EVDL-10A Quartz Oscillator Vacuum Gauge
1.Icyegeranyo rusange
EVDL-10A metero ya quartz vacuum ni metero ya vacuum hamwe na quartz kristal oscillator nka sensor.Ifite intera nini kandi yuzuye.Igipimo cya vacuum kigizwe nigice cyo kugenzura no kugenzura, kandi umuyoboro wa digitale wigice cyo kugenzura werekana agaciro kumuvuduko.
2.Ibisobanuro bya tekiniki
1. Gupima intera ： 5 × 10-1-105Pa
2. Amashanyarazi ： AC 220V, 50Hz
3. IMBARAGA ： 7W
4.Ibipimo bya chassis ： 180mm × 80mm × 200mm （L * W * D）
5. Umugozi wuburebure bwa 2m
3.Ihame ry'akazi
EVDL-10A metero ya quartz ya vacuum ni metero ya vacuum ikoresheje ibiranga quartz kristal oscillator resonance impedance hamwe nigitutu cya gaze.Quartz kristal oscillator muri EVDL-10A ya quartz vacuum igipimo ntabwo igizwe na oscillator gusa, ahubwo ni sensor yo gupima umuvuduko wa gaze.Quartz kristal oscillator yashyizwe muri shell ya aluminium kugirango ikore umuyoboro wa gauge ufite diameter ya 15.5mm, ushobora kwinjizwa muri sisitemu ukoresheje interineti.Ibipimo byo gupima inzitizi ya resonance bigaragara mu gishushanyo 1 ：
Igishushanyo 1 Resonant impedance ipima uruziga
Impinduka zidasubirwaho Z = V AB
VABni voltage hejuru ya kristu
Ndi ikigezweho kinyura muri kristu
Ibiriho ndanyura muri ristoriste R mukurikirane hamwe na kristu, na voltage hejuru ya résistor ni VBD
∴ I = V BD
Z = V AB R.
VABni hafi kungana na voltage V.0hakurya ya AC, VBD ihwanye na voltage V.1hakurya ya DC, kandi impedance irashobora kubarwa uhereye kuri V.0, V.1n'indangagaciro.Microcomputer imwe-chip ihindura inzitizi mukibazo, kandi umuyoboro wa digitale werekana agaciro k'umuvuduko.
4.Ibiranga quartz vacuum gauge
Metero ya quartz vacuum irangwa nubunini buke bwa sensor.Ingano yinyeganyeza ya kirisiti ya EVDL-10A metero ya vacuum ya Quartz ni 3.2mm × 1.5mm × 0.8mm.Muri ubu buryo, usibye gupima umuvuduko wa gaze nkizindi metero za vacuum, metero ya vacuum irashobora gupima umuvuduko wa gaze yubunini buke, nkigikoresho cya 1cm3 gifunze, kandi ikamenya leta ifite icyuho.
5.EVDL-10A Kwishyiriraho Quartz vacuum
Kwishyiriraho EVDL-10A quartz vacuum gauge irerekanwa mumashusho 2:
Quartz kristal oscillator hamwe numuzunguruko uzunguruka bishyirwa mubushakashatsi.Umugozi wambere uyobora winjijwe mumurongo winyuma yinyuma yubugenzuzi ukoresheje pine 5, hanyuma umuyoboro ufite diameter ya probe Φ15.5 winjizwa muri sisitemu ya vacuum.Shira umugozi w'amashanyarazi mumwanya winyuma wigice cyigenzura hanyuma ucomeke urundi ruhande mumashanyarazi.Umuyagankuba ugomba kugira insinga zubutaka kugirango uhagarike chassis yubugenzuzi.Fungura amashanyarazi hanyuma igenzure igikoresho cya digitale yerekana agaciro kumuvuduko.Imiyoboro ya Digital yerekana 3.2 E 2 bivuze ko igitutu ari 3.2 × 102Pa.
6.Quartz vacuum gauge kalibrasi
Iyo ubushyuhe bwibidukikije buhindutse, EVDL-10A igomba guhindurwa kuburyo bukurikira:
1. Guhindura ingingo ya Zeru: Nyuma yuko imashini ihagaze neza mugice cyisaha, mugihe umuvuduko uri munsi ya 10-3Pa, kanda buto mumwobo wa zeru kumwanya wambere wikigo gishinzwe kugenzura hamwe na screwdriver kugirango urekure.Niba sisitemu ya vacuum itageze kuri 10-3Pa, buto ya zeru ntishobora gukanda.
2. Amabwiriza ya Atmospheric: Shyira ikirere ku mabwiriza, kanda buto mu mwobo wo mu kirere w’imbere y’igice cy’ubugenzuzi hamwe na screwdriver kugirango urekure.
