4-20mA zotulutsa zoyambira

Mamita ambiri ogulitsa mafakitale amasankha kugwiritsa ntchito zamakono kuti atumize zizindikiro, chifukwa zamakono sizimva phokoso.Lupu lamakono la 4 ~ 20mA ndi 4mA kuimira chizindikiro cha zero, 20mA kuyimira sikelo yonse ya chizindikiro, ndipo chizindikiro chomwe chili pansi pa 4mA ndi pamwamba pa 20mA chimagwiritsidwa ntchito pa alamu ya zolakwika zosiyanasiyana.The 4-20MA linanena bungwe Lanrui chida mankhwala yogwira 4-20MA chizindikiro kupatula madzi mita, micro otaya mita ndi kutentha mita.Kutulutsa kwa mita yamadzi 4-20mA sikungokhala.Choncho, pamene kutulutsa kwa 4-20mA kwa mita ya madzi a waya awiri kumagwiritsidwa ntchito, chipangizo cholandira zizindikiro zamakono chiyenera kukhala chogwira ntchito. Mndandanda wa Kusiyana kwa Nthawi: Ma menyu a M53-M58 amagwiritsidwa ntchito poyesa, kukhazikitsa ndi kutsimikizira kutulutsa kwa 4-20MA.

1. Doppler mndandanda wa mita : OUTPUT1 sankhani 4-20 mA.Flow 4mA imayika Kuyenda pompopompo kwa 4 mA.Flow 20mA imayika Flow nthawi yomweyo kwa 20mA.Mamita amadzi / Mayendedwe ang'onoang'ono: Nambala yoyamba ya menyu ya CFU imayikidwa ku 2 kuti mutsegule zomwe zikuchitika.

FF menyu yokhazikitsa 20mA kuti igwirizane ndi kutuluka kwanthawi yomweyo;4mA ikuwonetsa kuti kuchuluka kwa magalimoto nthawi yomweyo ndi 0 ndipo palibe menyu oti muyike.

2. Area-velocity series mita: mu Output submenu, sankhani 4-20 ma ndikukhazikitsa nthawi yomweyo 4 mA ndi 20mA.

3. Flume ndi weirs lembani mndandanda wotsegulira njira: pansi pa kayendedwe ka kayendedwe ka kayendedwe kake, sankhani 4-20 mA kuti muyike nthawi yomweyo 20mA ndi 0 kwa 4 mA.Palibe menyu oti muyike.
