4-20mA kuburitswa kwemhedzisiro

Mamita mazhinji emaindasitiri anosarudza kushandisa magetsi emagetsi kutumira masaini, nekuti magetsi haanzwi ruzha. Chinotenderera chemagetsi che4 ~ 20mA i4mA chinomiririra chiratidzo chezero, 20mA chinomiririra chiyero chose chechiratidzo, uye chiratidzo chiri pasi pe4mA nepamusoro pe20mA chinoshandiswa kurira kwezvikanganiso zvakasiyana-siyana. 4-20MA inobuda muzvigadzirwa zveLanrui instrument products inoshanda 4-20MA signal kunze kwewater meter, micro flow meter uye heat meter. Kubuda kwewater meter 4-20mA hakushande. Saka, kana 4-20mA inobuda muwaya yemvura yewaya mbiri ichishandiswa, mudziyo unogamuchira magetsi emagetsi unofanirwa kunge uchishanda.  Nguva yeMusiyano: Menyu yeM53-M58 inoshandiswa kugadzirisa, kugadzirisa uye kusimbisa 4-20MA inobuda.

1. Doppler series meter: OUTPUT1 sarudza 4-20 mA. Flow 4mA isa Flow instantly ye 4 mA. Flow 20mA isa Flow instantly ye 20mA. Water meter/Small flow series: Nhamba yekutanga yemenyu yeCFU yakaiswa pa 2 kuti ivhure current output.

Menyu yeFF yakaiswa 20mA kuti ienderane nekuyerera kwepakarepo; 4mA inoratidza kuti traffic inokurumidza iri 0 uye hapana menyu yekuisa.

2. Chiyero chemuchina wekumhanya kwenzvimbo: muchikamu cheOutput, sarudza 4-20 ma woisa kuyerera kwe4 mA ne20mA ipapo ipapo.

3. Flume ne weirs type open channel series: pasi pe flow parameter Settings, sarudza 4-20 mA kuti uise flow instantly ye 20mA uye 0 ye 4 mA. Hapana menyu yekuisa.
