Chii Chinoitika Kana Ukadarika Maitiro Ekutevedzera Matambo Ekushandisa Instrumentation?
- Mhinduro Yakananga: Kusatevedzera Mutemo Kunodhura Uye Kune Ngozi
Vanhu vanogara vachibvunza kuti:"Sei kutevedzera mitemo yetambo dzemidziyo yemagetsi kuchikosha kudaro?"
Mhinduro iri nyore:Ruzivo rweindasitiri runoratidza kuti80% yemidziyo isingatevedzere mitemo yekuisa tambo inosangana nematambudziko makuru mukati memwedzi gumi nemisere- kubva pakukanganisa kwezviratidzo nguva nenguva kusvika pakukundikana kwesystem zvachose uye njodzi dzemoto.
| Chikamu cheMhedzisiro | Mhedzisiro Yakananga | Mhedzisiro Yakajairika Yemutengo |
| Kutendeseka kwechiratidzo | Kuverengwa kwe4-20mA kusina kurongeka, zvikanganiso zvekutaurirana zveRS485, thermocouple drift | Kukanganiswa kwemaitiro, chigadzirwa chisina kutsanangurwa, kugadzirisa patsva |
| Kukundikana kwemidziyo | Maseketi mapfupi, zvikanganiso zvepasi, kuputsika kwekudzivirira | Nguva yekuzorora isina kurongwa ($10,000-$500,000/awa) |

Pfungwa Yechokwadi:Kusiya kutevedzera mitemo yemumba kuti uchengetedze 10-20% pamutengo wetambo kunowanzo konzeraMutengo wose wakakwira ne10-100 ×kana kukundikana, nguva yekushanda, uye kugadzirisa patsva zvichitariswa.
(20% chete yezvishandiso zvinoenderana nemutemo zvinobudirira nepo zvimwe zvichikundikana mukati memwedzi gumi nemisere)
PaDingzun Cable,Tambo dzedu dzese dzekushandisa dzinoenderana zvizere neEN 50288-7, IEC 60332, uye zvinodiwa neNEC/CE zvinoshanda - nemagwaro ekuongorora akanyorwa kuti aratidze izvozvo. Kutevedzera mitemo hakusi sarudzo; ndiyo mwero wedu.
- Data: 80% Kukundikana Kwekusatevedzera Mutemo
Zvidzidzo zveindasitiri nedata remumunda zvinoratidza nguva dzose kuti tambo dzisingateereri mitemo dzinokundikana nemitengo yakakwira zvikuru.
Tafura 1: Kutevedzera Mutemo vs Kusatevedzera Mutemo - Kuenzanisa Kwemari Yekukundikana
| Paramita | Tambo Inoenderana Nezvinodiwa (EN 50288-7, UL, IEC) | Cable Isina Kutevedzera / Yakajairika |
