(Pfupiso tsananguro)Shandisa sensor kuyera hukama hwekumanikidza coefficient yemhepo; bvisa sensor kubva papombi yevacuum, uye uverenge inobuda voltage U0 ye sensor panguva ino. U. inokonzerwa nekudonha kwe sensor zero point uye kunzwa nekushanduka kwetembiricha.
Shandisa sensor kuyera hukama hwekumanikidza coefficient yemhepo; bvisa sensor kubva papombi yevacuum, uye uverenge inobuda voltage U0 ye sensor panguva ino. U. inokonzerwa nekudonha kwe sensor zero point uye kunzwa nekushanduka kwetembiricha. Bvisa Um kubva kuU., uye enzanisa mutsauko nemhepo yemhepo kuti uwane reshiyo pakati pevolti kukosha uye kukosha kwemhepo yemhepo, ndiko kuti, Kp. Calibration process inogumira pano, yobva yatanga zviri pamutemo: magetsi ekuisa ari 5.011V, dhigirii revacuum rinobva paShanduko kubva pa100 kuenda pa20, ne5 sechikamu chekuchinja. Yera iyo yakaenzana mhepo yekumanikidza coefficient kukosha inoenderana nedhigirii yega yega vacuum (Cherechedza: Iyo mhepo inotsikirira coefficient kukosha inoratidzwa patafura yakagadziriswa ne v/V = 0.02 kubvisa shanduko yehuwandu hwegirazi bubble uye tembiricha isina kuenzana ye gasi mumugero Iko kukanganisa kwakakonzerwa). Zvinogona kuonekwa kubva mudhata riri patafura kuti kukosha kwakayerwa kweiyo mhepo inotsikirira coefficient inoramba ichiwedzera nekudzikira kwedhigirii revacuum uye inotsauka zvakanyanya uye zvakanyanya kubva pakukosha kwayo kwechokwadi. Hukama huri pakati peshanduko mbiri idzi hunoratidzwa.
Chiyero chevacuum () iyo hukama hwekumanikidza coefficient yemhepo. Chiyero chevacuum () iyo hukama hwekumanikidza coefficient yemhepo. Chiyero chevacuum () iyo hukama hwekumanikidza coefficient yemhepo. Iyo yekupinza voltage inoshandurwa kubva ku2V kuenda ku9V. Kupesvedzera kwedhigirii revacuum pachiyero chakayerwa chehukama hwekumanikidza coefficient yemhepo inoratidza maitiro akafanana. . Semuenzaniso: kana magetsi ekuisa ari 8.005V, zviyero zvakayerwa zvedhigirii yevacuum uye hukama hwemhepo inotsikirira coefficient inoratidzwa muTafura 2. Mhedzisiro yedhigirii yevacuum pamhepo inoenderana nekumanikidza coefficient inoratidzwa.
Vacuum dhigirii () mhepo inotsikirira coefficient vacuum degree () mhepo inotsikirira coefficient vacuum dhigirii () mhepo hama yekumanikidza coefficient inogona kusvika kukosha kana vacuum dhigirii iri zana, uye kana magetsi ekuisa ari 8.005V, iyo vacuum degree vs. mhepo inodzvinyirira coefficient Kuedza kwakafanana kwakaitwa pane zvimwe zviridzwa mu laboratori, uye migumisiro yakafanana yakawanikwa. Kuti uderedze chikanganiso chinokonzerwa nedambudziko rekupomba kwevacuum, iyo yakayerwa mhepo inotsikirira coefficient kukosha inogona kuwanda neinopindirana vacuum Iyo dhigirii yekururamisa yemhedzisiro yekuedza. Tora dhigirii re95 semuenzaniso kuratidza: iyo dhigirii yevacuum inobata zvakananga U. Kana iyo vacuum degree iri 95, nhanho mushure mekupatsanurwa ne95 ndiyo nzira yekudhirowa dhizaini yePT kuti uwane kutsetseka (kutsetseka ndiyo hama. air pressure coefficient). Sezvo materu = A'/AT, mutsetse uye 'zvakatsetseka, mwoyo ttX 95 unogona kushandurwa kuti uwedzere zvakananga kuteremuka ne 95, nokuti nhanho P. yemutsara paY axis inoshanduka zvishoma, saka iwe inogona zvakananga Iyo yakawanikwa inoenderana nemhepo yekumanikidza coefficient kukosha inowedzerwa ne95 kugadzirisa kukanganisa kwakakonzerwa nekusakwana vacuum. Muchidimbu, kuwedzera iyo yakawanikwa inotsikirira mhepo coefficient kukosha kwayo inoenderana vacuum degree inogona kugadziriswa nekuda kwekusakwana vacuum. Error. Semuenzaniso, magetsi ekuisa i5.011V, iyo vacuum degree i95, uye yakayerwa mhepo inotsikirira coefficient value i0.0038899. Iko kukanganisa pakati pekukosha uku uye kukosha kwechokwadi ndeye 6.28. Kana kukosha uku kuchipetwa nedhigirii revacuum, iri 0.0038899X0. 95 = 0.0036954, iko kukanganisa pakati peiyo yakagadziriswa kukosha uye kukosha kwechokwadi kunoderedzwa kusvika 0.97. Mhedziso iyi inogona kuve kururamisa kwakanaka kumhedzisiro yekuyedza kana iyo vacuum degree isina kuderera. Kana iyo vacuum dhigirii yakanyanya kuderera, maitiro akasiyana-siyana Kufuridzirwa kwezvinhu pamigumisiro yekuedza kunonyanya kuoneka. Kungogadzirisa dhigirii revacuum hakugone kuwana mhedzisiro yekuyedza. Nekudaro, kazhinji, pombi yevacuum murabhoritari haizove yakaderera vacuum. Naizvozvo, pakuedza kwezuva nezuva kwevadzidzi, iyi mhedziso Iko kukanganisa kwakakonzerwa nekusakwana vacuum inogona kugadziriswa zvakanaka.
Kubva panhaurirano iri pamusoro, zvinogona kugumiswa kuti kudzika kwedhigirii revacuum yepombi yevacuum, kunowedzera kukosha kweyepakati pemhepo yemhepo yakayerwa nekuyedza, uye zvakanyanya kutsauka kubva pakukosha kwayo kwechokwadi 0.00366K-1. Shanduko yehuwandu hwakayerwa hwemhepo inoenderana nekumanikidza koefficient inosiyana nechiyero chevacuum Inowedzera uye inodzikira ichienderera, ichiratidza hukama hwemacurve neinoderera zvishoma nezvishoma mutsetse pakati pezviviri. Chiyedzo chinogona kugadzirisa mhedzisiro yekuyedza nekuwanza iyo yekupedzisira yakayerwa mhepo yehukama kumanikidza coefficient neinoenderana vacuum kukosha kwayo.
