I-4-20mA imveliso yentshayelelo

Iimitha ezininzi zemizi-mveliso zikhetha ukusebenzisa i-current ukuhambisa imiqondiso, kuba okwangoku akukhathali kwingxolo.I-loop yangoku ye-4 ~ 20mA yi-4mA ukumela isignali ye-zero, i-20mA ukumela umlinganiselo opheleleyo wesignali, kunye nomqondiso ongaphantsi kwe-4mA nangaphezulu kwe-20mA isetyenziselwa i-alamu yeempazamo ezahlukeneyo.Imveliso ye-4-20MA yeemveliso zesixhobo seLanrui iyasebenza i-4-20MA isignali ngaphandle kwemitha yamanzi, i-micro flow meter kunye nemitha yokushisa.Imveliso yemitha yamanzi i-4-20mA i-passive.Ngoko ke, xa kusetyenziswa i-4-20mA yombane wamanzi amabini, isixhobo esifumana iimpawu zangoku kufuneka sisebenze. Uthotho lwe-Time Difference: Iimenyu ze-M53-M58 zisetyenziselwa ukulinganisa, ukuseta kunye nokuqinisekisa imveliso ye-4-20MA.

1. Doppler series meter : OUTPUT1 khetha 4-20 mA.I-Flow 4mA isete iFlow ekhawulezileyo ye-4 mA.I-Flow 20mA isete iFlow ekhawulezileyo ye-20mA.Imitha yamanzi / Uluhlu oluncinci lokuhamba: Idijithi yokuqala yemenyu yeCFU imiselwe kwi-2 ukuvula imveliso yangoku.

Iseti yemenyu ye-FF 20mA ukuhambelana nokuhamba kwangoko;I-4mA ibonisa ukuba i-traffic ekhawulezileyo ngu-0 kwaye akukho menyu yokuseta.

2. Imitha yochungechunge lwendawo: kwi-Output submenu, khetha i-4-20 ma kwaye usethe ukuhamba ngokukhawuleza kwe-4 mA kunye ne-20mA.

3. I-Flume kunye ne-weirs thayipha uchungechunge lwe-channel evulekileyo: phantsi kwe-parameter ye-flow Izicwangciso, khetha i-4-20 mA ukuseta ukuhamba ngokukhawuleza kwe-20mA kunye ne-0 ye-4 mA.Akukho menyu yokuseta.
