Iinkcukacha zeMveliso

Iithegi zeMveliso

Iiparamitha ezisebenzayo:
1. Ubungakanani bokusetyenziswa: ulwelo, igesi kunye nomphunga.
2. Imveliso yomqondiso: i-wire system ezimbini 4 ~ 20mA eyedwa ye-DC isignali ephakanyisiweyo ye-HART ye-digital output, i-linear okanye i-square root output ingakhethwa, ubuninzi bemveliso yangoku ayikho ngaphezu kwe-22mA.
3. Umbane wombane: DC 12 ~ 45V;Unxibelelwano lwe-HART, uluhlu lwamandla ombane: 15.5 ~ 45V DC;Amandla ombane okusebenza ngokubanzi: 24V DC.
