Umgaqo wokusetyenziswa kwenzwa yoxinzelelo

1. Izinto ezahlukeneyo

Kukho iintlobo ezininzi ze-mechanical sensors, ezifana ne-resonant strain gauge pressure sensor, i-semiconductor strain gauge sensor sensor, i-piezoresistive pressure sensor, i-inductive pressure sensor, i-capacitive sensor sensor, i-resonant pressure sensor kunye ne-capacitive acceleration sensor. Kodwa eyona nto isetyenziswa kakhulu yinzwa yoxinzelelo lwe-piezoresistive, enexabiso eliphantsi kakhulu, ukuchaneka okuphezulu kunye neempawu ezingcono zomgca.

2. Ukuqonda

Kwisivamvo soxinzelelo loxinzelelo lwe-decompression, siqala siqonde igeyiji yoxinzelelo lokumelana le nto. Igeyiji yoxinzelelo lokumelana sisixhobo esibuthathaka esiguqula utshintsho loxinzelelo kwindawo elinganisiweyo ibe ngumqondiso wombane. Ngenye yezinto eziphambili ze-piezoresistive strain sensor. Ezona zigeyiji zokuxhathisa zisetyenziswa kakhulu ziigeyiji zoxinzelelo lwesinyithi kunye neegeyiji zoxinzelelo lwesemiconductor. Kukho iindidi ezimbini zegeyiji yokumelana nentsimbi: igeyiji yocingo kunye nefoyile yentsimbi. Ngokuqhelekileyo, i-gauge yoxinzelelo ibotshelelwe ngokuqinileyo kwi-matrix yoxinzelelo lomatshini yi-arhente ekhethekileyo yokudibanisa. Xa uxinzelelo lwe-matrix lutshintsha, i-gauge ye-resistance gauge iphinda iguqule, ukwenzela ukuba ixabiso lokumelana ne-strain gauge litshintshe, kwaye i-voltage isetyenziswe kwiinguqu zokumelana. Ixabiso lokuchasana le gauge yoxinzelelo ngokuqhelekileyo lincinci xa ligxininisekile, kwaye le gauge ye-strain ngokuqhelekileyo iqulunqwe yi-A / D bridge, kwaye ikhuliswe yi-amplifier yesixhobo esilandelayo, kwaye emva koko idluliselwe kwisiphaluka sokucubungula (ngokuqhelekileyo i-A / D ukuguqulwa kunye CPU) ukubonisa okanye indlela yokulawula.
