EVDL-10A Quartz Oscillator Vacuum Gauge

1. Dulmarka alaabta

EVDL-10A quartz vacuum meter waa mitirka faakuumka leh oscillator quartz crystal oscillator ahaan.Waxay leedahay kala duwanaansho ballaaran iyo saxnaan sare.Qiyaasta faakuumka waxay ka kooban tahay nidaam iyo unug xakameyn, iyo tuubada dhijitaalka ah ee cutubka kantaroolku waxay soo bandhigaysaa qiimaha cadaadiska.

2. Tilmaamaha farsamada

1. Cabbirka cabbirka: 5×10-1-105Pa

2. Korontada: AC 220V,50Hz

3.Awoodda:7W

4. Cabbirrada Chassis: 180mm × 80mm × 200mm (L * W * D)

5. Dhererka fiilada 2m

3.Mabda'a shaqada

EVDL-10A quartz vacuum meter waa mitirka faakuumka ee la sameeyay iyadoo la adeegsanayo sifooyinka is-daba-marineed ee quartz crystal oscillator iyo cadaadiska gaaska.Quartz crystal oscillator ee EVDL-10A quartz vacuum gauge ma aha oo kaliya qayb ka mid ah oscillator, laakiin sidoo kale waa dareeraha lagu cabbiro cadaadiska gaaska.Quartz crystal oscillator waxaa lagu rakibay qolof aluminium si loo sameeyo tuubo cabbir leh dhexroor 15.5mm, kaas oo la geliyo nidaamka iyada oo loo marayo interface.Wareegga cabbiraadda ee impedance resonance waxa lagu muujiyay sawirka 1:

impedance resonant Z=V AB

V_ABwaa danab guud ahaan crystal

Anigu waa kan hadda socda ee crystal-ka

Hadda I waxay ku socotaa iska caabin R si taxane ah oo leh crystal, iyo korantada guud ahaan iska celiyaha waa VBD

∴ I = V BD

Z=V AB R

V_ABwaxa uu qiyaas ahaan le'eg yahay danabka V₀guud ahaan AC, VBD waxay la mid tahay korantada V₁guud ahaan DC, iyo caqabada waxaa laga xisaabin karaa cabbirka V₀, V₁iyo qiimaha iska caabinta.Microcomputer-ka hal-chip-ka ah wuxuu u beddelaa xannibaadda cadaadis, iyo tuubada dhijitaalka ah waxay muujinaysaa qiimaha cadaadiska.

4. Astaamaha quartz vacuum gauge

Mitirka faakuumka quartz waxaa lagu gartaa mugga dareemayaasha yar.Cabbirka gariirka crystal ee EVDL-10A quartz vacuum meter waa 3.2mm × 1.5mm × 0.8mm.Sidan, marka lagu daro cabbiraadda cadaadiska gaaska sida mitirka faakuumka kale, mitirka vacuumku wuxuu cabbiri karaa cadaadiska gaaska mug yar, sida cabbirka 1cm3 ee la xidhay, oo wuxuu ogaan karaa xaaladda haynta vacuum.

5.EVDL-10A Quartz vacuum gauge rakibida

Rakibaadda EVDL-10A quartz vacuum gauge waxa lagu muujiyay sawirka 2:

Oscillator-ka quartz crystal oscillator iyo wareegga oscillating ayaa lagu dhejiyaa baaritaanka.Xadhkaha rasaasta ayaa la geliyaa godka dambe ee qaybta kontoroolka iyada oo loo marayo fur 5-pin ah, iyo tuubada leh dhexroorka baaritaanka Φ15.5 ayaa la geliyaa nidaamka faakuumka.Ku xidh fiilada korontada godka dambe ee unugga kantaroolka oo ku xidh cidhifka kale meel koronto ah.Korontadu waa inay lahaataa silig dhulka ah si ay u dejiso qaybta xakamaynta.Daar furaha korontada oo cutubka kantaroolka tuubada dhijitaalka ah ayaa soo bandhigaysa qiimaha cadaadiska.Muujinta tuubada dhijitaalka ah 3.2 E 2 macnaheedu waa qiimaha cadaadiska waa 3.2 × 102Pa.

6.Quartz vacuum calibration calibuum

Marka heerkulka deegaanku is beddelo, EVDL-10A waa in loo cabbiraa sida soo socota:

1. Isku-habeynta eber: Ka dib marka mashiinku uu xasilloon yahay nus saac, marka cadaadiska uu ka yar yahay 10-3Pa, riix badhanka godka eber ee qaybta hore ee cutubka kantaroolka oo leh furaha si uu u sii daayo.Haddii nidaamka faakuumku aanu gaadhin 10-3Pa, badhanka eber lama riixi karo.

2. Nidaaminta jawiga: U soo bandhig jawiga nidaamka, riix batoonka godka atmospheric ee guddida hore ee unugga kantaroolka oo leh biro si loo sii daayo.
