Ntaus rau xab ntev: hauj lwm

rau ntev measuring ntsuas lug siv nyob rau hauv ntau yam sectors: kev, ua liaj ua teb khwv nyiaj txiag, tus kheej kev kho, hlauv taws xob thiab lwm yam lag luam. Tag nrho cov pab kiag li lawm nyob rau hauv raws li qhov yooj yim hauv paus ntsiab lus ntawm cov embodiments raug muab faib ua txhua yam, kho qhov muag, hluav taws xob cuam tshuam, functionality uas yog raws li nyob rau hauv lub cev deb los.

elementary qauv

Qauv ntawm tus neeg kho tshuab hom - cov no yog cov sib txawv readings, ntsuas linearly. Lawv yog ua los ntawm cov hlau, fiberglass, nylon muaj ib tug vaj tsev manufactured nyob rau hauv daim kab xev los roulette kev ua tau zoo. Seev siv mus ncaj qha mus kho cov kab ntev los sequentially nyeem thav duab ntawm lub metering ntaus ntawv nyob rau hauv lub kawm tuab si lug ntawm lub xab kwv. Kawg kev tshwm sim tau tom qab tas li ntawd ntawm ib tug neeg ntsuam nyob rau hauv tus qauv units.

Tus txheej txheem nws tus kheej yog ua rau lub cev ntawm cov kwv, los yog los ntawm suspending seem pab kiag li lawm thaum uas tsis muaj qhov chaw siab tshaj, tsau nyob rau hauv fixation tripods. Tej zaum, es tsis txhob ntawm qhov tsawg kawg nkaus rau pem hauv ntej kev taw qhia ntawm checkpoints vymeryat txhais polyline. Yog xav tau qhov tseeb kab rov tav lub check ya los yog nws cais seem.

Nyob rau hauv geology thiab lwm yam hauv lub ntiaj teb kev ntsuas ntaus ntawv yog suav hais tias yog feem ntau yooj yim num daim kab xev, uas yog xam siv cov txheeb ze lengths tshwm sim (lub inaccuracy ntawm qhov kev txiav txim ntawm 1: 1500).

roulette

Xws li kev ntsuas kab lengths yog ntau txaus, raws li cov xab ntaus ntawv. Lavxias teb sab roulette nruab nrog dos nominal qhov ntev ntawm ib tug rau ib puas meters. Ib tug haumxeeb nto yog hu ua ntawv los yog sawb. Cov khoom no muaj ib tug tiv thaiv txheej thaiv tus kab xeb thiab corrosion (cov kua roj vanish, enamel, iav).

Nyob rau hauv lub pib qhov kev tso kawm ntawm lub scale ntawm xab daim kab xev, roulettes kev hloov kho muaj nyob rau hauv ob variations:

• Cov pib siv taw tes yog txav los ntawm lub kawg ntawm tsis tsawg tshaj li 1.5 cm;
• Initial suav scale yog zoo tib yam rau cov ua hauj lwm ntawm ntug lub Web site.

Kawm Tiav yog thov raws li nyob rau hauv millimeters, centimeters, decimeters thiab meters. Raws li cov neeg ntawm daim ntawv thov, muaj ob pawg: cov koob thib 3 thiab 2nd chav kawm ntawv.

Nruab nrab pab functionality roulette stainless steel yog hais txog ob txhiab seem mus thiab carbon steel - 1500 ntsuam. Ntawm xab tag nrho txiag theem yog meant ntaub, ncab ib ce tag nrho ntev ntawm lub stretch, countdown, txo lub ribbon. Rau feem ntau muaj tseeb nyeem ntawv, koj yuav tsum ua tib zoo tswj lub layout, txoj hauj lwm thiab kub, raws li tau zoo raws li ib tug qhov stretch ribbons.

roulette meej mom

Tus ntaus ntawv ntsuas ntev, hu ua Roulette, muaj ib tug xov tooj ntawm zoo. Cov muaj xws li:

• Compactness.
• Lub teeb yuag cuab tam.
• Elementarity ntaus ntawv thiab nws cov lag luam nrog siab cov neeg, nyob rau hauv particular luv luv kab.

Ntawm minuses yuav tau muab sau tseg nram qab no:

• Ib tug loj complexity nyob rau hauv cov kev ntsuas ntawm tej yam ntau.
• Yuav tsum clearance ntawm cov ua hauj lwm hauv cheeb tsam, tshwj xeeb tshaj yog thaum ntsuas cov ces kaum ntawm inclination ntawm tus neeg kab theem.

Lawv yog cov feem ntau check Polyamide daim kab xev los yog cov khoom ua los ntawm stainless hlau. Tus thawj embodiment yog ib tug pob tshab yas, uas zoo tiv thaiv lub twj paj nruag los ntawm dej thiab puas. Nrog rau cov paintings roulette tsis xeb, yog muaj nyob rau ntawm lawv cov npav yog tsis erased.

