Ihame ry'akazi

Amashanyarazi ya CET-DQ601B agizwe nicyiciro cyo guhindura ibyiciro, icyiciro cyo guhuza n'imihindagurikire y'ikirere, akayunguruzo gato, akayunguruzo gakomeye, imbaraga za nyuma zongerewe imbaraga hamwe n'amashanyarazi.Th :
1) .Kwishyuza icyiciro cyo guhindura: hamwe na amplifier ikora A1 nkibanze.
Amashanyarazi ya CET-DQ601B arashobora guhuzwa na sensor ya piezoelectric yihuta, sensor ya piezoelectric sensor na sensor ya piezoelectric.Ibisanzwe biranga ni uko ingano yubukanishi ihindurwamo intege nke Q iringaniza nayo, kandi ibyasohotse impedance RA ni ndende cyane.Icyiciro cyo guhindura icyiciro ni uguhindura amafaranga muri voltage (1pc / 1mV) ihwanye no kwishyurwa no guhindura impedance yo hejuru ikaboneka mubisohoka bike.
Ca --- Ubushobozi bwa sensor mubusanzwe ni ibihumbi byinshi PF, 1/2 π Raca igena umuvuduko muke muto wa sensor.

Cc-- Sensor isohora amajwi make ya capacitance.
Ci - Kwinjiza ubushobozi bwa amplifier ikora A1, agaciro gasanzwe 3pf.
Icyiciro cyo guhindura icyiciro A1 gikoresha Abanyamerika mugari-Precision Operational Amplifier hamwe ninjiza nyinshi, urusaku ruke na drift.Ubushobozi bwo gusubiza CF1 ifite inzego enye za 101pf, 102pf, 103pf na 104pf.Ukurikije theorem ya Miller, ubushobozi bwiza bwahinduwe buva mubitekerezo byinjira mubisubizo ni: C = 1 + kcf1.Aho k ni inyungu zifungura A1, kandi agaciro gasanzwe ni 120dB.CF1 ni 100pF (ntarengwa) na C ni 108pf.Dufashe ko kwinjiza urusaku ruke rwuburebure bwa sensor ni 1000m, CC ni 95000pf;Dufashe ko sensor CA ari 5000pf, ubushobozi bwa caccic yose hamwe ni 105pf.Ugereranije na C, ubushobozi bwuzuye ni 105pf / 108pf = 1/1000. Muyandi magambo, sensor ifite ubushobozi bwa 5000pf hamwe na 1000m isohora insinga ihwanye nubushobozi bwo gutanga ibitekerezo bizagira ingaruka gusa kuri CF1 0.1%.Ibisohoka voltage yumurongo wo guhinduranya ibyiciro nibisohoka bya sensor Q / ibitekerezo bya capacitor CF1, kubwibyo rero ibisobanuro bya voltage bisohoka byatewe na 0.1% gusa.
Ibisohoka bya voltage yo guhinduranya icyiciro ni Q / CF1, iyo rero ubushobozi bwo gutanga ibitekerezo ari 101pf, 102pf, 103pf na 104pf, ibisohoka ni 10mV / PC, 1mV / PC, 0.1mv / pc na 0.01mv / pc.

2) .Urwego rwo kumenyera
Igizwe na amplifier ikora A2 hamwe na sensor sensibilité ihindura potentiometero W. Igikorwa cyiki cyiciro nuko iyo ukoresheje sensororo ya piezoelectric hamwe na sensitivité zitandukanye, igikoresho cyose gifite ingufu zisanzwe zisanzwe.

3) .hanyura akayunguruzo
Icyiciro cya kabiri Butterworth ikora imbaraga zungurura hamwe na A3 nkibyingenzi bifite ibyiza byibigize bike, guhinduranya byoroshye hamwe na passband, birashobora gukuraho neza ingaruka zumurongo wihuta wibimenyetso byingirakamaro.

4) .Icyerekezo kinini
Itondekanya-ryambere-passiyo yo hejuru ya filteri igizwe na c4r4 irashobora guhagarika neza ingaruka zumwanya muto wo kwivanga kubimenyetso byingirakamaro.

5) powerIngufu zanyuma
Hamwe na A4 nkibyingenzi byunguka II, ibisohoka bigufi birinda umutekano, byuzuye.

6).Urwego rwo hejuru
Hamwe na A5 nkibyingenzi, mugihe ibisohoka voltage irenze 10vp, LED itukura kumwanya wimbere izaka.Muri iki gihe, ibimenyetso bizagabanywa kandi bigorekwe, bityo inyungu zigomba kugabanuka cyangwa amakosa akaboneka.

