kwishyuza amplifier numuyoboro wishyuza amplifier ibisohoka voltage ihwanye ninjiza yinjira. Ifite ibyuma bya piezoelectric, irashobora gupima umuvuduko, umuvuduko, imbaraga nibindi bikoresho bya mashini. Ikoreshwa cyane mu kubungabunga amazi, ingufu, ubucukuzi bw'amabuye y'agaciro, ubwikorezi, ubwubatsi, umutingito, ikirere, intwaro n'izindi nzego. Iki gikoresho gifite ibiranga bikurikira.
1) .Imyubakire irumvikana, umuzenguruko urakorwa neza, ibice nyamukuru nibihuza bitumizwa mu mahanga, hamwe nibisobanuro bihanitse, urusaku ruto hamwe na drift ntoya, kugirango hamenyekane neza ibicuruzwa byizewe kandi byizewe.
2). Mugukuraho attenuation yinjiza ya capacitance ihwanye na kabili yinjiza, umugozi urashobora kwagurwa bitagize ingaruka kubipimo bifatika.
3) .sohora 10VP 50mA.
4) .Gushyigikira umuyoboro wa 4,6,8,12 (utabishaka), DB15 ihuza ibisohoka, voltage ikora: DC12V.
Ihame ry'akazi
Amashanyarazi ya CET-DQ601B agizwe nicyiciro cyo guhindura ibyiciro, icyiciro cyo guhuza n'imihindagurikire y'ikirere, akayunguruzo gato, akayunguruzo keza, akayunguruzo ka nyuma kongerewe imbaraga hamwe n'amashanyarazi. Th ：
1） .Kwishyuza icyiciro cyo guhindura: hamwe na amplifier ikora A1 nkibanze.
Amashanyarazi ya CET-DQ601B arashobora guhuzwa na sensor yihuta ya piezoelectric, sensor ya piezoelectric sensor na sensor ya piezoelectric. Ikintu rusange kibaranga ni uko ingano yubukanishi ihindurwamo intege nke Q iringaniza nayo, kandi ibisohoka impedance RA ni ndende cyane. Icyiciro cyo guhindura amafaranga ni uguhindura amafaranga muri voltage (1pc / 1mV) ihwanye no kwishyurwa no guhindura impanvu nyinshi zisohoka muburyo buke bwo gusohoka.
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 kabili ubushobozi.
Ci - Iyinjiza ubushobozi bwa amplifier ikora A1, agaciro gasanzwe 3pf.
Icyiciro cyo guhindura amafaranga A1 yakira Abanyamerika mugari-Precision Operational Amplifier hamwe nimbaraga nyinshi zinjiza, urusaku ruke na drift. Ubushobozi bwo gutanga ibitekerezo CF1 ifite inzego enye za 101pf, 102pf, 103pf na 104pf. Ukurikije theorem ya Miller, ubushobozi bwiza bwahinduwe buva mubitekerezo byinjira mubitekerezo ni: C = 1 + kcf1. Aho k ninyungu zifunguye za A1, kandi agaciro gasanzwe ni 120dB. CF1 ni 100pF (ntarengwa) na C ni 108pf. Dufashe ko ibyinjijwe byurusaku ruke rwuburebure bwa sensor ari 1000m, CC ni 95000pf; Dufashe ko sensor CA ari 5000pf, ubushobozi bwa caccic yose hamwe ni 105pf. Ugereranije na C, ubushobozi bwose ni 105pf / 108pf = 1/1000. Mu yandi magambo, sensor ifite ubushobozi bwa 5000pf hamwe na 1000m isohora insinga ihwanye nubushobozi bwo gutanga ibitekerezo bizagira ingaruka gusa kuri CF1 0.1%. Ibisohoka biva mumashanyarazi yo guhinduranya icyiciro nigisohoka cyama sensor ya Q / ibitekerezo bya capacitor CF1, kubwibyo rero ukuri kwamashanyarazi asohoka bigira ingaruka kuri 0.1% gusa.
Ibisohoka byumuvuduko wicyiciro cyo guhindura icyiciro ni Q / CF1, ubwo rero iyo ubushobozi bwo gutanga ibitekerezo ari 101pf, 102pf, 103pf na 104pf, ingufu zisohoka ni 10mV / PC, 1mV / PC, 0.1mv / pc na 0.01mv / pc.
