EVDL-10A Quartz Oscillator Vacuum Gauge

1.Tirohanga hua

EVDL-10A quartz vacuum mita he mita korehau ki te kiripaka oscillator karaihe rite pūoko.He awhe whanui me te tino tika.Ko te ine korehau kei roto he ture me te wae whakahaere, a ko te ngongo matihiko o te waahanga whakahaere e whakaatu ana i te uara pehanga.

2. Nga whakaritenga hangarau

1. Awhe ine: 5×10-1-105Pa

2. Tuku Hiko: AC 220V,50Hz

3. MANA：7W

4.Ahu tauhu:180mm×80mm×200mm（L*W*D）

5. Te roa o te taura 2m

3.Maataapono mahi

EVDL-10A quartz vacuum mita he mita korehau i hangaia ma te whakamahi i nga ahuatanga o te quartz crystal oscillator resonance impedance me te pehanga hau.Ko te oscillator tioata kiripaka i roto i te EVDL-10A quartz vacuum gauge ehara i te mea he waahanga noa iho o te oscillator, engari he pūoko mo te ine i te pehanga hau.Ka whakauruhia te oscillator tioata kiripaka ki roto i te anga konumohe hei hanga paipa mehua me te diameter o te 15.5mm, ka taea te whakauru ki roto i te punaha ma te atanga.Ko te iahiko ine o te impedance resonance e whakaatuhia ana i te Whakaahua 1:

Whakaahua 1 Iahiko ine ine ine ine

Resonant impedance Z= V AB

V_ABko te ngaohiko puta noa i te karaihe

Ko ahau te ia e rere ana i roto i te karaihe

Ka rere ahau i roto i te parenga R i roto i te raupapa me te karaihe, a ko te ngaohiko puta noa i te parenga ko VBD

∴ I = V BD

Z=V AB R

V_ABhe rite tonu ki te ngaohiko V₀puta noa i te AC, he rite tonu te VBD ki te ngaohiko V₁puta noa i te DC, ka taea te tatau te impedance mai i te inenga V₀, V₁me nga uara parenga.Ko te miihini miihini kotahi-marama ka huri te impedance ki te pehanga, ka whakaatu te ngongo matihiko i te uara pehanga.

4. Nga ahuatanga o te ine korehau kiripaka

Ko te mita korehau kiripaka e tohuhia ana e te rōrahi pūoko iti.Ko te rahi o te wiri karaihe o EVDL-10A quartz vacuum mita he 3.2mm × 1.5mm × 0.8mm.I tenei ara, i tua atu i te ine i te pehanga hau pera i etahi atu mita korehau, ka taea e te mita korehau te ine i te pehanga hau o te rōrahi iti, penei i te taputapu hiri 1cm3 te rahi, me te kite i te ahua pupuri korehau.

5.EVDL-10A Quartz marua mehua whakaurunga

Ko te whakaurunga o te EVDL-10A quartz vacuum gauge e whakaatuhia ana i te Whakaahua 2:

Ko te oscillator tioata kiripaka me te iahiko oscillating ka tuu ki roto i te rangahau.Ka whakauruhia te taura arataki ki roto i te turanga o te papa o muri o te waahanga whakahaere ma te mono 5-pin, ka whakauruhia te paipa me te diameter o te tirotiro Φ15.5 ki roto i te punaha korehau.Monohia te taura hiko ki te turanga paewhiri o muri o te wae whakahaere, ka honoa tetahi pito ki te putanga hiko.Me whai waea whenua te putanga hiko ki te whakamau i te tahuhu wae whakahaere.Whakakāhia te whakakā hiko ka whakaatu te ngongo matihiko waeine whakahaere i te uara pehanga.Ko te whakaaturanga ngongo matihiko 3.2 E 2 te tikanga ko te uara pehanga he 3.2×102Pa.

6.Quartz korehau mehua te whakatikatika

Ka huri te pāmahana ambient, me whakarite te EVDL-10A penei:

1. Te whakatikatika tohu kore: I muri i te noho pumau o te miihini mo te hawhe haora, ka iti iho te pehanga i te 10-3Pa, pehia te paatene i roto i te kohao kore o te papa o mua o te waahanga whakahaere me te huriwiri ki te tuku.Ki te kore e eke te punaha korehau ki te 10-3Pa, kaore e taea te pehi i te paatene kore.

2. Te ture o te hau: Whakaatuhia te hau ki te ture, pehia te patene i roto i te kohao hau o te papa o mua o te waahanga whakahaere me te huriwiri hei tuku.
