Vanhu vazhinji vanowanzo kanganisa madhiraivha uye ma sensors ekumanikidza akafanana, anomiririra masensa. Kutaura zvazviri, vakasiyana chaizvo.
Chimbo chekuyeresa chemagetsi chiri muchidziyo chekuyeresa chinonzi pressure sensor. Pressure sensors inowanzo umbwa ne elastic sensors uye displacement sensors.
1. Basa re elastic sensitive element nderekuita kuti dzvinyiriro yakayerwa iite pane imwe nzvimbo uye yoishandura kuita displacement kana strain, wozoishandura kuita chiratidzo chemagetsi chine chekuita nekumanikidzwa ne displacement sensitive element kana strain geji. Dzimwe nguva mashandiro ezvinhu zviviri izvi zvakabatanidzwa, senge solid-state pressure sensor mune piezoresistive sensor.
2. Dzvinyiriro chinhu chakakosha muitiro parameter mukushandisa nzira uye aerospace, avhiyesheni uye nyika kudzivirira maindasitiri. Izvo hazvidi chete kumira nekukurumidza uye zvine simba kuyerwa, asiwo nedhijitari kuratidza uye kurekodha zviyero zvekuyera. Iyo otomatiki yemafuta makuru ekunatsa, zvidyarwa zvemakemikari, zvidyarwa zvemagetsi uye simbi nesimbi zvidyarwa zvinodawo kufambisa maparamita ekumanikidza panguva yakareba, uye kukumbira kushandura kudzvanywa uye mamwe ma paramita, senge tembiricha, kuyerera uye viscosity, kuita masaini edhijitari uye vatumire kukombiyuta.
3. Pressure sensor imhando ye sensor inokosheswa uye inogadzirwa nekukurumidza. Iyo yekusimudzira maitiro ekumanikidza sensor ndeyekuenderera mberi nekuvandudza iyo ine simba yekupindura kumhanya, iko kurongeka uye kuvimbika, uye yakazara digitization uye hungwaru. Common pressure sensors dzinosanganisira capacitive pressure sensor, variable reluctance pressure sensor, hall pressure sensor, optical fiber pressure sensor, resonant pressure sensor, etc.
Kune akawanda marudzi ezvinotapurirana. Iwo ma transmitters anoshandiswa mumaindasitiri ekudzora zviridzwa anonyanya kusanganisira tembiricha transmitter, pressure transmitter, flow transmitter, current transmitter, voltage transmitter zvichingodaro.
1. Iyo inotumira yakaenzana nechiratidzo cheamplifier. Iyo AC220V transmitter yatinoshandisa inopa dc10v bhiriji voltage kune sensor, yobva yagashira chiratidzo chemhinduro, inokudza uye inoburitsa 0V ~ 10V voltage kana chiratidzo chazvino. Kune zvakare madiki ma transmitters eDC24V, anenge akakura semasensa uye dzimwe nguva anoiswa pamwechete. Kazhinji kutaura, iyo transmitter inopa simba kune sensor uye inosimudzira chiratidzo. Iyo sensor inongounganidza zvikwangwani, senge strain gauge, iyo inoshandura chiratidzo chekusimuka kuita chiratidzo chekupikisa. Zvechokwadi, kune ma sensors asina magetsi, akadai se thermocouples uye piezoelectric ceramics, iyo inowanzoshandiswa.
2. Isu takashandisa marudzi akasiyana-siyana ekumanikidza sensors, asi iyo transmitter haina kumbotsiviwa. Iyo yekumanikidza sensor inoona iyo yekumanikidza chiratidzo, kazhinji ichireva kune yekutanga mita. Iyo yekudzvanya inofambisa inosanganisa iyo yekutanga mita uye yechipiri mita, uye inoshandura iyo yakaonekwa chiratidzo kuita chiyero 4-20, 0-20 Ma kana 0-5V, 0-10V masaini, Unogona kunzwisisa izvi zvakajeka: iyo sensor "inonzwa" inotapurirwa. chiratidzo, uye mupepeti haangoinzwa chete, asiwo "inove" chiratidzo chakajairwa uyezve "inotumira" kunze.
Pressure sensor kazhinji inoreva chinhu chinonzwisa tsitsi chinoshandura chiratidzo chekudzvanya chachinja kuita chinoenderana chachinja chiratidzo chekupikisa kana capacitance chiratidzo, senge piezoresistive element, piezocapacitive element, nezvimwewo. pressure-sensitive elements uye conditioning circuit. Kazhinji, inogona kuburitsa zvakananga chiyero chemagetsi chiratidzo kana chiratidzo chazvino muhukama hwemutsara nekumanikidza kuunganidzwa kwakananga nezviridzwa, PLC, kadhi rekutora uye zvimwe zvishandiso.
