WP401A yakajairwa maindasitiri ekumanikidza transmitter, kusanganisa epamberi ekunze sensor zvinhu zvine solid-state kubatanidzwa uye yekuzviparadzanisa diaphragm tekinoroji, yakagadzirirwa kushanda isina musono mumamiriro akasiyana siyana, ichiita sarudzo inogoneka uye yakavimbika kune akasiyana maindasitiri ekushandisa.
Iyo geji uye yakakwana yekumanikidza transmitter ine akasiyana-siyana ekubuda masaini anosanganisira 4-20mA (2-waya) uye RS-485, uye yakasimba anti-kupindira kugona kuve nechokwadi cheyero uye inowirirana. Yayo aluminium imba uye junction bhokisi inopa kusimba uye dziviriro, nepo sarudzo yenzvimbo yekuratidzira inowedzera nyore uye kuwanikwa.
