Chiyambi cha kutulutsa kwa 4-20mA

Mamita ambiri a mafakitale amasankha kugwiritsa ntchito mphamvu yamagetsi potumiza zizindikiro, chifukwa mphamvu yamagetsi siimva phokoso. Chizunguliro chamagetsi cha 4 ~ 20mA ndi 4mA kuyimira chizindikiro cha zero, 20mA kuyimira sikelo yonse ya chizindikirocho, ndipo chizindikiro chomwe chili pansi pa 4mA ndi pamwamba pa 20mA chimagwiritsidwa ntchito pochenjeza zolakwika zosiyanasiyana. Mphamvu ya 4-20MA ya zinthu za Lanrui ndi yogwira ntchito ya 4-20MA kupatula mita yamadzi, mita yamagetsi yaying'ono ndi mita yotenthetsera. Mphamvu ya mita yamadzi ya 4-20mA ndi yopanda ntchito. Chifukwa chake, pamene mphamvu ya 4-20mA ya mita yamadzi ya waya ziwiri ikugwiritsidwa ntchito, chipangizo cholandira zizindikiro zamagetsi chiyenera kukhala chogwira ntchito.  Mndandanda wa Kusiyana kwa Nthawi: Mamenyu a M53-M58 amagwiritsidwa ntchito poyesa, kukhazikitsa ndikutsimikizira mphamvu ya 4-20MA.

1. Doppler series meter: OUTPUT1 sankhani 4-20 mA. Flow 4mA ikani nthawi yomweyo Flow ya 4 mA. Flow 20mA ikani nthawi yomweyo Flow ya 20mA. Water meter/Small flow series: Manambala oyamba a menyu ya CFU ayikidwa pa 2 kuti ayatse mphamvu yamagetsi.

Menyu ya FF yakhazikitsidwa 20mA kuti igwirizane ndi kayendedwe ka nthawi yomweyo; 4mA imasonyeza kuti kuchuluka kwa magalimoto nthawi yomweyo ndi 0 ndipo palibe menyu yoti ikhazikitsidwe.

2. Chiyeso cha liwiro la dera: mu submenu ya Output, sankhani 4-20 ma ndikukhazikitsa kuyenda kwa 4 mA ndi 20mA nthawi yomweyo.

3. Flume ndi ma weirs mtundu wotseguka wa njira: pansi pa mayendedwe a parameter Zokonda, sankhani 4-20 mA kuti muyike mayendedwe a 20mA nthawi yomweyo ndi 0 pa 4 mA. Palibe menyu yoti muyike.
