Yuav ua li cas lub siab sensor ua haujlwm

1. Piezoresistive siab sensor. Kev ntsuas qhov ntsuas qhov ntsuas yog ib qho ntawm cov khoom tseem ceeb ntawm piezoresistive strain sensor. Lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm cov hlau tsis kam strain gauge yog tias cov strain resistance adsorbed ntawm lub hauv paus cov ntaub ntawv hloov nrog txhua yam deformation, uas feem ntau yog hu ua cov nyhuv strain.

2. Ceramic siab sensor. Ceramic siab sensor yog raws li cov nyhuv piezoresistive, qhov twg lub siab ncaj qha ua rau pem hauv ntej nto ntawm ceramic zaj duab xis, ua rau cov zaj duab xis deform me ntsis. Cov yeeb yaj kiab tuab yog luam tawm nyob rau sab nraum qab ntawm cov yeeb yaj kiab ceramic thiab txuas rau tsim tus choj Wheatstone. Vim lub piezoresistive nyhuv ntawm varistor, tus choj tsim ib tug siab linearity proportional rau lub siab. Lub teeb liab voltage kuj yog proportional rau qhov excitation voltage. Tus qauv teeb liab yog ntsuas rau 2.0/3.0/3.3mV/V raws li qhov siab ntau thiab yog sib xws nrog strain sensors.

3. Diffused silicon siab sensor: Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm diffused silicon siab sensor kuj yog raws li cov nyhuv ua haujlwm. Siv lub hauv paus ntsiab lus ntawm kev ua haujlwm tsis zoo, lub siab ntawm qhov ntsuas nruab nrab ncaj qha ua rau ntawm cov yeeb yaj kiab sensor (stainless steel lossis ceramic), kom cov yeeb yaj kiab tsim cov micro hloov pauv raws li qhov siab ntawm qhov nruab nrab, hloov pauv tus nqi ntawm lub sensor, kuaj pom qhov kev hloov pauv nrog cov kab hluav taws xob, thiab hloov cov qauv ntsuas lub teeb liab ntawm qhov sib thooj siab.

4. Sapphire siab sensor: Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm strain resistance, silicon sapphire raws li cov khoom siv hluav taws xob semiconductor rhiab heev, nrog cov yam ntxwv ntsuas tsis sib xws. Yog li ntawd, lub semiconductor rhiab heev lub ntsiab ua los ntawm silicon sapphire tsis rhiab rau qhov kub thiab txias hloov thiab muaj cov yam ntxwv ua haujlwm zoo txawm tias nyob rau hauv qhov kub thiab txias. Sapphire muaj zog tiv thaiv hluav taws xob; Tsis tas li ntawd, silicon sapphire semiconductor sensor tsis muaj pn drift.

5. Piezoelectric siab sensor: Piezoelectric nyhuv yog lub hauv paus ntsiab lus ntawm piezoelectric sensor. Piezoelectric sensors tsis tuaj yeem siv rau kev ntsuas zoo li qub vim tias tus nqi tom qab lub zog sab nraud tuaj yeem khaws cia tsuas yog thaum lub Circuit Court muaj infinite input impedance. Qhov no tsis yog qhov tseeb hauv kev xyaum, yog li piezoelectric sensors tsuas yog ntsuas qhov kev ntxhov siab. Daim ntawv thov: Siab sensor yog tsuas yog siv nyob rau hauv: lub tog raj kheej booster, supercharger, roj-kua booster lub tog raj kheej, roj-kua supercharger, xovxwm, compressor, cua txias cov khoom siv tub yees thiab lwm yam teb.
