Ukuhlaziywa Kwezimiso Kwezinhlobo Ezihlukahlukene Zezingcindezi

Inzwa yokucindezela iyinzwa esetshenziswa kakhulu emsebenzini wezimboni. Isetshenziswa kabanzi ezindaweni ezahlukahlukene zokulawula izimboni ezizenzakalelayo, ezibandakanya ukulondolozwa kwamanzi kanye namandla amanzi, ukuthuthwa kwesitimela, izakhiwo ezihlakaniphile, Ukulawulwa okuzenzakalelayo kokukhiqiza, i-aerospace, imboni yezempi, i-petrochemical, imithombo kawoyela, amandla kagesi, imikhumbi, amathuluzi emishini, amapayipi nezinye izimboni eziningi, Okulandelayo isingeniso esifushane semigomo nokusetshenziswa kwezinye izinzwa ezisetshenziswa kakhulu.

Inzwa yengcindezi iyidivayisi noma idivayisi engezwa amasiginali wokucindezela futhi iguqule amasiginali wokucindezela abe yisiginali yokukhipha kagesi esebenzisekayo ngokwemithetho ethile. Inzwa yengcindezi imvamisa iqukethe into ebucayi yengcindezi kanye neyunithi yokucubungula isignali.

1. Inzwa yengcindezi ye-Piezoresistive

Igeji yokuphikisana ngesinye sezinto eziyinhloko ze-piezoresistive strain sensor. Umgomo wokusebenza wegeji yensimbi yokumelana nensimbi yinto yokuthi inani lokumelana nokumelana kobunzima okufakwe ezintweni eziyisisekelo izinguquko ngokukhubazeka kwemishini, eyaziwa kakhulu njengomphumela wokuphikisana.

2. Inzwa yengcindezi yeCeramic

Inzwa yengcindezi ye-ceramic isuselwa kumphumela we-piezoresistive. Ingcindezi isebenza ngqo ebusweni bangaphambili kwe-ceramic diaphragm, kudala ukuguqulwa okuncane kwe-diaphragm. I-ressidior ejiyile yamafilimu iphrintwa ngemuva kwe-ceramic diaphragm futhi ixhunywe ebhulohweni le-Wheatstone. Ngenxa ye-piezoresistor Umphumela we-piezoresistive wenza ibhuloho likhiqize isignali yama-voltage eqondile ngokulingana nengcindezi nokulingana ku-voltage yokuthokozisa. Isignali ejwayelekile ilinganiselwa njenge-2.0 / 3. 0/3. 3mV / V ngokuya ebangeni lokucindezela, elingaqhathaniswa nokuhambisana nezinzwa ze-gauge.

3. Inzwa yengcindezi ye-silicon ehlukanisiwe

Umgomo wokusebenza wenzwa yengcindezi yokucindezela ye-silicon nayo ususelwa kumphumela we-piezoresistive. Kusetshenziswa umgomo womphumela we-piezoresistive, ingcindezi yesikhulu esilinganisiwe isebenza ngqo ku-diaphragm yenzwa (insimbi engenantambo noma i-ceramics), ukuze i- i-diaphragm ikhiqiza ukufakwa okuncane okulingana nengcindezi ye-medium. Yenza inani lokumelana lokushintsha kwenzwa, sebenzisa isekethe ye-elekthronikhi ukuthola lolu shintsho, futhi iguqule futhi ikhiphe isignali yesilinganiso esijwayelekile esihambelana nalesi ngcindezi.

4. Inzwa yengcindezi ye-piezoelectric

Umphumela we-piezoelectric umgomo oyinhloko wokusebenza we-piezoelectric sensor. Inzwa ye-piezoelectric ayinakusetshenziselwa ukulinganisa okumile, ngoba inkokhiso ngemuva kwamandla angaphandle igcinwa kuphela lapho isekethe ine-impedance yokufaka engapheli. Isimo sangempela asifani nalokhu, ngakho-ke lokhu kunquma ukuthi inzwa yengcindezi ye-piezoelectric ingalinganisa kuphela ukucindezeleka okunamandla.
