Sei 4 ~ 20mA 2-waya Ichiita Mainstream Output yeTransmitter

Nekuremekedza kutapurirana chiratidzo chekufambisa mumaindasitiri otomatiki maapplication, 4 ~ 20mA ndeimwe yesarudzo yakajairika. Muchiitiko chacho pachave nehukama hwemutsara pakati pekuchinja kwemaitiro (kumanikidza, nhanho, tembiricha, nezvimwewo) uye zvazvino kubuda. 4mA inomiririra yakaderera muganho, 20mA inomiririra yepamusoro muganho, uye renji span i16mA. Ndeapi marudzi emabhenefiti anosiyanisa 4 ~ 20mA kubva kune mamwe azvino uye magetsi anobuda uye ave akakurumbira zvakadaro?

Azvino uye voltage ese ari maviri anoshandiswa pakufambisira masaini emagetsi. Nekudaro chiratidzo chazvino chinofarirwa kupfuura voltage mune zvekushandisa. Chimwe chechikonzero chikuru ndechekuti nguva dzese kubuda kwazvino kashoma kukonzeresa kudonha kwevoltage pamusoro pekutapurirana kwakareba sezvo ichikwanisa kukwidza voltage yekutyaira kutsiva kutapurirana. Zvichakadaro, zvichienzaniswa nechiratidzo chevoltage, yazvino inoratidza hukama hwakanyanya mutsara nemaitiro akasiyana ayo anobatsira kune yakareruka calibration uye muripo.

Mheni Dziviriro Kunyudza Level Transmitter, 4 ~ 20mA 2-waya

Mukupesana nedzimwe chiyero chemazuva ese chechiratidzo (0 ~ 10mA, 0 ~ 20mA nezvimwewo) chinhu chikuru che 4 ~ 20mA ndechekuti haisarudze 0mA semuganho wakaderera wekuyera renji. Chirevo chekukwira zero sikero kune mhenyu kubata nedambudziko razero rakafa zvinoreva kusakwanisa kuona kusashanda kwehurongwa kunokonzera kutadza kunounza kuburitsa kwe0mA kusingazivikanwe kana chiyero chepasi chiri zvakare 0mA. Kana iri 4 ~ 20mA chiratidzo, kuputsika kwaigona kujekeswa nekudonha kwazvino kudonha pasi pe4mA sezvo yaisazoonekwa seyakayerwa kukosha. 

4 ~ 20mA Differential Pressure Transmitter, rarama zero 4mA

Pamusoro pezvo, iyo 4mA yakaderera muganho inovimbisa kushoma inodiwa simba rekushandisa kushandisa chiridzwa nepo 20mA yepamusoro muganho inorambidza kukuvara kunouraya kumuviri wemunhu nezvikonzero zvekuchengetedza. 1: 5 reshiyo reshiyo inoenderana neyakajairwa pneumatic control system inobatsira pakuverenga kuri nyore uye dhizaini iri nani. Yazvino loop-powered 2-waya ine yakasimba ruzha yekudzivirira yakanakira kuisirwa.

Aya mabhenefiti mune ese maficha anowanzoita 4-20mA imwe yeanonyanya kuenderana chiridzwa kuburitsa mu process control automation. Shanghai WangYuan ari pamusoro 20 makore chiridzwa mugadziri. Isu tinopa zviridzwa zvakatanhamara ne4-20mA kana imwe yakasarudzika yekubuda sarudzo dzepressure, level, tembirichauyekuyereracontrol.
