Nhanganyaya: Pressure sensors zvigadziriso zvakakosha zvinoshandiswa zvakanyanya mumaindasitiri akasiyana siyana kuyera kudzvanywa kwemagasi kana zvinwiwa. Nekudaro, kuti ive nechokwadi chechokwadi uye kuvimbika kweyero mhedzisiro, kudzvanywa sensors kunoda kugaro gadzirisa. Ichi chinyorwa chinoongorora kukosha kwekudzvanywa sensor calibration, iyo calibration maitiro, uye yakajairwa calibration nzira.
Nei Calibration ichidikanwa: Nekufamba kwenguva, ma sensors anogona kusangana nekudonha kana kukanganisa nekuda kwemamiriro ekunze, kupfeka kwemuviri, kana zvimwe zvinhu. Calibration inzira yekufananidza kuburitsa kwekumanikidza sensor kune inozivikanwa referensi uye kugadzirisa zvinodiwa kubvisa chero mutsauko. Izvi zvinovimbisa kuti sensor inopa zviyero zvakarurama uye zvakavimbika.
Iyo Calibration process:
- Kugadzirira: Pamberi pekugadzirisa, zvakakosha kuti uunganidze michina inodiwa, kusanganisira referensi yekumanikidza sosi, calibration michina, uye yakakodzera calibration zviyero. Ita shuwa kuti iyo calibration nharaunda yakagadzikana uye haina chero kukanganisa.
- Zero Calibration: Iyo zero calibration inogadza yekutanga kuburitsa kweiyo pressure sensor kana pasina kudzvanywa kunoitwa. Iyo sensor inoratidzirwa kune referensi yekumanikidza zero uye yakagadziridzwa kuti ive nechokwadi chekubuda kwayo kunoenderana neinotarirwa zero kukosha.
- Span Calibration: Span calibration inosanganisira kushandisa inozivikanwa referensi kumanikidza kune sensor uye kugadzirisa kuburitsa kwayo kuti ienderane nemutengo unotarisirwa. Iyi nhanho inogadza mhinduro ye sensor uye mutsara pachiyero chekuyera.
- Data Analysis: Munguva yese yecalibration process, data inounganidzwa, kusanganisira iyo sensor yekubuda kuverenga uye inoenderana nereferensi kukosha. Iyi data inoongororwa kuti ione kushanda kwe sensor uye chero shanduko dzinodiwa.
Common Calibration Methods:
- Deadweight Tester: Iyi nzira inoshandisa zviyero zvakayerwa kushandisa kudzvanywa kunozivikanwa kune sensor. Iyo sensor inobuda inofananidzwa nehuwandu hunotarisirwa, uye kugadzirisa kunoitwa zvinoenderana.
- Pressure Comparator: Muenzanisi wekumanikidza anofananidza kuburitswa kwe sensor sensor kune referensi yekumanikidza inogadzirwa neiyo yakakwirira-chaiyo yekumanikidza sosi. Chero kukanganisa kunogadziriswa nekugadzirisa sensor.
- Reference Pressure Transducer: Iyi nzira inosanganisira kushandisa referensi yekumanikidza transducer ine inozivikanwa kururamisa kuyera kudzvanywa kunoshandiswa kune sensor. Iyo sensor inobuda inogadziriswa kuti ienderane nereferensi yekuverenga transducer.
- Software Calibration: Mamwe ma sensors ekumanikidza anopa software-based calibration, uko zvigadziriso zvinogona kuitwa zvemagetsi kuburikidza necalibration algorithms. Iyi nzira inobvumira kurongeka uye kwakaringana pasina kugadziridzwa kwemuviri.
Benefits of Calibration: Kugaro kuenzanisa kwekumanikidza sensors kunopa akati wandei mabhenefiti:
- Inovimbisa huchokwadi uye kuvimbika kweyero data.
- Inowedzera kuvimba mukuita kwe sensor uye inoderedza kuyerwa kusava nechokwadi.
- Inobatsira kusangana nezvinodiwa zvekutonga uye zviyero zveindasitiri.
- Inowedzera hupenyu hwe sensor nekuziva uye kugadzirisa chero nyaya pakutanga.
- Inovandudza maitiro ekushanda uye kubudirira nekuchengetedza zviyero zvakarurama.
Mhedziso: Calibrating pressure sensors yakakosha pakuona zviyero zvakaringana uye zvakavimbika mumashandisirwo akasiyana siyana eindasitiri. Nekutevera maitiro ekugadzirisa akakodzera uye kushandisa nzira dzakakodzera dzekugadzirisa, kuita uye hupenyu hurefu hwekumanikidza sensors kunogona kugadziridzwa. Kugaro gadzirisa hakungokwidziri kuyera chete asiwo kunoisa chivimbo mu data rinopihwa nemidziyo yakakosha iyi.