Rangefinder kho qhov muag txiav txim

Thaum ua hauj lwm rau lub yooj yim qhov chaw thiab nyob rau hauv muab tsis cuag qhov chaw feem ntau tsuas zoo ntaus ntawv ntsuas mus yog rangefinders. Cov pab kiag li lawm yog muab faib ua ib tug qauv ntawm cov kho qhov muag thiab hluav taws xob hom.

Nyob rau hauv rooj plaub thawj lub ntaus ntawv rau kev ntsuas ntawm ntev yog ib tug ntaus ntawv uas ua hauj lwm nyob rau hauv lub parallax (alternating) kab.

Ib tug nqi (X los yog Y) coj raws li ib tug qhov tus nqi, rau lwm yam - hloov. Nyob rau ntau yam, muab faib kho qhov muag rangefinders rau cov qauv nrog ib tug kuj tsis paub meej puag X thiab ib qhov kaum sab xis ntawm lub Y, los yog vice versa.

Tus tsim ntawm cov pab kiag li lawm yog nqa tawm nyob rau hauv daim ntawv ntawm cov nozzles rau lub nrig txog kev pom raj, raws li ib qho kev ywj ntaus ntawv, ib tug ua-nyob rau hauv lub caij los yog raws li ib tug ntxiv ib feem. Heev nrov rangefinder kho qhov muag txiav txim nrog paj rwb foundation thiab ruaj khov kaum sab xis.

Cov yam ntxwv ntawm tus kho qhov muag ntaus ntawv

Saib ntaus ntawv ntsuas qhov ntev ntawm ib tug tas mus li parallax lub - ib qho ntawm qhov nyuaj sab seev. Lawv yog nruab nrog rau feem ntau telescopes theodolites thiab leveling. Lub apparatus muaj ib khob phaj coated nrog ib tug khub ntawm kab rov tav threads nyob rau ntawm ib yam nrug. Lub phaj yog muab tso rau hauv lub ocular qhov chaw telescope geodesic los yog lwm yam xab ntsuas.

Siv cov apparatus nyob rau hauv lub lag luam, suav yog nqa tawm tshaj yarns huab ntsug daim phiaj slats, thiab ces tus nyob deb li yog xam los ntawm ib tug tshwj xeeb mis, nyob rau:

• L - qhia qhov txawv ntawm kev tsheb nqaj hlau;
• C - ruaj khov nqi rangefinder;
• K - coefficient, uas yog sib npaug zos rau ib puas units.

Nyob rau hauv cov neeg ntawm lub ntsuas filament rangefinder feem ntau muaj feem xyuam rau ib erroneous nyeem ntawv rau tus pas nrig, qhov yuam kev ntawm - 1/300 - 1/400.

hluav taws xob version ntawm

Ntaus ntsuas qhov ntev ntawm lub E-hom ua hauj lwm rau lub hauv paus ntsiab lus ntawm kev noj mus rau hauv tus account lub cev deb vim electromagnetic vuag muaj ib tug ruaj khov hais tawm tshaj tawm hais tias yog lub npe hu nrog high degree ntawm cov neeg.

Cov feem nrov 10 seev ntsuas ntev

Nquag siv txhua yam thiab kho qhov muag pab kiag li lawm ntsuas ntev yog cov nram qab no cov cuab yeej:

• Roulette nrog rau cov web ntawm daim kab xev thiab hlau.
• Lub laser los yog kho qhov muag ntau yam finders.
• Altimeters.
• Theem ntawm kev ntau hom.
• Theodolites.
• Tag nrho cov Noj.
• Compass.
• Electronics.
• Av raws li scanners.
• Cov koob yees duab nrog ib tug ntau yam finder.

Piv txwv li, ntsuas qhov ntev ntawm lub cable ntaus ntawv yuav tsum yog ntawm cov neeg kho tshuab hom (elemental pometrovy xam los ntawm unwinding thiab ntsuas tej qhov chaw), los yog nyob rau hauv hluav taws xob daim ntawv. Qhov tseeb qauv tso cai rau xam qhov ntev ntawm lub cable nyob rau hauv lub bay, raws li nyob rau hauv cov tsis seem ntawm cov khoom, nws hnyav thiab raug ntawm cov ntaub ntawv uas tsis muaj unwinding kauj.

nta

Ntaus ntsuas lub wavelength ntawm lub teeb qhia muaj ib tug kab, ib lub teeb qhov chaw, ib tug diaphragm, ib khub ntawm qhov kev filamentous probes latticed blocks thiab Reiter. Lub apparatus no lub measured nqi los ntawm Ntsuam xyuas cov teeb beam nyob rau hauv lub tsim tej kab nrib pleb ua hauj lwm eyepiece nrog rau tus nqi ntawm nws cov disappearance thiab tsos.

Nyob ntawm seb yuav ua li cas koj hu ua seev ntsuas ntev, koj yuav nrhiav tau tawm lawv kev khiav hauj lwm hauv paus ntsiab lus, cov nyiam tau thiab raug ntawm zaum kawg daim ntawv qhia.
