Rau xyoo lawm, kev lag luam roj av thoob ntiaj teb tau txais yuav cov ntsuas cua txiav ua ntsuas kev lag luam rau kev ntsuas siab. Nws lub siab -} rhiab keeb yog ib tus resartz resonator, uas nws tau tso zis ntau dua nrog kev kub siab. Nws tseem muaj qhov xam tau qhov ua kom muaj kev rov ua dua thiab ruaj khov ntawm ib qho - siv lead ua plaub.

Peb SG - hp quartz crystal siab transducers tau hloov pauv, tshwj xeeb tshaj yog haum rau kev ua kom hnyav. Lub cev transducer yog ua los ntawm nickel- chromium {} {4 4}}

Cov koob no, tom qab ntsuas calibration thiab them nyiaj, tuaj yeem tso zis peb zaus. Txhua tus qauv yog nruab nrog ntau lub siab interfaces, haum rau ntau yam khoom siv OEM, thiab tau ua kom zoo dua, ruaj khov thiab siab {1} Precision siab lub siab thiab gases.

1 kev ntsuas ntau tshaj plaws yog tus nqi txwv tshaj uas ua rau muaj kev puas tsuaj rau cov khoom siv yuav tshwm sim thiab / lossis nws pab tau lub neej muaj txiaj ntsig. Ntaus ntawv ua tau zoo tsis tuaj yeem lees paub txog kev ua haujlwm sab nraud, peb tsis pom zoo kom ua haujlwm lub cuab yeej hauv thaj av no.

Ceev faj: DC {- coupled tawm yog raug rau kev puas tsuaj tas mus li yog tias tsis tsim nyog. Txhua zaus yuav tsum siv tam sim no - cov khoom siv fais fab tsawg los tiv thaiv hluav taws xob puas tsuaj.

2 lub siab thiab qhov kub siab zaus thiab kub zaus li ntau dua li yuav txawv ntawm transducer qauv.

3 ntev {{- Lub neej lub neej yuav raug txo yog qhov tsis zoo yog tias tsis zoo- cov ntaub ntawv siv tau thov ntawm qhov kub siab tshaj plaws.

4 kev ntsuas cov kev ntsuas tam sim no tsis muaj cov xov hlau tsis muaj cov zis tawm (tsis muaj kev thauj khoom).

5 teeb liab teeb liab tau tsav nrog ib cmos logic tsis. Siab thiab kub cov cim yog square tsis. Lub teeb liab siv hluav taws xob yog nyob ntawm kev thauj khoom; Ntawm 300PF cov amplitude yog txo qis.
