossis tam sim no teeb liab raws li kev xav tau sib txawv ntawm cov neeg siv. Cov cuab yeej yog me me, yooj yim rau nruab thiab nqa tau yooj yim, thiab muaj kev ua tau zoo; nws txais yuav cov kab muaj tswv, zoo linearity, muaj peev xwm thauj khoom, kev sib kis ntev, thiab muaj peev xwm tiv thaiv kev cuam tshuam. Nws tuaj yeem siv dav rau kev ntsuas kub hauv thaj tsam ntawm huab cua, ib puag ncig, kuaj, kev lag luam thiab kev ua liaj ua teb.

●Kev suav cov qauv
Hom hluav taws xob (0 ~ 5V):
T = V / 5 × 70 -20
(T yog qhov ntsuas kub tus nqi (℃), V yog qhov tso zis hluav taws xob (V), cov qauv no sib raug rau qhov ntsuas ntau -20 ~ 50 ℃)
T = V / 5 × 150 -50
(T yog qhov ntsuas kub tus nqi (℃), V yog qhov tso zis hluav taws xob (V), cov qauv no sib haum rau qhov ntsuas ntau -50 ~ 100 ℃)
Hom tam sim no (4 ~ 20mA)
Luas = (I-4) / 16 × 70 -20
(T yog qhov ntsuas kub tus nqi (℃), Kuv yog qhov tso zis tam sim no (mA), hom no sib haum mus rau qhov ntsuas ntau -20 ~ 50 ℃)
T = (I-4) / 16 × 150 -50
(T yog qhov ntsuas kub tus nqi (℃), Kuv yog cov zis tam sim no (mA), cov qauv no sib haum rau qhov ntsuas qhov ntsuas -50 ~ 100 ℃)
Nco tseg: Cov qauv kev suav suav suav nrog cov teeb liab sib txawv thiab cov kev ntsuas sib txawv yuav tsum tau rov suav dua!
