Muindasitiri ye otomatiki, isu tinowanzonzwa mazwi geji kudzvanywa uye mhedziso kudzvanywa.Saka chii chinonzi gauge pressure uye absolute pressure?Ndeupi musiyano uripo pakati pavo?Nhanganyaya yekutanga imhepo yemhepo.
Atmospheric pressure: Kudzvinyirirwa kwechikamu chemhepo chiri pamusoro penyika nekuda kwegiravhiti.Izvo zvinoenderana nekukwirira, latitude uye meteorological mamiriro.
Differential pressure (differential pressure)
Musiyano uripo pakati pemamanikidziro maviri.
Absolute pressure
Madzvinyiriro ese ari munzvimbo iyo svikiro (mvura, gasi kana chipfunga) chiripo.Absolute pressure ndiyo pressure inoenderana ne zero pressure.
Gauge pressure (relative pressure)
Kana mutsauko uripo pakati pekumanikidza kwakazara uye kumanikidzwa kwemhepo kuri kukosha kwakanaka, saka iyi yakanaka kukosha ndeye geji pressure, kureva, gauge pressure = absolute pressure-atmospheric pressure> 0.
Mumataurirwo anoitwa vanhuwo zvavo, magauji akajairwa anoyera geji, uye mhepo yemuchadenga isimba chairo.Pane absolute pressure geji yekuyeresa pressure yese.
Tora kumanikidza panzvimbo mbiri dzakasiyana pane pombi.Musiyano uripo pakati pemakumanikidza maviri ndiko kudzvanywa kwekusiyanisa.Iyo general differential pressure transmitter inoyera iyo differential pressure.
