Nkag siab hom kev siab hauv Automation: Ntsuas, Tsis Txaus, thiab Qhov Sib Txawv - Xaiv Txoj Cai Sensor Hnub no

Hauv cov txheej txheem automation, qhov ntsuas qhov tseeb yog qhov tseem ceeb rau kev nyab xeeb, kev ua haujlwm, thiab kev ua haujlwm. Tab sis tsis yog txhua qhov kev nyeem ntawv siab yog tib yam. Txhawm rau txhim kho koj qhov teeb tsa, koj yuav tsum nkag siab qhov sib txawv ntawm qhov ntsuas qhov siab, qhov siab kawg, thiab qhov sib txawv siab - txhua qhov muaj cov ntsiab lus siv tshwj xeeb thiab siv cov ntaub ntawv. Cov lus qhia no ua kom yooj yim rau qhov sib txawv thiab pab koj xaiv qhov zoo sensor rau koj daim ntawv thov.

Gauge Pressure yog dab tsi?

Gauge siab (P_ntsuas) ntsuas qhov siab txheeb ze rau lub zos atmospheric siab. Feem ntau cov kev lag luam thiab cov cuab yeej siv niaj hnub - zoo li lub log tsheb ntsuas thiab cov tshuab hydraulic - pom qhov ntsuas siab.

Formula:

Siv Case:

Pneumatics, log tsheb inflation, dej twj

Lus Cim: Kev ntsuas siab tuaj yeem yog qhov tsis zoo (nqus) lossis zoo.

✔ Zoo tagnrho rau: Kev saib xyuas kev lag luam dav dav nyob qhov twg ambient siab ruaj khov.

Dab tsi yog Qhov Siab Tshaj Tawm?

Siab siab (P_abs) yog ntsuas tawm tsam lub tshuab nqus tsev zoo meej. Nws suav rau ob qho tib si atmospheric siab thiab ntsuas qhov siab, muab qhov tseeb, ruaj khov siv-tshwj xeeb yog qhov tseem ceeb hauv kev tshawb fawb lossis cov ntsiab lus siab.

Formula:

Siv Case:

Aerospace, thermodynamics (piv txwv li, gas laws), lub tshuab nqus tsev

✔ Zoo tagnrho rau: Cov ntawv thov uas xav tau qhov tseeb siab thoob plaws qhov siab sib txawv.

Dab tsi yog Differential Pressure?

Differential siab (ΔP) yog qhov sib txawv ntawm ob lub ntsiab lus siab hauv ib qho system. Nws tsis yog khi rau atmospheric siab thiab yog qhov tseem ceeb rau kev kuaj xyuas qhov ntws, tsis kam, lossis qib sib txawv.

Formula:

Siv Case:

Flow meters, lim, tank qib saib xyuas

✔ Zoo tagnrho rau: Cov txheej txheem tswj, ntsuas tus nqi ntws, HVAC ntsuas.

Xaiv txoj cai Pressure Sensor

Txawm hais tias koj tab tom ntsuas lub tshuab nqus tsev, tswj cov huab cua kom zoo, lossis saib xyuas lub kaw lus hydraulic, xaiv hom kev siab zoo yog qhov tseem ceeb:

• Siv cov sensors siab rau qhov tseeb hauv qhov chaw hloov pauv.
• Siv cov ntsuas ntsuas ntsuas rau kev ua haujlwm txhua hnub.
• Siv cov transmitters sib txawv los ntsuas qhov sib txawv ntawm cov khoom sib txawv.

Kev xav zaum kawg: Ua kom zoo rau koj qhov system nrog txoj cai kev pom zoo

Kev nkag siab txog hom kev ntsuas siab ua kom cov ntaub ntawv raug, kev ua haujlwm nyab xeeb dua, thiab tswj tau zoo dua. Tsis txhob cia qhov tsis sib haum xeeb ntawm sensor thiab siab hom cuam tshuam koj lub cev.
