EVDL-10A quartz vacuum mita bụ oghere oghere emere site na iji njirimara nke quartz crystal oscillator resonance impedance na nrụgide gas.Quartz crystal oscillator na EVDL-10A quartz vacuum gauge abụghị naanị akụkụ nke oscillator, kamakwa ihe mmetụta maka ịlele nrụgide gas.A na-etinye oscillator quartz kristal na shei aluminom iji mee ọkpọkọ nlele na dayameta nke 15.5mm, nke enwere ike itinye ya na sistemụ site na interface.Egosiri sekit nleta nke impedance resonance na eserese 1:

Ọgụgụ 1 sekit nlele impedance resonant

Resonant impedance Z=V AB

V_ABbụ voltaji gafee kristal

M bụ ugbu a na-eru na kristal

Ugbu a I na-aga site na resistor R n'usoro ya na kristal, voltaji gafee resistor bụ VBD

∴ I = V BD

Z=V AB R

V_ABhà nhata na voltaji V₀n'ofe AC, VBD hà nhata na voltaji V₁gafee DC, enwere ike gbakọọ ihe mgbochi ahụ site na V tụrụ atụ₀, V₁na ụkpụrụ nguzogide.Igwe kọmputa nke otu mgbawa na-atụgharị ihe mgbochi ka ọ bụrụ nrụgide, na tube dijitalụ na-egosiputa uru nrụgide.

4.Njirimara nke quartz vacuum gauge

A na-eji obere olu ihe mmetụta mara quartz vacuum mita.Ogo ịma jijiji kristal nke EVDL-10A quartz vacuummeter bụ 3.2mm × 1.5mm × 0.8mm.N'ụzọ dị otú a, na mgbakwunye na ịlele nrụgide gas dị ka mita ndị ọzọ na-ekpo ọkụ, igwe na-ekpo ọkụ nwere ike ịlele nrụgide gas nke obere olu, dị ka ngwaọrụ 1cm3 nke agbachiri, wee chọpụta ọnọdụ nkwụsị ọkụ.

5.EVDL-10A Quartz oghere nlele nwụnye

E gosipụtara ntinye nke EVDL-10A quartz vacuum gauge na foto 2:

A na-etinye oscillator kristal quartz na sekit oscillating na nyocha.A na-etinye eriri ndu n'ime oghere nke azụ azụ nke njikwa njikwa site na nkwụnye 5-pin, na ọkpọkọ nke nwere dayameta nke nyocha Φ15.5 na-etinye n'ime usoro oghere.Tinye eriri ọkụ n'ime oghere azụ azụ nke ngalaba njikwa wee gbanye nsọtụ nke ọzọ n'ime oghere ọkụ.Oghere ọkụ kwesịrị inwe waya ala iji gbatuo chassis njikwa.Gbanyụọ ọkụ ọkụ na ihe njikwa akara dijitalụ na-egosiputa uru nrụgide.Ngosipụta tube dijitalụ 3.2 E 2 pụtara uru nrụgide bụ 3.2 × 102Pa.

6.Quartz agụụ nlele calibration

Mgbe ọnọdụ okpomọkụ na-agbanwe, EVDL-10A kwesịrị ịhazi ya dị ka ndị a:

1. Ndozi ihe efu: Mgbe igwe kwụsiri ike ruo ọkara elekere, mgbe nrụgide na-erughị 10-3Pa, pịa bọtịnụ na oghere efu nke n'ihu panel nke njikwa njikwa na screwdriver iji hapụ ya.Ọ bụrụ na usoro agụụ anaghị eru 10-3Pa, enweghị ike ịpị bọtịnụ efu.

2. Usoro ikuku: Kpochapụ ikuku na ụkpụrụ ahụ, pịa bọtịnụ na oghere ikuku nke ihu panel nke njikwa njikwa na ihe nkedo iji hapụ ya.
