Pinpointer izandla siqu: idayagramu kanye nencazelo

Pinpointerami kulezizinsuku ubizwa ngokuthi compact metal detector. Ngokusho ekilasini ukunemba bona awafani. Kufanele kukhunjulwe ukuthi lolu hlobo idivayisi has ukuzwela lalo. The main isici pinpointera kungenziwa ngokuthi ikhoyili. Ubeka ke uhlobo ikakhulukazi orthogonal. Nokho, kulesi simo, okuningi kuncike ekilasini lokunemba yomculo. Ukuze ukuqoqa elula pinpointer ngezandla zabo, kufanele kube ujwayelene ukucupha owaziwa.

Model phezu capacitor ezimbili wire

Ukuze wenze lokhu uhlobo pinpointer izandla zami siqu, kubalulekile kuqala kuzo zonke ukulungiselela izindlu kudivayisi. Ukuze wenze lokhu, ochwepheshe abaningi batusa ukusebenzisa flashlight evamile. Inkinga eyinhloko kulesigaba ukuthola modulator ezinhle. Njengomthetho, ezimbili-wire capacitor thatha analog non-eqondile. Ngqo ikhoyili lesibopho ngokufanele phambi idivayisi. Amabhethri kufanele afakwe for the modulator. Susa nabo angaba futhi flashlight. amandla webhethri Ubuncane iyadingeka ukuba 200 mah. Ngemuva kwemizuzu engu-komsebenzi okuqhubekayo 25 lokhu kahle ngokwanele.

Ukusebenzisa capacitors emithathu wire

Yenza nzima ne ezintathu-wire capacitors pinpointer izandla zami siqu. I modulator kulokhu ofanele kuphela komugqa hlobo. Esikhathini sethu ukuze uyithole ku electronics ezitolo akulula. Kufanele kukhunjulwe ukuthi ikhoyili kumele afakwe ngezansi amplifier. Ezinye okwengeziwe ifakwe idivayisi zener. Ukuze kwandiswe nozwela imodeli, bona uvumelane ngokuphelele. Amabhethri kulesi simo, ungasebenzisa i-flashlight ejwayelekile.

isignali kokuphazamiseka Model

Ukuqoqa lolu hlobo pinpointer izandla zami siqu, kubalulekile kuqala kuzo zonke ukuthatha umzimba i-flashlight. Ubuncane embundwini imvamisa modulator kumelwe ukumelana 200 Hz. Konke lokhu kuzosiza silondoloze ukuzwela zedivayisi ezingeni eliphezulu. Njengoba umhloli Le divayisi isetshenziselwa kaningi. Ukuze kusebenze imodi uphazamisa ekwakhiweni kwadingeka kuvulwe control.

Ngokuvamile isetshenziswa inkinobho-hlobo. Kulokhu, kufanele sinake izici zomzimba, neyayingaphansi flashlight. Ikhoyili le njongo kungcono ukukhetha elula. Nokho, okokufaka voltage umkhawulo kudingeke ukuba zigcinwe ngaso 15 V. Konke lokhu kuzothuthukisa ukunemba ukufunda.

Ukuguqulwa "Kid-FM2"

Ukuqoqa pinpointer "Kid-FM2" ngezandla zakhe ulula. Wathi kudivayisi ungachazwa ukuthi ongaphakeme e ukuzwela. Nokho, izindleko imodeli liphansi kakhulu, futhi idivayisi wathi ilungele ukusetshenziswa ekhaya. I modulator kuleli cala uhlobo non-eqondile. Yena ukukhwezwa ngqo eduze Regulator.

analogs Ivame ukutholakala turning zingatholakala emakethe. Inductor okokufaka embundwini voltage uyakwazi withstanding kufike 10 V. Kufanele kuphawulwe ukuthi idivayisi conductivity eliphakeme zamanje. Lokhu kwenziwa ngokufaka diode zener. Ngaphezu kwalokho, ukuba baphakamise izandla pinpointer "Kid-FM", kubalulekile ukuba solder capacitors. Kungaleso sikhathi kuphela lapho ukuxhuma oxhumana nabo diode zener. Ekupheleni umsebenzi ngeke kuphela silungise amabhethri kuleli cala.

