Electronic pressure sensor VG1092090311 yemafuta emumba inorema rori

Ndeapi marudzi akasiyana emagetsi masensa?

Kubva pamusimboti mukuru, tsinhiro isimba rakamira rinoshanda pamusoro pechinhu. Pressure = simba/nzvimbo. Semuyenzaniso, PSI ndiyo nhamba yemapaundi paskweya inch. Kana Pascal, imwe Newton pa square mita. Kune marudzi matatu ekumanikidza:

Geji pressure:

Iyi ndiyo yakajairika mhando yekumanikidza kana uchibata neinjiniya application. Gauge pressure ndiyo mutsauko uripo pakati pekumanikidzwa kwakapihwa neatmospheric pressure. Kana dzvinyiriro yacho yakakura kudarika mhepo yemuchadenga, inonzi positive overpressure. Kana iyo geji yakayerwa pressure isiri iyo, inodaidzwa kuti negative pressure kana partial vacuum.

Absolute pressure:

Iyi ndiyo poindi iri pamusoro pevacuum yakakwana. Kazhinji, ihwo huwandu hwegauge pressure pamwe neatmospheric pressure.

Musiyano wepressure: Uyu ndiwo mutsauko pakati pemapoinzi maviri kana pasina inozivikanwa vacuum kana vacuum yakazara.

Mamwe ese "mhando" dzekumanikidza (senge static pressure, negative pressure uye deflagration) ingori imwe yesarudzo dziri pamusoro, uye mazita adzo anoreva zvakananga mamiriro ekumanikidza.

Ndeapi marudzi ema sensors ekumanikidza aripo?

Idzo mhando dzema sensors ekumanikidza dzinosiyana zvakanyanya, asi dzinowanzo kupatsanurwa zvinoenderana nerudzi rwekumanikidza (sezvakataurwa pamusoro), nzira yekunzwa, inobuda chiratidzo chemhando uye yekuyera yepakati. Tarisa imwe neimwe zvakadzama:

Sensing nzira:

Chinangwa che tekinoroji tekinoroji iri nyore kwazvo, ndiko kuti, kushandura kudzvanywa kunoitwa pane sensor mechanic kuita chiratidzo chemagetsi chekubuda. Mhando dzesarudzo dze sensor dzinogona kusanganisira resistive, capacitive, resonant, piezoelectric, optical uye MEMS. Iyo sensor nzira inoshandiswa ichakanganisa kurongeka, kuvimbika, kuyera chiyero uye kuchinjika kune inoshanda nharaunda.

Zviratidzo zvekubuda:

Aya anowanzo ma transmitters, ayo anoburitsa zvinobuda kana masensa uye anoburitsa magetsi emagetsi, ayo anosiyana zvichienderana nedzvinyiriro inowanikwa.

Media type:

Nzvimbo yekushanda ichakanganisa rudzi rwekumanikidza sensor yaunosarudza. Semuenzaniso, kana sensor yako yekumanikidza ichashandisa corrosive media kana kushanda mune in-situ yekuchenesa sisitimu kana imwe nzvimbo yehutsanana, iwe unofanirwa kunyatso sarudza mhinduro inogona kuchengetedza yakasimba hutsanana nhanho yakagamuchirwa pasina kukuvadzwa nenharaunda. Iko kuyera mhinduro. Zvimwe zvinotariswa nevezvenhau zvinosanganisira kuti kuyerera kwemhepo imhepo, gasi, mvura, hydraulic kana pneumatic.
