Abantu abaninzi bahlala bephosisa abathumeli boxinzelelo kunye nezivamvo zoxinzelelo ezifanayo, ezimele abenzi boluvo. Enyanisweni, zahluke kakhulu.
Isixhobo sokulinganisa sombane kwisixhobo sokulinganisa uxinzelelo sibizwa ngokuba yinzwa yoxinzelelo. Abenzi boluvo boxinzelelo ngokubanzi baqulunqwe ngabenzi boluvo be-elastic kunye ne-displacement sensors.
1. Umsebenzi wento e-elastiki enovakalelo kukwenza uxinzelelo olulinganisiweyo lusebenze kwindawo ethile kwaye luyiguqulele kwi-displacement okanye uxinzelelo, kwaye emva koko uluguqule lube ngumqondiso wombane onxulumene noxinzelelo ngokususwa kwento ebuthathaka okanye igeyiji yoxinzelelo. Ngamanye amaxesha imisebenzi yezi zinto zimbini zidibeneyo, ezifana ne-solid-state pressure sensor kwi-piezoresistive sensor.
2. Uxinzelelo yiparameter yenkqubo ebalulekileyo kwinkqubo yokusetyenziswa kunye ne-aerospace, i-aviation kunye namashishini okukhusela kazwelonke. Ayifuni kuphela ukuyeka umlinganiselo okhawulezayo kunye noguquguqukayo, kodwa kunye nokubonisa ngedijithali kwaye urekhode iziphumo zomlinganiselo. I-automation ye-oil refineries enkulu, izityalo zamachiza, izityalo zamandla kunye nentsimbi kunye nezityalo zetsimbi nazo zifuna ukuhambisa iiparitha zoxinzelelo kwixesha elide, kunye nokucela ukuguqula uxinzelelo kunye nezinye iiparitha, ezifana nobushushu, ukuhamba kunye ne-viscosity, kwiimpawu zedijithali kunye zithumele kwikhompyuter.
3. Inzwa yoxinzelelo luhlobo lwenzwa oluxabiswa kakhulu kwaye luphuhliswe ngokukhawuleza. Umkhwa wokuphuhliswa kwenzwa yoxinzelelo kukuphucula ngakumbi isantya sokuphendula esiguqukayo, ukuchaneka kunye nokuthembeka, kunye nedijithali epheleleyo kunye nobukrelekrele. Iimpawu zoxinzelelo eziqhelekileyo ziquka i-capacitive pressure sensor, inzwa yoxinzelelo oluguquguqukayo, i-hall pressure sensor sensor, i-fiber optical inzwa yoxinzelelo, i-resonant pressure sensor, njl.
Kukho iintlobo ezininzi zee-transmitters. Ii-transmitter ezisetyenziswa kwizixhobo zolawulo lwemizi-mveliso ikakhulu zibandakanya i-transmitter yobushushu, i-pressure transmitter, i-flow transmitter, i-transmitter yangoku, i-voltage transmitter njalo njalo.
1. I-transmitter ilingana ne-amplifier yomqondiso. I-AC220V transmitter esiyisebenzisayo ibonelela nge-dc10v bridge voltage kwi-sensor, emva koko ifumana umqondiso wengxelo, ikhulise kwaye ikhuphe i-0V ~ 10V yombane okanye isignali yangoku. Kukwakho nezithutha ezincinci ze-DC24V, eziphantse zibe zikhulu njengezinzwa kwaye ngamanye amaxesha zifakwe kunye. Ngokuqhelekileyo, umthumeli unika amandla kwinzwa kwaye ikhulise umqondiso. I-sensor iqokelela kuphela izibonakaliso, ezifana ne-strain gauge, etshintsha isignali yokufuduka ibe ngumqondiso wokumelana. Kakade ke, kukho abenzi boluvo ngaphandle unikezelo lwamandla, ezifana thermocouples kunye piezoelectric ceramics, ezidla ngokusetyenziswa.
2. Sisebenzise iintlobo ezahlukeneyo zezivamvo zoxinzelelo, kodwa i-transmitter iphantse yatshintshwa. Inzwa yoxinzelelo ibona umqondiso woxinzelelo, ngokuqhelekileyo ubhekisela kwimitha yokuqala. Umthumeli woxinzelelo udibanisa imitha yokuqala kunye nemitha yesibini, kwaye uguqula umqondiso ofunyenweyo kwimigangatho ye-4-20, 0-20 Ma okanye i-0-5V, izibonakaliso ze-0-10V, unokuyiqonda ngokucacileyo: inzwa "ivakalelwa" idluliselwe. uphawu, kwaye umthumeli akayiva nje kuphela, kodwa "iba" isignali eqhelekileyo kwaye emva koko "iyithumele" ngaphandle.
Isivamvo soxinzelelo jikelele sibhekisa kwinto enovakalelo eguqula umqondiso woxinzelelo otshintshileyo ube ngumqondiso wokuchasa ohambelanayo okanye umqondiso wecapacitance, onje ngepiezoresistive element, piezocapacitive element, njl. njl. izinto ezinobunzima boxinzelelo kunye nesekethe yokulungelelanisa. Ngokubanzi, inokukhupha ngokuthe ngqo umqondiso oqhelekileyo wombane okanye umqondiso wangoku kubudlelwane bomgca kunye noxinzelelo lokuqokelela ngokuthe ngqo ngezixhobo, i-PLC, ikhadi lokufumana kunye nezinye izixhobo.
