Kufalikira kwa silicon pressure transmitter

Mwachidule

Ma transmitters a DWP-802 mndandanda amapangidwa mwapadera ndikupangidwa kuti azigwiritsidwa ntchito poyesa kukakamiza kwa mafakitale, komwe magwiridwe antchito amakhala wamba.Mndandanda wazinthuzi umagwiritsa ntchito ukadaulo wopangira makina opangira mphamvu yaku Germany.Wopangidwa ndi sensa ya ceramic, makina ophatikizika kwambiri amagetsi ndi chipolopolo chachitsulo chosapanga dzimbiri, ali ndi mawonekedwe ang'onoang'ono, kulondola kwapamwamba, kusokoneza kwakukulu kwa anti-electromagnetic, kukhazikitsa kosavuta ndikusintha, komanso kulimba.

Mawonekedwe aukadaulo

■ Awiri-waya dongosolo linanena bungwe 4-20mA

■ Mulingo wapakatikati umagwirizana ndi DNI6 128

■ Okonzeka ndi diffused silicon pressure sensor:

- Palibe makina otayirira

kukhazikika kwanthawi yayitali

- Kubwereza kwabwino

■ Kupanikizika kochulukira ndi 2 ~ 4 nthawi zoyezera zonse

■Stainless zitsulo nembanemba ndi zosapanga dzimbiri ndondomeko kugwirizana

■ Chipolopolo chachitsulo chosapanga dzimbiri, kalasi yachitetezo 1P65 ndi EP68

■ Kutha kwamphamvu kwa anti-electromagnetic interference

■ Otetezeka kwenikweni

Mfundo yogwira ntchito

Sensor yokakamiza ya mndandanda wa DWP-802 ndi mlatho wokhazikika wa silicon cathode wopangidwa ndi vacuum-depositing semiconductor pamwamba pa silicon substrate.Pali chinsalu chachitsulo chosapanga dzimbiri chamalata pakati pake ndi sing'anga yoyezera, ndipo mafuta ophatikizira amadzimadzi a silicone amadzazidwa pakati pa mlatho wa strainer ndi pepala lamalata osapanga dzimbiri.

Pamene kuthamanga P imagwira ntchito pa pepala lamalata ndipo imafalikira ku mlatho wovutitsa kudzera m'madzi apakati, kusintha kwa cathode ya mlatho kumapangitsa kuti mlathowo ukhale wabwinoko ndi ma siginoloji angapo olingana ndi kuthamanga kwa P. Kenako, amasinthidwa kukhala 4. -20mA linanena bungwe ndi kutembenuka kwa siginecha ndi amplification dera ndi kutentha chipukuta misozi.