Pinpointer ukuzwela ongaphakeme transistors

Yenza ongaphakeme ukuzwela pinpointer ngezandla zakhe phezu transistors kungaba ngenxa idivayisi ezifana beeper. It efakwe emzimbeni nje ngemuva modulator. Zesikhulisa kule divayisi kufanelekile kuphela ishayela hlobo. Ngakho kungenzeka capacitors akhethiwe amadivayisi ahlukahlukene. Nokho, ubuncane okokufaka embundwini voltage, balindeleke ukuba bakwazi ukugcina at 5 V

Kufanele kuphawulwe ukuthi idivayisi zener ngokuvamile ifakiwe. Reserve imvamisa bamukelekile 200 Hz. Kubalulekile ukukhumbula ukuthi ukunemba kufundwa incike inductance kwekhoyili. Ububanzi isici ukudluliswa ngokuvamile kakhulu esingaphansi 3 microns. Amabhethri onobuhle ekhethiwe ephethe umthamo ezingekho ngaphezulu kuka-600 mah. Enough lokhu, idivayisi ngokuqhubekayo imizuzu engaphezu kwengu-30.

High Ukuzwela Model

ukuzwela High pinpointer indlela yokwenza ngezandla zakho siqu? Ukuze uqonde lo mbuzo, kufanele kuqondwe ukuthi ikhoyili bazodinga enamandla sasivumela ukuba ahlanganiswe. Ubuncane embundwini voltage kumelwe ukumelana at 20 V. Kufanele kuqashelwe ukuthi le modulators kulokhu afaneleka kuphela umugqa hlobo. Ukunemba futhi kuncike hlobo condensates.

Kulesi simo, ochwepheshe abaningi luleka esebenzisa onobuhle evulekile. Ngokwesilinganiso, ukubeka besikhundla element idatha emhlabeni 5 PF. Nokho, kulesi simo, okuningi kuncike nomkhiqizi capacitors. Uma sikhuluma diode zener, isetshenziswa kahle emzimbeni anda. Kuyadingeka ukwandisa ukuzwela zedivayisi. Amabhethri ngalolu hlobo kufanele kukhethwe nge namandla hhayi ngaphansi kuka 900 mah.

Ukuguqulwa Minimax-PP

Ukuqoqa izandla zabo pinpointer Minimax-PP, kufanele sithathe uchungechunge beeper PP20. Kufanele kuqashelwe ukuthi le izindlela vibration ukufakwa amadivaysi yalolu hlobo. Kulokhu, izinkomba esetshenziswa ezihlukahlukene. Uma sikhuluma ikhoyili, isetshenziswa kulesi simo uhlobo orthogonal. Okufakwa embundwini voltage ukuthi ingxenye bayakuma phambi okungenani 15 W. ukumelana yesifunda akufanele idlule 4 ohms.

Ukuzwela zedivayisi ixhomeke capacitor. Linani selilonkhe lebantfu labange ezimbili kule scheme ejwayelekile enikeziwe. Omunye wabo ngempela efakwe eduze lekhoyili. Lapha, wesibili ukukhwezwa ngaleso ophumayo modulator. Inkinga eyinhloko lezi amadivaysi kungaba ibhekwe transmittance encane ububanzi at 2 microns. Ngenxa yalokho, lo yokukhulisa umsindo esetshenziswa amadivaysi yalolu hlobo awavamile.

Idivayisi isilawuli ebalulekile

Ingabe lolu hlobo pinpointer izandla siqu (scheme kukhonjisiwe ngezansi) ulula. Okokuqala kubalulekile yedivayisi eyolanda icala omuhle. Kulokhu, isilawuli uhlobo ebalulekile eningi isikhala akusho luthathe. Uma wayefisa angathengwa ngasiphi esitolo nge ubuchwepheshe umsakazo, futhi kubiza kancane kakhulu. I lolwehlukanisa lesi sici kungaba ibhekwe conductivity ezinhle. I capacitors kulokhu esungulwe ezimbili electrode hlobo. Ukumelana ipharamitha e isilinganiso sabo endiza eduze 2 ohms.

