4-20mA tso zis taw qhia

Ntau lub ntsuas hluav taws xob xaiv siv tam sim no los xa cov teeb liab, vim tias tam sim no tsis muaj suab nrov.Lub voj tam sim no ntawm 4 ~ 20mA yog 4mA los sawv cev rau xoom teeb liab, 20mA los sawv cev rau tag nrho cov nplai ntawm cov teeb liab, thiab cov teeb liab hauv qab 4mA thiab siab dua 20mA yog siv rau lub tswb ntawm ntau yam txhaum.4-20MA tso zis ntawm Lanrui cov khoom siv yog nquag 4-20MA teeb liab tshwj tsis yog dej ntsuas, micro ntws ntsuas thiab ntsuas kub.Cov zis ntawm lub ntsuas dej 4-20mA yog passive.Yog li ntawd, thaum siv 4-20mA tso zis ntawm ob-xaim dej ntsuas, cov cuab yeej tau txais cov cim tam sim no yuav tsum ua haujlwm. Lub Sijhawm Difference series: M53-M58 cov ntawv qhia zaub mov yog siv los ntsuas, teeb tsa thiab txheeb xyuas cov zis 4-20MA.

1. Doppler series meter: OUTPUT1 xaiv 4-20 mA.Flow 4mA teeb tsa cov Flow instantaneous rau 4 mA.Flow 20mA teem caij tam sim no rau 20mA.Dej ntsuas dej / Cov dej me me: Thawj tus lej ntawm CFU ntawv qhia zaub mov yog teem rau 2 kom tig rau cov zis tam sim no.

FF cov ntawv qhia zaub mov teeb 20mA kom sib haum mus rau qhov nrawm nrawm;4mA qhia tias kev khiav ceev ceev yog 0 thiab tsis muaj ntawv qhia zaub mov teeb.

2. Area-velocity series meter: nyob rau hauv cov zis submenu, xaiv 4-20 ma thiab teem lub instantaneous ntws ntawm 4 mA thiab 20mA.

3. Flume thiab weirs hom qhib channel series: nyob rau hauv qhov chaw tsis txaus, xaiv 4-20 mA los teeb tsa qhov tam sim no ntws ntawm 20mA thiab 0 rau 4 mA.Tsis muaj ntawv qhia zaub mov.
