Pinpointer izandla zabo: umzobo kunye nenkcazelo

Pinpointerami mihla ibizwa metal detectors compact. Ngokutsho iklasi accuracy ukuba zahluke kakhulu. Kufuneka kwakhona kukhunjulwa ukuba olu hlobo lefowuni ubuntununtunu yayo. Isiqalelo pinpointera engundoqo nga ngokuba coil. Ubeka kuyo zohlobo orthogonal. Noko ke, kule meko, okuninzi kuxhomekeke kudidi lwe yesixhobo nokuchaneka. Ukuze aqokelele elula pinpointer ngezandla zabo, kufuneka babenolwazi sisimo ezaziwayo-kakuhle.

Model kwi wire ezimbini capacitor

Ukwenza olu hlobo pinpointer ngezandla zakhe, oko kuyimfuneko kuqala ukulungiselela izindlu ukuba icebo. Ukuze wenze oku, iingcali ezininzi yaleza ukusebenzisa layita eqhelekileyo. Le ngxaki iphambili kweli nqanaba ukuze ufumane modulator elungileyo. Njengomgaqo, ucingo-ezimbini capacitor ukhethe analog non-linear. Ngqo coil yento ilahlwa phambi kwefowuni. Iibhetri kufuneka esifakelwa modulator. Susa kwabo nazo layita. Ubuncinane amandla ebhetri kufuneka ukuba ube 200 mah. Emva kwemizuzu 25 of operation rhoqo oku kakhulu ngokwaneleyo.

Ukusebenzisa capacitors wire ezintathu-

Yenza nzima kakhulu kunye capacitors ngocingo ezintathu-pinpointer ngezandla zabo. Le modulator kulo mzekelo kuphela uhlobo lwento efanelekileyo. Ekuhambeni kwexesha lethu wayifumana ezivenkileni zombane akukho lula. Kufuneka kwakhona kukhunjulwa ukuba Ikhoyili kufuneka zifakwe ngezantsi lo mshini. Ezinye izixhobo ngakumbi isixhobo zener. Ukwandisa uvakalelo yemodeli, ayadibana ngokugqibeleleyo. Iibhetri kule meko, ungasebenzisa layita eqhelekileyo.

Kwemodeli uphawu nokuphazamiseka

Ukuqokelela olu hlobo pinpointer ngezandla zakhe, oko kuyimfuneko kuqala ukuba umzimba isibane. Ubuncinane umbundu frequency modulator kufuneka ukumelana 200 Hz. Konke oku kuya kunceda ukugcina uvakalelo kwefowuni kwinqanaba eliphezulu. Njengoko umvavanyi Esi sixhobo lisetyenziswa kaninzi. Ukuvula imo angaluphazamisa kwi zokwakha ezifunekayo ukuseka ulawulo.

Amaninzi asisetyenziswa iqhosha-hlobo. Kulo mzekelo, kufuneka ahlawule ingqalelo iimpawu zomzimba, leyo osezandleni isibane. Coil yale njongo kungcono ukukhetha elula. Nangona kunjalo, lo umda ombane ngegalelo ekufuneka zigcinwe kwi-15 V. Konke oku kuza kuphucula ukuchana ukufunda.

Zolungiso "Kid-FM2"

Qokelela pinpointer "Kid-FM2 'ngezandla zakhe ilula. Uthe isixhobo ungachazwa ukuba ephantsi uvakalelo. Nangona kunjalo, ixabiso le modeli lisezantsi kakhulu, kwaye isixhobo wathi ezilungele ukusetyenziswa ekhaya. Le modulator kulo mzekelo uhlobo non-linear. Ke wamkhwelisa elandelayo ngqo umlawuli.

analogs amaninzi ke ukujika inokufumaneka emarikeni. Inductor input umbundu ombane ekwaziyo withstanding kuma-10 V. Kufuneka kuqatshelwe ukuba icebo yangoku ephezulu conductivity. Oku kufikelelwe kokufaka diode zener. Ngaphezu koko, ukuba ukuphakamisa izandla zabo pinpointer "Kid-FM", oko kuyimfuneko capacitors solder na. Kuphela koko ukudibanisa abafowunelwa diode zener. Ekupheleni kwalo msebenzi uya ukulungisa kuphela iibhetri kweli tyala.

