Peripheral Electrical Circuit Troubleshooting
Ntsuas qhov ntsuas hluav taws xob siv hluav taws xob siv lub ntsuas hluav taws xob (DC teeb tsa) thiab xyuas kom tseeb tias qhov sib txawv tsawg dua lossis sib npaug rau ± 5%. Tshawb xyuas lub fais fab mov module thiab nrhiav oxidation los yog looseness nyob rau hauv lub terminals yog hais tias qhov voltage yog txawv.
Txheeb xyuas cov kab teeb liab: Rau hom kev sib txuas lus digital, siv lub oscilloscope los tshuaj xyuas cov ntawv waveforms rau pob ntawv poob lossis siab - cuam tshuam ntau zaus; rau cov cim analogue, ntsuas kab tsis kam (ib zaug-core Tsawg dua lossis sib npaug rau 10Ω / m) thiab ua kom cov ntaub thaiv npog av tiv thaiv tsawg dua lossis sib npaug rau 4Ω.
Txhawm rau tiv thaiv kev tiv thaiv drift coj los ntawm kev sib txuas slack, nruj cov terminals ntawm ob qho kawg ntawm lub sensor tag nrho.
Kev daws teeb meem ntawm Sensor Hardware
Static calibration: To replicate the target temperature and compare it with the sensor output, use a constant-temperature reference source (accuracy >0.02%). Calibrate raws li JB/T 8622 yog tias qhov hloov pauv ntau dua li qhov tso cai (feem ntau ± 0.2% FS); Yog tias calibration tsis ua tiav, hloov cov khoom.
Kev tshuaj xyuas qhov muag: Nrhiav cov pa roj carbon monoxide, scaling, los yog rwb thaiv tsev degradation ntawm kev tiv tauj probes; rau infrared uas tsis yog -ntau hom sib cuag, saib rau lub lens aging lossis blockages.
Kub-sensing element kev ua tau zoo: Ntsuas qhov kev tiv thaiv linearity tom qab disassembly; lub platinum resistor yog suav tias yog qub thiab yuav tsum tau hloov nrog ib tug sib npaug tivthaiv yog hais tias nws linearity sib txawv ntau tshaj ± 0.1% FS.
Teeb meem kev khiav hauj lwm tej yam kev mob thiab installation
Insertion qhov tob: Txhawm rau tiv thaiv qhov kub ntawm qhov sib txawv, kev tiv thaiv kev sojntsuam yuav tsum tau muab tso rau hauv nruab nrab yam tsawg tsib zaug ntawm txoj kab uas hla.
Compatibility nrog kev khiav hauj lwm tej yam kev mob: Xyuas kom meej tias qhov kub thiab txias yog nyob rau hauv rated txwv; nrhiav qhov txawv nruab nrab eddy tam sim no los yog loj electromagnetic cuam tshuam (los ntawm ze rau siab - khoom siv fais fab).
Txhim kho kev ntxhov siab: Tshawb xyuas yog tias lub hauv paus mounting tau txav los ntawm kev vibration lossis seb qhov kev sojntsuam puas cuam tshuam los ntawm kev overtightening.
Kev sib pauv kev sib txuas thaum lub sij hawm daws teeb meem tuaj yeem txo qis ntawm lub sijhawm xav tau los txheeb xyuas seb qhov teeb meem puas yog nrog lub ntsuas kub ntawm nws tus kheej, lub sensor, lossis cov cabling.
