Feem ntau cov nplhaib sib txhuam siv kev sib txhuam ua daim ntawv txuas hluav taws xob. Nws muaj kev nyab xeeb, txhim khu kev qha, thiab tuaj yeem ua tau raws li tus lej ntawm cov channel uas cov neeg siv khoom xav tau. Cov nplhaib sib txhuam tam sim no hauv khw feem ntau siv daim ntawv sib cuag no. Lwm yam suav nrog kev sib cuag mercury, kev xa xov infrared, kev xa xov wireless, thiab lwm yam, uas tsis yog cov khoom tseem ceeb tam sim no, vim tias cov nplhaib sib txhuam disc tsim tawm hauv txoj kev no tseem muaj ntau qhov kev txwv, xws li qhov teeb meem ntawm kev xau mercury, thiab nws nyuaj rau tsim ntau dua 8 channel, thiab tus nqi tsim khoom siab heev. Kev xa xov infrared thiab kev xa xov wireless muaj teeb meem cuam tshuam teeb liab, thiab cov channel fais fab siab tsis tuaj yeem xa mus rau txoj kev no.
Cov sib dhos ntawm lub nplhaib sib tsoo tuaj yeem muab faib ua cov nplhaib sib tsoo zaus tsawg, cov nplhaib sib tsoo zaus nruab nrab, thiab cov pob qij tig zaus siab raws li zaus ntawm lub teeb liab kis. Cov nplhaib sib tsoo feem ntau tsuas yog hais txog ob hom thawj zaug xwb. Cov ntsuas hluav taws xob ntawm cov sib dhos ntawm lub nplhaib sib tsoo yog: kev tiv thaiv rwb thaiv tsev, kev tiv thaiv kev sib cuag, lub zog dielectric thiab crosstalk. Rau cov nplhaib sib tsoo zaus nruab nrab, vim tias zaus siab, kev tiv thaiv, kev sib phim impedance, lub suab nrov, thiab lwm yam kuj yuav tsum tau xav txog. Hauv kev tsim qauv, kev sib cuag txhim khu kev qha yuav tsum tau ua ntej kom ntseeg tau tias txhua kab txuas tas mus li. Yog li ntawd, qhov hluav taws xob conductivity ntawm cov khoom siv rau txhuam yuav tsum zoo, qhov siab ntawm lub nplhaib sib tsoo yuav tsum tsim nyog, qhov eccentricity thiab kev co ntawm lub nplhaib sib tsoo yuav tsum me me, qhov kev tiv thaiv hnav yuav tsum zoo, qhov sib txhuam torque yuav tsum me me, thiab nws yuav tsum yooj yim rau kev tswj hwm.
1) Lub nplhaib sib tsoo zaus qis: lub nplhaib sib tsoo uas siv kev sib txhuam los xa cov cim zaus qis thiab lub zog. Cov nplhaib sib tsoo feem ntau yog cov nplhaib sib tsoo cylindrical thiab cov nplhaib sib tsoo sib txawv. Cov nplhaib conductive ntawm cov nplhaib sib tsoo cylindrical tau muab faib ua cov nplhaib tiaj tus thiab cov nplhaib V-puab. Cov ntaub ntawv ntawm cov nplhaib conductive feem ntau yog tooj liab, tooj dag, npib nyiaj thiab kub. Cov txhuam yog palladium, kub alloy lossis kub-plated hlau txhuam thiab tooj liab-graphite composite txhuam. Yog tias tus lej ntawm cov nplhaib sib tsoo loj, lub nplhaib sib tsoo cylindrical muaj ob pawg ntawm cov txhuam sab saud thiab qis thiab lub adapter sib txawv, tab sis nws qhov loj me axial yog loj. Kev siv cov nplhaib sib tsoo sib txawv tuaj yeem txo qhov loj me axial, ntim thiab hnyav. Lub nplhaib sib tsoo sib txawv muaj ob pawg ntawm cov txhuam sab saud thiab qis thiab lub adapter sib txawv. Cov txhuam sab saud tig nrog azimuth ntawm lub kav hlau txais xov, thaum cov txhuam sab qis yog kho. Muaj ob pawg ntawm cov khoom sib cuag sab saud thiab qis ntawm lub phaj adapter sib txawv. Cov khoom sib cuag sib xws tau txuas nrog cov xov hlau, thiab lub tshuab sib txawv yog siv los ua kom nws qhov kev sib hloov ceev 1/2 ntawm qhov kev sib hloov ceev azimuth. Thaum lub kav hlau txais xov tig, cov hluav taws xob ntws mus rau hauv txhua txhuam qis dua hla dhau ib lossis ob lub voj voog sib cuag ntawm lub rooj sib txawv thiab ntws tawm ntawm txhuam sab saud kom ntseeg tau tias lub voj voog ntawm qhov chaw ruaj khov thiab qhov chaw tig ib txwm txuas nrog. Cov hmoov hnav los ntawm lub nplhaib sib txhuam swb tuaj yeem ua rau muaj luv luv ntawm cov nplhaib. Yog li ntawd, cov qauv yuav tsum xyuas kom meej tias nws yooj yim los ntxuav, thiab cov qauv sib xyaw ua ke feem ntau yog siv los pab kho lossis hloov cov khoom hauv qhov chaw.
2) Lub nplhaib sib nqus zaus nruab nrab: lub nplhaib sib dhos siv los xa cov teeb liab thiab lub zog ntawm radar zaus nruab nrab (kaum tawm megahertz). Lub nplhaib sib nqus no muaj zaus siab dua thiab yuav tsum tau tiv thaiv. Cov nplhaib sib nqus ceev ceev kuj tseem siv tau los xa cov teeb liab qis dua 12MHz. Ib lub nplhaib txuas nrog tus neeg xyuas pib nruab nrab, thiab lwm lub nplhaib txuas nrog txheej sab nraud ntawm lub cable ua lub nplhaib tiv thaiv. Cov nplhaib sib nqus coaxial feem ntau siv los xa cov teeb liab saum 12MHz. Qhov seem ntawm lub nplhaib sib nqus no yog qhov zoo li qhov zawj, uas yog qhov tseem ceeb ntawm tus neeg xyuas pib coaxial rectangular. Kuj tseem muaj lub nplhaib sib nqus zaus nruab nrab capacitive, tus neeg xyuas pib nruab nrab yog annular, txhawb nqa los ntawm lub ncoo rwb thaiv tsev hauv txheej tiv thaiv, muaj qhov sib txawv ntawm qhov tig thiab qhov ruaj khov, thiab lawv tsis kov ib leeg, thiab cov teeb liab zaus nruab nrab yog txuas los ntawm capacitance. Yog tias muaj qhov txwv ntawm qhov tig ntawm lub antenna, lub cuab yeej winding cable tuaj yeem siv hloov lub nplhaib sib nqus.
