K19 roj siab sensor 2897690 rau Cummins diesel cav accessories

1. Semiconductor varistor hom intake siab sensor.

(1) Kev ntsuas lub hauv paus ntsiab lus ntawm semiconductor piezoresistive siab sensor Lub semiconductor piezoresistive siab sensor siv cov nyhuv piezoresistive ntawm semiconductor los hloov siab rau hauv cov teeb liab voltage, thiab nws txoj cai muaj nyob rau hauv daim duab 8-21.

Semiconductor strain gauge yog ib yam ntawm cov ntsiab lus rhiab uas nws tus nqi kuj yuav hloov pauv tau thaum nws rub los yog nias.Cov kab ntsuas ntsuas tau txuas mus rau silicon diaphragm thiab txuas mus ua tus choj Wheston.Thaum lub silicon diaphragm yog deformed, txhua qhov ntsuas ntsuas raug rub los yog nias thiab nws cov kev hloov pauv, thiab tus choj yuav muaj cov khoom siv hluav taws xob sib thooj.

(2) Cov qauv ntawm piezoresistive intake siab sensor Cov muaj pes tsawg leeg ntawm cov semiconductor piezoresistive intake siab sensor yog qhia nyob rau hauv daim duab 8-22.Muaj cov silicon diaphragm nyob rau hauv lub siab hloov pauv lub ntsiab ntawm lub sensor, thiab compression deformation ntawm silicon diaphragm yuav tsim cov teeb liab sib xws.Ib sab ntawm silicon diaphragm yog lub tshuab nqus tsev, thiab sab nraud yog qhia nrog lub siab ntawm cov yeeb nkab.Thaum lub siab nyob rau hauv cov yeeb nkab hloov pauv, lub deformation ntawm silicon diaphragm yuav hloov raws li, thiab ib tug voltage teeb liab sib xws rau lub intake siab yuav raug generated.Qhov siab dua qhov inlet siab, qhov deformation ntawm silicon diaphragm ntau dua thiab ntau dua qhov tso zis siab ntawm lub sensor.

Lub semiconductor varistor hom intake yeeb nkab siab sensor muaj qhov zoo ntawm linearity zoo, cov qauv me me, qhov tseeb siab thiab cov yam ntxwv zoo.

1) Hom kev kuaj xyuas zaus: lub oscillation zaus ntawm lub oscillation Circuit Court hloov nrog tus nqi capacitance ntawm lub siab rhiab ntsiab, thiab tom qab rectification thiab amplification, mem tes teeb liab nrog zaus sib xws rau lub siab yog tso zis.

2) Voltage detection type: qhov kev hloov pauv ntawm tus nqi capacitance ntawm lub siab rhiab lub ntsiab yog modulated los ntawm cov cab kuj yoj thiab AC amplifier Circuit Court, demodulated los ntawm detector circuit, thiab ces lim los ntawm lim Circuit Court rau tso zis voltage teeb liab sib xws rau kev hloov siab.
