Anthu ambiri nthawi zambiri amalakwitsa ma transmitters ndi ma sensor amphamvu omwewo, omwe amayimira masensa. Ndipotu iwo ndi osiyana kwambiri.
Chida choyezera chamagetsi mu chida choyezera kuthamanga chimatchedwa sensor sensor. Masensa a Pressure nthawi zambiri amakhala ndi masensa otanuka komanso masensa osuntha.
1. Ntchito ya chinthu chodziwikiratu ndi kupangitsa kuti mphamvu yoyezera igwire malo enaake ndikuyisintha kukhala yosasunthika kapena kupsyinjika, kenako ndikuisintha kukhala chizindikiro chamagetsi chokhudzana ndi kukakamizidwa ndi chinthu chodziwika bwino chosuntha kapena geji yamagetsi. Nthawi zina ntchito za zinthu ziwirizi zimaphatikizidwa, monga cholumikizira cholimba cha boma mu sensa ya piezoresistive.
2. Kupsyinjika ndi gawo lofunika kwambiri la ndondomeko yogwiritsira ntchito ntchito ndi ndege, ndege ndi mafakitale a chitetezo cha dziko. Sizingofunika kuyimitsa kuyeza kofulumira komanso kosunthika, komanso kuwonetsa ndi digito ndikujambulitsa zotsatira zake. Makina opangira makina opangira mafuta, mafakitale amafuta, mafakitale amagetsi ndi zitsulo ndi zitsulo zopangira zitsulo zimafunikiranso kufalitsa magawo opanikizika pakapita nthawi yayitali, ndikupempha kuti asinthe kupanikizika ndi magawo ena, monga kutentha, kuyenda ndi mamasukidwe akayendedwe, kukhala chizindikiro cha digito, tumizani ku kompyuta.
3. Pressure sensor ndi mtundu wa sensa yomwe imayamikiridwa kwambiri ndipo imapangidwa mwachangu. Kachitidwe kachitukuko ka sensor ya pressure ndikupititsa patsogolo kufulumira kwa kuyankha, kulondola komanso kudalirika, komanso kuwerengera kwathunthu ndi luntha. Ma sensor omwe ali ndi mphamvu zodziwika bwino akuphatikizapo capacitive pressure sensor, variable relucance pressure sensor, hall pressure sensor, optical fiber pressure sensor, resonant pressure sensor, etc.
Pali mitundu yambiri ya ma transmitters. Ma transmitter omwe amagwiritsidwa ntchito pazida zowongolera mafakitale makamaka amaphatikiza kutentha, ma transmitter, ma flow transmitter, transmitter yapano, ma voltage transmitter ndi zina zotero.
1. Chotumizira ndi chofanana ndi chokulitsa chizindikiro. AC220V transmitter yomwe timagwiritsa ntchito imapereka dc10v bridge voltage ku sensa, kenako imalandira chidziwitso, imakulitsa ndi kutulutsa 0V ~ 10V voltage kapena chizindikiro chamakono. Palinso ma transmitter ang'onoang'ono a DC24V, omwe amakhala akulu ngati masensa ndipo nthawi zina amayikidwa palimodzi. Nthawi zambiri, transmitter imapereka mphamvu ku sensa ndikukulitsa chizindikiro. Sensa imangotenga ma sign, monga strain gauge, yomwe imasintha chizindikiro chosunthira kukhala chizindikiro chokana. Inde, pali masensa opanda mphamvu, monga thermocouples ndi piezoelectric ceramics, zomwe zimagwiritsidwa ntchito nthawi zambiri.
2. Tagwiritsa ntchito mitundu yosiyanasiyana ya masensa othamanga, koma chotumizira sichinasinthidwe. Katswiri wamagetsi amazindikira chizindikiro cha kuthamanga, nthawi zambiri amatanthauza mita yoyamba. Kuthamanga kwa transmitter kumaphatikiza mita yoyambira ndi mita yachiwiri, ndikusintha chizindikiro chomwe chapezeka kukhala 4-20, 0-20 Ma kapena 0-5V, 0-10V ma siginecha, Mutha kumvetsetsa izi momveka bwino: sensa "imamva" yopatsirana. chizindikiro, ndipo chotumizira sichimangomva, komanso "chimakhala" chizindikiro chokhazikika ndiyeno "chimatumiza" kunja.
Pressure sensor nthawi zambiri imatanthawuza chinthu tcheru chomwe chimasintha siginecha yosinthika kukhala siginecha yofananira yokana kapena siginecha yamphamvu, monga piezoresistive element, piezocapacitive element, ndi zina. zinthu zotengera kupanikizika komanso kuwongolera dera. Nthawi zambiri, imatha kutulutsa siginecha yamagetsi yokhazikika kapena chizindikiro chapano muubwenzi wolumikizana ndi kukakamizidwa kuti itolere mwachindunji ndi zida, PLC, khadi yogulitsira ndi zida zina.
