Ultrasonic thickness gauge thickness calibration thiab ceev ntawm lub suab hloov
Vim muaj kev cuam tshuam ntawm cov yam ntxwv xws li ambient kub thiab kev khiav hauj lwm voltage, qee qhov ntsuas qhov system drift los ntawm lub sij hawm, yog li lub ntsuas yuav tsum tau calibrated rau thickness thaum ntsuas. Kev ua haujlwm calibration yog siv cov cuab yeej los ntsuas ib daim ntawm 5 hli tuab qauv kuaj daim, yog tias cov ntsuas ntsuas tsis sib npaug li 5 hli, lub thickness yuav tsum tau calibrated. Cov laus thickness gauges tau pom los ntawm kev kho cov pob qhov rooj potentiometer. Qhov kev tsim no tau ua tiav los ntawm qhov tseem ceeb ntawm cov thickness calibration, thaum koj xav tau calibrate, nias lub thickness calibration key, lub microcontroller executes lub thickness calibration txheej txheem, thiaj li hais tias qhov ntsuas tau thiab cov qauv thickness sib piv, raws li cov txiaj ntsig ntawm qhov sib ntxiv thiab rho tawm. ua tiav, ua kom tiav cov calibration.
Suab ceev teeb tsa
Ultrasonic thickness gauge nyob rau hauv ntsuas lub thickness ntawm cov ntaub ntawv sib txawv, vim ultrasonic tsis nyob rau hauv cov ntaub ntawv sib txawv propagation ceev yog txawv, yuav tsum tau teem lub ceev ntawm lub suab ntawm cov khoom, xws li steel ceev ntawm lub suab 5950m / s, zinc ceev ntawm lub suab 4170m / s. Qhov kev ua haujlwm no hauv cov cuab yeej qub yog ib qho khoom siv 3-ntsis BCD code disc keyboards thiab tuaj yeem ua cov txee preset los tswj cov rooj vag kom tiav cov naj npawb ntawm lub sijhawm ceev ntawm lub suab ntawm cov khoom, lub qhov rooj qhib lub rooj vag ntau. feem ntau, thiab cov khoom siv suab nrov qis, lub qhov rooj qhib qhov rooj ntau zaus. Rau cov ntaub ntawv uas tsis tshua muaj suab nrov, lub rooj vag qhib tsawg dua. Kev tsim cov cam khwb cia hlau, steel, aluminium, tooj liab, tooj dag, zinc, quartz iav, polyethylene, polyvinyl chloride, cuaj cov ntaub ntawv raug ceev ntawm lub suab, nyob rau hauv daim ntawv ntawm lub rooj rau hauv chav tsev cia, kev siv ceev ntawm lub suab teeb tsa los ntawm tus yuam sij rau xaiv, thiab tom qab ntawd los ntawm microcontroller's P1.7 chaw nres nkoj sau ntawm kev xa cov pulses kom rho tawm cov suav ntawm cov sij hawm nws tswj lub rooj vag kom qhib qhov ceev ntawm lub suab teev cov sij hawm, kom lub kev ua haujlwm ntawm kev ua haujlwm yog qhov yooj yim heev.
Kev kho suab nrawm
Lub suab ceev teeb tsa rau 9 cov khoom siv tau hais los saum toj no yog xaiv los ntawm lub suab ceev qhov tseem ceeb. Thaum ntsuas qhov tuab ntawm cov ntaub ntawv tsis raug, lub suab nrawm yog ua los ntawm ob lub luag haujlwm ntawm lub suab nrawm thiab suab nrawm. Nias tus yuam sij ntawm lub suab nrawm los yog lub suab nrawm qis, lub vijtsam LCD qhia tias lub suab nrawm tus nqi nce lossis txo qis, kom txog thaum nws hloov kho rau lub suab nrawm peb xav tau, lub sijhawm no, lub suab nrawm hloov kho yuav raug hloov kho rau lub suab nrawm. tus nqi ntawm lub suab ceev cia chav tsev yuav tsum tau siv.
