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

Nezvekutumira masaini ekutumira mukushandiswa kwemagetsi muindasitiri, 4~20mA ndiyo imwe yesarudzo dzakajairika. Kana paine hukama hwakatarwa pakati pekuchinja kwemaitiro (kumanikidzwa, mwero, tembiricha, nezvimwewo) uye kubuda kwemagetsi. 4mA inomiririra muganho wakaderera, 20mA inomiririra muganho wepamusoro, uye kureba kwenzvimbo i16mA. Ndezvipi zvinobatsira zvinosiyanisa 4~20mA kubva kune mamwe magetsi emagetsi nemagetsi uye zvinova zvakakurumbira?

Magetsi nemagetsi zvese zvinoshandiswa pakutumira masaini emagetsi. Zvisinei, masaini emagetsi anonyanya kufarirwa kupfuura magetsi mukushandiswa kwemidziyo. Chimwe chezvikonzero chikuru ndechekuti magetsi anoramba achibuda haawanzo kukonzera kudzikira kwemagetsi panguva yekutumira masaini ari kure sezvo achikwanisa kukwidza voltage yekutyaira kuti adzore kudonha kwemagetsi. Zvichakadaro, kana tichienzanisa nemagetsi, magetsi anoratidza hukama hwakanyatsorongeka nemaitiro akasiyana-siyana anobatsira pakugadziriswa uye kubhadharwa zviri nyore.

Chinotapurirana Chekudzivirira Mheni, 4~20mA ine waya mbiri

Kusiyana nezvimwe zviyero zvemagetsi zvenguva dzose (0~10mA, 0~20mA nezvimwewo), chinhu chikuru che4~20mA ndechekuti haisarudze 0mA semuganho wakaderera wekuyera. Chikonzero chekukwidza chiyero chezero kuita chiri mupenyu ndechekugadzirisa dambudziko re dead zero zvinoreva kuti kusakwanisa kuona kusashanda zvakanaka kwesystem kunokonzera kukundikana kunotungamira ku 0mA output isingazivikanwe kana chiyero chemagetsi chenguva yakaderera chiriwo 0mA. Kana iri chiratidzo che4~20mA, kuputsika kunogona kuzivikanwa zvakajeka nekudonha kwemagetsi zvisina kujairika pasi pe4mA sezvo isingazotariswe semutengo wakayerwa. 

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

Pamusoro pezvo, muganho wepasi we4mA unovimbisa kushandiswa kwesimba shoma rinodiwa kuti mudziyo ushande nepo muganho wepamusoro we20mA uchidzivirira kukuvara kunouraya muviri wemunhu nekuda kwezvikonzero zvekuchengetedza. 1:5 range ratio inoenderana netsika yekudzora pneumatic inobatsira pakuverenga zviri nyore uye dhizaini iri nani. 2-waya dzinoshanda neluop dzazvino dzine dziviriro yakasimba yeruzha uye dziri nyore kuisa.

Mabhenefiti aya muzvinhu zvese anoita kuti 4-20mA ive imwe yemidziyo inoshandiswa zvakanyanya mukugadzira otomatiki. Shanghai WangYuan ikambani inogadzira michina kwemakore anopfuura makumi maviri. Tinopa michina yakanaka ine 4-20mA kana dzimwe sarudzo dzemichina yakagadzirirwa.kumanikidzwa, danho, tembirichauyekuyererakudzora.