Pinpointer transistors Uvakalelo oluphantsi

Kulithoba ubuzaza pinpointer ngezandla zakhe phezu transistors inokuba ngenxa kwisixhobo ezifana a pill. Lifakwe emzimbeni nje emva modulator. Sesimangalo kule divaysi kuphela uhlobo ukubetha efanelekileyo. Ngoko ke capacitors zingachongelwa izixhobo ezahlukeneyo. Nangona kunjalo, le ombane ubuncinane igalelo threshold, kufuneka ukuba agcine 5 V.

Kufuneka kuqatshelwe ukuba isixhobo zener idla ifakiwe. Reserve frequency of udle 200 Hz. Kubalulekile ukuba kukhunjulwe ukuba ukuchaneka ukufunda ixhomekeke inductance le coil. Ububanzi element ugqithiso isikakhulu microns ngaphantsi kwe-3. Iibhetri njengezibonelo ezikhethiweyo kunye umthamo ongekho ngaphezu kwe-600 mah. Kwanele yale ngayo, isixhobo ngokuqhubekayo imizuzu kwama-30.

Ukuqaphela Model High

uvakalelo oluphezulu pinpointer ukwenza njani izandla zakho? Ukuze uqonde lo mbuzo, kufuneka kuqondwe ukuba coil kuya kufuneka enamandla ngokufanelekileyo ukuze ibandla. Ubuncinane ombane threshold kufuneka ukumelana kwi-20 V. Kufuneka kuqatshelwe ukuba modulators kulo mzekelo kuphela uhlobo line efanelekileyo. Ukuchana kwakhona ixhomekeke kuhlobo condensates.

Kule meko, iingcali ezininzi ukucebisa usebenzisa uvule. Kwi-avareji, ehleli umthamo kwi isiqalelo data ngeenxa 5 PF. Noko ke, kule meko, okuninzi kuxhomekeke umenzi capacitors. Ukuba sithethe diode zener, lisetyenziswa nokonyuka uxhathiso. Kuyimfuneko ukwandisa uvakalelo kwefowuni. Iibhetri kule modeli kufuneka zikhethwe kunye umthamo ongekho ngaphantsi kwe 900 mah.

Nenguqulo Minimax-PP

Ukuqokelela izandla zabo pinpointer Minimax-PP, kufuneka ukhethe up kuthotho pill PP20. Kufuneka kuqatshelwe ukuba iindlela kokukona efakiweyo ngamayelenqe yalo hlobo. Kulo mzekelo, nezalathi wasebenzisa ezahlukahlukeneyo. Ukuba sithethe Ikhoyili, lisetyenziswa kulo mzekelo hlobo orthogonal. Igalelo Ungeno enombane ngelo candelo uya ukumelana ubuncinane 15 W. The uxhathiso kwisekethe mayingagqithi ohms 4.

Uvakalelo isixhobo ubukhulu becala kuxhomekeke capacitor. Zizonke ababini kwisikimu standard enikiweyo. Omnye kubo ukuba ifakelwe kufuphi coil. Apha, owesibini elapha ophumayo modulator. Ingxaki engundoqo ezi zingaba kuthathelwa ingqalelo i transmittance encinane ububanzi kwi microns-2. Ngenxa yoko, le yokukhulisa ezisetyenziswa iingcinga olu hlobo zinqabile.

Isixhobo ne isilawuli ebalulekile

Ingaba olu hlobo pinpointer izandla zakhe (scheme eboniswe ngezantsi) ilula. Okokuqala kuyimfuneko ukuba isixhobo ukuchola ityala elungileyo. Kulo mzekelo, eli uhlobo ebaluleke kakhulu indawo ayiyi kuba nkulu. Ukuba oyifunayo, oko zingathengwa kuyo nayiphi na ivenkile kunye nobuchwepheshe radio, kwaye kubiza kakhulu. Olona phawu olwahlula lwesi sakhi nga kuthathelwa ingqalelo i conductivity elungileyo. Le capacitors kulo mzekelo esekwe hlobo electrode-mbini. ukumelana parameter kwi-avareji yawo endiza ngeenxa 2 ohms.