uburyo bwo gukoresha

1. kwinjiza impedance yo kwishyuza amplifier ni hejuru cyane.Kugirango wirinde umubiri wumuntu cyangwa voltage yindurwe yo hanze kumeneka ibyinjira byinjira, amashanyarazi agomba kuzimya mugihe uhuza sensor niyinjiza yinjiza cyangwa ikuraho sensor cyangwa ukeka ko umuhuza irekuye.
2. nubwo insinga ndende ishobora gufatwa, kwagura umugozi bizana urusaku: urusaku rudasanzwe, imashini ikora hamwe nijwi rya AC rya kabili.Kubwibyo, mugihe upimye kurubuga, umugozi ugomba kuba urusaku ruto kandi ukagabanya ibishoboka byose, kandi bigomba gukosorwa kandi kure yibikoresho binini byamashanyarazi.
3. gusudira no guteranya abahuza bikoreshwa kuri sensor, insinga hamwe na amplifier zishyuza ni abahanga cyane.Bibaye ngombwa, abatekinisiye badasanzwe bakora gusudira no guteranya;Rosin anhydrous ethanol yumuti (amavuta yo gusudira birabujijwe) azakoreshwa mu gusudira.Nyuma yo gusudira, umupira wipamba wubuvuzi ugomba gushyirwaho inzoga zidafite imbaraga (inzoga zubuvuzi zirabujijwe) guhanagura flux na grafite, hanyuma bikuma.Umuhuza agomba guhorana isuku kandi yumye kenshi, kandi ingofero yikingira igomba gukoreshwa mugihe idakoreshejwe
4. kugirango hamenyekane neza niba igikoresho gikwiye, preheating igomba gukorwa muminota 15 mbere yo gupimwa.Niba ubuhehere burenze 80% igihe cyo gushyuha kigomba kurenza iminota 30。
5. Igisubizo kidasanzwe cyibisohoka: byerekanwe cyane cyane mubushobozi bwo gutwara imitwaro ya capacitive, igereranijwe na formula ikurikira: C = I / 2 л Muri formula ya vfmax, C nubushobozi bwumutwaro (f);Ndasohoka ibyiciro bisohora ubushobozi (0.05A);V impanuka isohoka ya voltage (10vp);Umubare ntarengwa wakazi wa Fmax ni 100kHz.Ubushobozi ntarengwa rero bwo gutwara ni 800 PF.
6) .Guhindura knob
(1) Sensor sensibilité
(2) Inyungu:
(3) Kunguka II (inyungu)
(4) - 3dB ntarengwa ntarengwa
(5) Umuvuduko mwinshi wo hejuru
(6) Kurenza urugero
Iyo ibisohoka bya voltage birenze 10vp, urumuri rurenze rumurika kugirango usabe umukoresha ko imiterere yagoretse.Inyungu igomba kugabanuka cyangwa.amakosa agomba kuvaho

Guhitamo no gushiraho sensor

Nkuko gutoranya no kwishyiriraho sensor bigira ingaruka zikomeye kubipimo byukuri byo kwishyuza amplifier, ibikurikira nintangiriro ngufi: 1. Guhitamo sensor:
.Kubice bimwe byageragejwe, nubwo misa ari nini muri rusange, ubwinshi bwa sensor irashobora kugereranwa nuburinganire bwimiterere yimiterere mubice bimwe na bimwe byubaka sensor, nkibintu bimwe na bimwe byubatswe n'inkuta, bizagira ingaruka kubaturage Imiterere yimiterere yimiterere.Muri iki kibazo, ingano nuburemere bwa sensor birasabwa kuba bito bishoboka.
. inshuro.
.
2), Kwishyiriraho sensor
.Umurongo wikizenga cya screw ugomba guhuza nicyerekezo cyikizamini.Niba hejuru yubuso butoroshye cyangwa inshuro zapimwe zirenze 4kHz, amavuta ya silicone asukuye arashobora gushirwa kumurongo woguhuza kugirango urusheho guhuza.Iyo upimye ingaruka, kuberako impiswi yingaruka ifite imbaraga zinzibacyuho, ihuriro hagati ya sensor nuburyo bigomba kuba byizewe cyane.Nibyiza gukoresha ibyuma bya bolts, kandi torque yo kwishyiriraho ni 20kg.Cm.Uburebure bwa bolt bugomba kuba bukwiye: niba ari bugufi cyane, imbaraga ntizihagije, kandi niba ari ndende cyane, ikinyuranyo hagati ya sensor nuburyo gishobora gusigara, gukomera bizagabanuka, hamwe na resonance inshuro bizagabanuka.Bolt ntigomba kwinjizwa muri sensor cyane, bitabaye ibyo indege shingiro izunama kandi ibyiyumvo bizagira ingaruka.
(2) Igikoresho cyo kubika cyangwa guhinduranya bigomba gukoreshwa hagati ya sensor nigice cyapimwe.Inshuro ya resonance ya gasketi hamwe na blokisiyo yo guhinduranya irarenze cyane ihindagurika ryinshuro yimiterere, naho ubundi rezanse nshya izongerwaho muburyo.

Ibikoresho nibikoresho hamwe nimpapuro ziherekeza

1).Umurongo umwe w'amashanyarazi
2).Imfashanyigisho imwe
3).Kopi 1 yamakuru yo kugenzura
4).Kopi imwe y'urutonde
7, Inkunga ya tekiniki
Nyamuneka twandikire niba hari ikitagenda neza mugihe cyo kwishyiriraho, gukora cyangwa garanti idashobora kubungabungwa na injeniyeri w'amashanyarazi.

Icyitonderwa: Igice gishaje nimero CET-7701B izahagarikwa gukoreshwa kugeza mu mpera za 2021 (Ukuboza 31th.2021), guhera Mutarama 1 2022, tuzahindura mubice bishya numebr CET-DQ601B.
