Cov txheej txheem rau kev txiav txim siab qhov zoo ntawm Kev Tiv Thaiv Kev Tiv Thaiv Tom Qab Photoelectric Sensors
I. Cov tsos mob thiab cov qauv (Kev txiav txim siab ntxov ntxov, zam kev ua haujlwm tsis zoo)
Optical Lens:Lub lens yog pob tshab, tsis muaj khawb, fogging, thiab impurities, nrog txheej txheej; Cov khoom lag luam tsis zoo yog qhov ua rau yellowing, lub teeb xa hluav taws xob attenuation, thiab ntev - lub sij hawm rhiab heev poob.
Spot Structure:High- cov khoom zoo muaj cov me me / duab plaub nrog cov npoo ntshiab; Cov khoom lag luam muaj qhov sib txawv me me thiab qhov hnyav astigmatism, yooj yim ua rau kev tshawb pom tsis tseeb ntawm qhov ze.
Housing thiab Adjustment Knob:Lub vaj tse yog nplaim taws-retardant thiab aging-resistant, nrog rau cov damping thiab meej scale hloov; Cov pob qhov tsis zoo yog xoob, muaj qhov sib txawv loj, thiab tsis muaj kev hloov kho gradients.
Txuas / Interface:Pins thiab cable shielding yog zoo lawm, thiab waterproof sealing yog nruj; cov qauv kev lag luam muaj kev sib txuas rov qab thiab luv luv - cov qauv tiv thaiv hluav taws xob.
II. Core Performance Testing (Qhov tseem ceeb tshaj plaws, sib txawv ntawm qhov zoo thiab qhov tsis zoo)
1. Kev Txhaum Tom Qab Txiav -Tshem Tawm Qhov Ncauj (Core Indicator) Kho lub sensor txoj hauj lwm thiab siv cov ntaub ntawv muaj zog xws li daim ntawv dawb, daim ntaub dub, lossis cov hlau saum npoo kom txav lub sensor los ntawm qhov deb mus rau ze rau kev sim.
Zoo heev: Ua tiav undetectable tiv thaiv cov keeb kwm yav dhau los sab nraum qhov teeb pom kev deb; meej thiab txiav txim siab ciam teb ntawm qhov tseem ceeb nyob deb.
Tsis zoo: Kev nkag mus rau hauv kev tawm tsam tshwm sim txawm tias muaj keeb kwm muaj zog me ntsis; cuav triggering tshwm sim ntawm qhov ntev; blurry ntawm qhov tseem ceeb deb, flickering.
2. Xim txawv / Xim Deviation Adaptability
Kev tiv thaiv keeb kwm yav dhau yuav tsum hloov mus rau cov hom phiaj xim sib txawv:
Zoo heev: Qhov sib txawv me me hauv kev tshawb pom qhov deb ntawm cov khoom dub, dawb, thiab grey ntawm tib qhov deb.
Tsis zoo: Tsuas pom lub teeb - xim, cov khoom muaj kev cuam tshuam heev; Kev kuaj pom qhov deb ntawm cov khoom tsaus ntuj raug txo qis, ua rau muaj kev kuaj pom tsis zoo.
3. Rov ua dua & Hysteresis
Rov ua dua kev sim ntawm cov ntsiab lus tseem ceeb:
Zoo heev: Cov kev hloov pauv huv huv, hysteresis tsawg kawg nkaus, thiab qhov yuam kev tsawg tsawg hauv txoj haujlwm rov tshawb pom dua.
Tsis zoo: Jitter thiab nquag flickering nyob rau hauv ntau yam tseem ceeb; nquag mus malfunctions.
4. Spot Size thiab Anti-Stray Light Ability
Me me qhov me me tsim: Tsim nyog rau cov khoom me me thiab nqaim- pom ntug, tiv thaiv kev cuam tshuam los ntawm cov khoom nyob ib puag ncig.
Anti- teeb pom kev zoo: Tsis txhob ua yuam kev nyob rau hauv lub teeb muaj zog, teeb pom kev zoo sab hauv tsev, los yog diffuse reflection ib puag ncig; inferior khoom tsis ncaj qha nyob rau hauv lub teeb muaj zog.
III. Hluav taws xob thiab Circuit Court Stability
Dav Voltage Compatibility:Txuj kev lag luam DC10 ~ 30V dav voltage ntau yam, ruaj khov tso zis nyob rau hauv ± 15% voltage fluctuation ntau.
Output Signal: NPN / PNP tso zis tsis muaj suab nrov, tsis muaj hluav taws xob poob lossis overheating nyob rau hauv load.
Kev tiv thaiv muaj nuj nqi:High-cov khoom lag luam zoo tau tsim- hauv kev tiv thaiv kev tiv thaiv rov qab, kev tiv thaiv overcurrent, thiab kev tiv thaiv surge; Cov khoom lag luam tsis muaj kev tiv thaiv, thiab kev xaim tsis raug yuav ua rau muaj hluav taws xob ncaj qha.
Teb ceev:High- qauv ceev muaj microsecond- theem teb, ua kom tsis muaj kev kuaj pom hauv siab - ceev conveyor siv thiab siab - ceev suav; qis- cov khoom kawg muaj cov lus teb qeeb thiab ua tsis tiav hauv siab - cov xwm txheej ceev.