Kufuneka kuqatshelwe ukuba Ikhoyili kufuneka ifakwe kuqala. Kuya kufuneka usebenzise blowtorch. Ngakumbi apha ngqo modulator. Kwinxalenye bakhulise kufuneka ibe ibhetri egcwalisekayo. Lo mshini kule meko ukusetyenziswa alifanelekile. Oku kubangelwa yinto yokuba Uvakalelo ifowuni yehla kakhulu ngenxa yokonyuka rhoqo umda we sixhobo.

Ukusetyenziswa capacitors multilayer

Liya multilayer capacitors pinpointer izandla zabo (scheme eboniswe ngezantsi) kuphela xa kukho jiko orthogonal. Le modulators kulo mzekelo zilufanele kumgama owazisayo neentlobo non-linear. Kufuneka kwakhona kukhunjulwa ukuba iingcinga olu hlobo zidla efakiweyo iindlela ehlokomayo. Kulo mzekelo, beepers zingafunyanwa kaninzi.

Ukwandisa uvakalelo izixhobo zener adla ngokusetyenziswa. Kule ethandwa kakhulu kule mihla kukho kunoogxa kardiodnye. Ukuze ufake nabo kuya kufuneka ukuba basebenzise i blowtorch. Ngokubanzi, kufuneka kuqatshelwe ukuba uhle capacitors multi-umaleko akhona jikelele, kwaye ezilungele ukusetyenziswa ekhaya. Ngoncedo lwabo, umntu uyakwazi ngokukhawuleza ukufumana indawo ngqo ingcingo eludongeni.

Model kwibhodi monolithic

Qokelela olu hlobo pinpointer ngezandla zakhe ilula. Umahluko phakathi kwezi zixhobo kuphela ufundo ukuchana phezulu, kodwa ubuzaza elungileyo. Kuba iingcali uthe imodeli kahle. Qokelela isixhobo nge kuyimfuneko entengo modulator. Kulo mzekelo, iingcali ezininzi bacebisa ukusetyenziswa nucleoside yomgama.

Noko ke, ukulungisa non-linear nakho eqhelekileyo. Pill kulo mzekelo lubekelwe Ikhoyili. Ipharamitha isixhobo sokufaka threshold ombane kufuneka ingadluli 20 V. Ukulungiselela le njongo zener compulsorily usethe. Controls kulo mzekelo soldered ezinqwenelekayo. Ekupheleni kwalo msebenzi uya ukulungisa kuphela iibhetri.

Pinpointer ngolawulo ekuvakaleni kwelizwi

Ukuze ulisonge isixhobo kuMgqaliseli livakale, kuyimfuneko ukulungiselela kwangaphambili a blowtorch. Iyunithi yokuqala ezikhethelwe modulator esemgangathweni. Iingcali ezininzi bacebisa ukusetyenziswa nucleoside linear kule meko. Fumana nabo evenkileni kunzima, kodwa kufuneka babe amancinci. Le conductivity avareji zibenze ulingana microns 3. Ngenxa yoku, i-ombane ngegalelo threshold ukuba Bendinethemba 15V Zener ilight ezifanele kakhulu ezahlukileyo. Resistance eliphezulu kunyanzelekile ukuba ukugcina kwinqanaba ohms-5. Kufuneka kuqatshelwe ukuba ulawulo isixhobo pill hayi zifuneka.

Ukufakela a lale kulo mzekelo, kucetyiswa ukuba ihlale ihleli. Kulo mzekelo, i yokugquma kweentambo kufuneka anikwe ingqwalasela eyodwa. Kufuneka kukhunjulwe ukuba ebiyelweyo kufuneka zokungenisa ngokupheleleyo. Ukulungiselela le njongo, njengendlela kunokwenzeka ukuba ukusebenzisa i imitywino yerabha. Ngqo umlawuli kufuneka soldered ukuya modulator. Capacitors kule meko becala babesebenzisa uhlobo entsimini. Ubuncinane umthamo ibhetri kufuneka ukuba ube 800 mah.
