Txoj cai ua haujlwm
Lub siab sensor ntawm DWP-802 series yog tus qauv silicon cathode strain choj ua los ntawm lub tshuab nqus tsev vacuum-depositing ib tug semiconductor nto ntawm silicon substrate.Muaj ib txheej ntawm stainless hlau corrugated ntawv nruab nrab ntawm nws thiab ntsuas nruab nrab, thiab ib tug intermediary kua-silicone roj yog sau nyob rau hauv lub strain choj thiab stainless hlau corrugated ntawv.
Thaum lub siab P ua rau ntawm daim ntawv corrugated thiab raug xa mus rau tus choj strain los ntawm cov kua nruab nrab, qhov kev hloov ntawm tus choj cathode ua rau tus choj tshuav nyiaj li cas tso tawm cov khoom siv hluav taws xob sib npaug rau lub siab P. Ces, nws hloov mus rau 4. -20mA tso zis los ntawm lub teeb liab hloov dua siab tshiab thiab amplification Circuit Court thiab kub them nyiaj.
