Level Transmitter

Mwachidule

DWP-801 fluid level transmitter imapangidwa poyambitsa makina apamwamba a silicon pressure sensor komanso ukadaulo wa DWP Sensors kuchokera ku NOVA Company yaku United States.The apamwamba malo amodzi kuthamanga madzi mlingo kuyeza chida wapambana mutu wa mankhwala zamakono.Amagwiritsidwa ntchito kwambiri poyezera mulingo wamadzimadzi mumafuta amafuta, mafakitale amankhwala, zitsulo, kuteteza chilengedwe, chakudya, kusungirako madzi, madzi am'tawuni, malo amafuta ndi mafakitale ena.Mawonekedwe abwino kwambiri a DWP-801 fluid level transmitter amakwaniritsa zosowa zamafakitale akudziko langa komanso makina opangira ma metering m'mafakitale ena pazida zodziwikiratu zamadzimadzi.

Mawonekedwe

1. Kukhazikika kwabwino, kulondola kwambiri, kuchuluka kwa magwiridwe antchito / mtengo

2. Ikani mwachindunji mu sing'anga yoyezera, yosavuta kukhazikitsa ndikugwiritsa ntchito

3. Mapangidwe olimba, opanda magawo osuntha, kudalirika kwakukulu, moyo wautali wautumiki

4. Muyezo wolondola kwambiri ukhoza kuchitidwa kuchokera m'madzi, mafuta kuti muyike ndi kukhuthala kwakukulu, ndipo sikungakhudzidwe ndi thovu, kuyika ndi mawonekedwe amagetsi a sing'anga yoyezera.

5. Palibe kutopa kwakuthupi kumavala, osamva kugwedezeka ndi kukhudzidwa

6. Ndi mphamvu reverse polarity chitetezo ndi overload panopa kuchepetsa chitetezo

Mfundo yogwira ntchito

Mfundo yoyezera ndi static pressure

Pamene transmitter yamadzimadzi imayikidwa mukuzama kwina mumadzimadzi omwe amayezedwa, kukakamiza kwamadzimadzi pa sensa ndi P=ρ.g.H+PO;

P: Kupanikizika pamadzimadzimadzi a sensa Bit nkhosa: Pa

ρ: kachulukidwe ka madzi oti ayezedwe, unit: kg/m³

g: kuthamanga kwamphamvu yokoka, gawo: m/s²

Po: Kuthamanga kwa mumlengalenga pamtunda wamadzimadzi, unit: Pa

H: Kuzama kwamadzimadzi komwe kumatsitsidwa ndi sensor Unit: m

Panthawi imodzimodziyo, kuthamanga kwa mumlengalenga PO pamtunda wamadzimadzi kumalowetsedwa m'chipinda cham'mbuyo cha sensa kudzera mu chingwe chowongolera mpweya, ndipo PO pamadzimadzi imamveka pamtunda wochepa, kotero kuti kuthamanga kwake kumayesedwa ndi sensor ndi:

P = 0.gH Mwachiwonekere, poyeza kuthamanga kwa P, kuya kwa madzi amadzimadzi H kungapezeke, ndipo chizindikiro cha kuthamanga chomwe chimamveka ndi sensa chimasinthidwa ndikukulitsidwa ndi dera, ndiyeno chimatulutsa ngati chizindikiro chokhazikika pambuyo polipidwa.