Kufanele kuphawulwe ukuthi ikhoyili kumele afakwe kuqala. It kuyodingeka usebenzise Blowtorch. Ngaphezu kwalokho enamathiselwe ngokuqondile modulator. Ngo ezingemuva ingxenye kufanele kube ebhethri elishajekayo. Lo mshini kulesi simo ukusetshenziswa okungalungile. Sibangelwa yokuthi nozwela idivayisi is kakhulu ziyancipha ngenxa anda imvamisa nokukhawulela wezinsimbi zomculo.

Ukusetshenziswa capacitors multilayer

It is uya multilayer capacitors pinpointer izandla zabo (scheme kukhonjisiwe ngezansi) kuphela khona ohlobo orthogonal. I modulators kulokhu Site komugqa nezinhlobo non-eqondile. Kufanele kukhunjulwe ukuthi amadivayisi yalolu hlobo ngokuvamile basuke efakwe izindlela Isixwa. Kulokhu, beepers zingatholakala kaningi.

Ukuze kwandiswe ukuzwela amadivayisi zener avame ukusetshenziswa. Kulesi ethandwa kakhulu namuhla kukhona nozakwabo kardiodnye. Ukufaka kubo kuyodingeka usebenzise i Blowtorch. Ngokuvamile, kufanele kuphawulwe ukuthi onobuhle nge multi ungqimba capacitors kukhona jikelele, futhi mahle ukusetshenziswa ekhaya. Ngosizo lwabo, umuntu uyakwazi angabacwasi ngokushesha ukuthola indawo esiqondile wiring ogangeni.

Model ebhodini Monolithic

Ukuqoqa lolu hlobo pinpointer izandla siqu ulula. Umehluko phakathi amadivayisi okusezingeni eliphezulu ukunemba ukufundwa, kodwa futhi ukuzwela okuhle, hhayi nje. Ukuze ochwepheshe wathi imodeli kungahlali kahle. Ukuqoqa idivayisi ne ezidingekayo ukulungisa modulator. Kulokhu, ochwepheshe abaningi batusa ukusetshenziswa komugqa analogue.

Nokho, ukuhlela kabusha non-eqondile luvamile. Beeper kulokhu lesibekiwe kwekhoyili. Sepharamitha kwidivaysi yokufakwayo embundwini voltage kumele singeqi 20 V. ngenxa yale njongo zener compulsorily setha. Izilawuli kulokhu soldered oyifunayo. Ekupheleni umsebenzi ngeke kuphela silungise amabhethri.

Pinpointer nge control resonance

Ukuze Songa idivayisi Umlawuli resonance, kubalulekile ukulungiselela kusengaphambili a Blowtorch. Iyunithi yokuqala ekhethelwe izinga modulator. Ochwepheshe abaningi namanje batusa ukusetshenziswa komugqa analogue kulesi simo. Zithole esitolo kunzima, kodwa kumele babe encane. Isilinganiso conductivity ukubeka kubo elilingana 3 microns. Ngenxa yalokhu, voltage okokufaka embundwini ukuba wethembe at 15V Zener diodes zifanelekile ngokwezinhloso onhlobonhlobo. Ukumelana Maximum banayo ukuba siqhubeke ezingeni 5 ohms. Kufanele kuqashelwe ukuthi le Izilawuli kudivayisi beeper kungukuthi ezidingekayo.

Ukufaka ikhoyili kulesi simo kungcono kuhlale. Kulokhu, ukwahlukanisa wiring kumele inikezwe ukunakekelwa okukhethekile. Kufanele kukhunjulwe ukuthi ebiyelwe kufanele moya ngokuphelele. Ngenxa yale njongo, njengenhlangano kungenzeka okunye ukusebenzisa uphawu zenjoloba. Ngqo Regulator kumele soldered kuya modulator. Capacitors kulesi simo ngokuyinhloko esetshenziswa emkhakheni hlobo. umthamo Ubuncane ibhethri iyadingeka ukuba 800 mah.