2) .Urwego rwo kumenyekanisha
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 zisohoka.
3) .kurikira akayunguruzo
Icyiciro cya kabiri Butterworth ikora imbaraga zungurura hamwe na A3 nkibyingenzi bifite ibyiza byibigize bike, guhinduranya byoroshye hamwe na passband ya passband, bishobora gukuraho neza ingaruka zibimenyetso byihuta byihuta kubimenyetso byingirakamaro.
4) ．Icyerekezo kinini cyo kuyungurura
Itondekanya rya mbere 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 induction yo hanze kumeneka ibyinjira byinjira, amashanyarazi agomba kuzimya mugihe uhuza sensor ninjiza yongerewe amafaranga cyangwa gukuramo sensor cyangwa gukeka ko umuhuza arekuye.
2. nubwo insinga ndende ishobora gufatwa, kwagura umugozi bizana urusaku: urusaku rudasanzwe, umuvuduko wa mashini 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. Iyo bibaye ngombwa, abatekinisiye badasanzwe bazakora gusudira no guteranya; Rosin anhydrous ethanol yumuti (amavuta yo gusudira birabujijwe) azakoreshwa mugusudira. Nyuma yo gusudira, umupira wipamba wubuvuzi ugomba gushyirwaho inzoga zidafite amazi (inzoga zubuvuzi zirabujijwe) guhanagura flux na grafite, hanyuma bikuma. Umuhuza agomba guhorana isuku kandi yumutse kenshi, kandi ingofero yingabo igomba gukururwa mugihe idakoreshejwe
4. kugirango hamenyekane neza niba igikoresho gikwiye, ubushyuhe bukorwa mu minota 15 mbere yo gupimwa. Niba ubuhehere burenze 80% igihe cyo gushyuha kigomba kuba kirenze iminota 30。
5. Igisubizo kidasanzwe cyibisohoka: byerekanwe cyane mubushobozi bwo gutwara imizigo ya capacitif, igereranywa na formula ikurikira: C = I / 2 л Muri formula ya vfmax, C nubushobozi bwumutwaro (f); Nsohora ibyiciro bisohoka ubushobozi (0.05A); V impanuka isohoka ya voltage (10vp); Umubare ntarengwa wakazi wa Fmax ni 100kHz. Ubushobozi ntarengwa bwo gutwara ibintu ni 800 PF.
6) .Guhindura knob
(1) Sensor sensibilité
(2) Inyungu:
(3) Kunguka II (inyungu)
(4) - 3dB ntarengwa ntarengwa
(5) Umuvuduko mwinshi ntarengwa
(6) Kurenza urugero
Iyo ibisohoka voltage irenze 10vp, urumuri rurenze rumurika kugirango usabe umukoresha ko imiterere ya flake yagoretse. Inyungu igomba kugabanuka cyangwa. amakosa agomba kuvaho
Guhitamo no gushiraho sensor
Nkuko guhitamo no kwishyiriraho sensor bigira ingaruka zikomeye kubipimo byukuri byo gupima ibyongerewe amafaranga, ibikurikira nintangiriro ngufi: 1. Guhitamo sensor:
. Kubice bimwe byageragejwe, nubwo misa ari nini muri rusange, ubwinshi bwa sensor irashobora kugereranwa nuburinganire bwaho bwimiterere mubice bimwe na bimwe byashizweho na sensor, nkibintu bimwe na bimwe byubatswe n'inkuta, bizagira ingaruka kubaturage icyerekezo cyimiterere yimiterere. Muri iki kibazo, ingano nuburemere bwa sensor birasabwa kuba bito bishoboka.
. inshuro.
.
2), Gushiraho sensor
. Umurongo wimyenda ya screw igomba kuba ijyanye nicyerekezo cyikizamini. Niba hejuru yubuso butoroshye cyangwa inshuro zapimwe zirenze 4kHz, amavuta ya silicone asukuye arashobora gushirwa kumurongo woguhuza kugirango utezimbere umurongo mwinshi. 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 izaba yunamye kandi ibyiyumvo bizagira ingaruka.
(2) Igikoresho cyo kubika cyangwa guhagarika bigomba gukoreshwa hagati ya sensor nigice cyapimwe. Inshuro ya resonance ya gasketi no guhinduranya irenze cyane kurenza ihindagurika ryinshuro yimiterere, naho ubundi rezanse nshyashya izongerwa muburyo.
