Kub Sensor: Action hauv paus ntsiab lus thiab uas

Cov hluav taws xob tswj circuits, kev tiv thaiv los yog kev tswj kheev siv kub sensor. Nws yog tsim nyog yuav tau kho cov thermal tej yam kev mob thaum lub sij hawm kev lag luam ntawm qhov sib txawv cov khoom nyob rau hauv lub chaw ua hauj lwm. Xws li yog dav siv nyob rau hauv tsev neeg cov khoom siv: tub yees, TV poob lawm, computers, thiab lwm yam Siv cov kub sensor txhob ntau xwm txheej thiab txuag lub kim cov khoom nyob rau hauv raug thiab nyob rau hauv txhua txhua hnub lub neej.

Cov pab kiag li lawm hloov lub measured kub ntawm cov kwv mus rau ib qho analog teeb liab los yog relay, to taub rau ib tug txais apparatus. Lawv txawv nyob rau hauv txoj kev ntawm lub tshav kub teeb liab hloov dua siab tshiab thiab los nyob rau hauv ob peb cov ntaub ntawv:

• Nws tau ntev tau paub hais tias thaum kub hloov txawv lub internal kuj cov ntaub ntawv. Nyob rau qhov no hauv paus, thiab raug tsim thermoresistive kub sensors. Qhov kub sensor ntawm no hom muaj ib tug me me luaj li cas thiab kev kawm zoo. Nws yog zoo ib yam nrog rau kev ua hauj lwm nyob rau hauv lub tsawg-voltage circuits nrog rau hauv circuits uas tsim muaj kev hloov nyob rau hauv kuj yog siv thiab tus tau txais lub teeb liab rau ntxiv hloov dua siab tshiab. Qhov tsis zoo ntawm cov nonlinear yam ntxwv, uas ua rau yus mob circuits kev hloov ntawm cov tau txais lub teeb liab.
• Semiconductor kub sensors khiav lag luam nyob rau hauv tib lub ntsiab cai, tab sis lawv yog cov ntau ntau rhiab thermoresistive. Lawv muaj linear yam ntxwv, lawv muaj peev xwm muab tau yooj yim manufactured nyob rau hauv tsev. Qhov tsis zoo yog cov me me rau ntawm lub ntsuas kub (-55 - +155).
• Thermoelectric converters yog lug siv nyob rau hauv manufacturing, piv txwv li, nyob rau hauv hluav taws xob arc rauv taws nte kev tswj ntawm tus txheej txheem. Tungsten los yog platinum thermocouple pawg muaj ib tug dav kub xab ntau yam. Lawv tau khiav lag luam feem ntau nyob rau hauv lub tej yam kev mob siab tshaj lub melting point ntawm ntau hlau. Qhov kub sensor ntawm no hom yuav muaj nyob rau hauv lub tsev, nws yuav siv tau los tswj qhov kub thiab txias nyob rau hauv lub sauna.
• Rau tej thaj chaw deb kub ntsuas siv tshwj xeeb pab kiag li lawm uas ntes thermal tsis emanating los ntawm rhuab lub cev. Qhov kub sensor ntawm no hom yog hu ua ib tug pyrometer. Tsis zoo ntawm tej pab kiag li lawm xws li nquag distortion kub teb thiab txo tus stability ntawm lub ntaus ntawv nws tus kheej.
• Acoustic sensors yog siv rau cov kev ntsuas nyob rau hauv cov roj thiab lwm yam kev kawm. Lawv muaj peev xwm yuav pab tau qhov chaw uas hu ntsuas txoj kev yog tsis tau. Lawv txoj ntsiab cai ntawm cov lag luam yog ua raws li cov kev hloov nyob rau hauv hais tawm tshaj tawm los ntawm zaj tsis nyob rau hauv txawv kev kawm rhuab. Kub sensors ntawm no hom muaj ib tug loj yuam kev. Feem ntau ob peb rov ntsuam yuav tsum tau cais puab cov kev ntsuas tau.

Tag nrho cov kub sensors yog lug siv nyob rau hauv lub tsim thiab kev loj hlob ntawm hluav taws xob ntawm qhov ntau thiab complexity. Yog tsis muaj lawv, nws yuav tsis yooj yim sua hauj lwm ntawm feem ntau ntawm cov schemes thiab ntawm lawv ruaj khov lag luam nyob rau ntau yam. Thaum tsim lub feem ntau xav tau ntshav rau lub hauv paus ntawm cov ntsiab yog feem ntau siv duplicate readings ntawm txawv sensors.
