Load Cell Troubleshooting Steps – Kev ncaj ncees ntawm tus choj

Test: Kev ncaj ncees ntawm tus choj

Txheeb xyuas tus choj kev ncaj ncees los ntawm kev ntsuas cov tswv yim thiab cov zis tawm thiab qhov sib npaug ntawm tus choj. Tshem tawm lub xov tooj ntawm tes los ntawm lub thawv sib txuas lossis ntsuas ntsuas.

Input thiab output resistances yog ntsuas nrog ib tug ohmmeter ntawm txhua khub ntawm input thiab output leads. Sib piv cov kev tawm tswv yim thiab cov zis tawm tsam rau daim ntawv pov thawj calibration qub (yog tias muaj) lossis cov ntaub ntawv tshwj xeeb.

Choj tshuav nyiaj li cas yog tau los ntawm kev sib piv cov - tawm mus rau - tawm tswv yim thiab - tawm mus rau + tawm tswv yim tiv thaiv. Qhov sib txawv ntawm ob qhov tseem ceeb yuav tsum tsawg dua lossis sib npaug rau 1Ω.

Ntsuam xyuas:

Cov kev hloov hauv kev tiv thaiv choj los yog kev sib npaug ntawm tus choj feem ntau yog tshwm sim los ntawm kev sib txuas lossis hluav taws kub, cov khoom siv hluav taws xob tsis zoo, lossis cov khoom siv luv luv. Qhov no tuaj yeem tshwm sim los ntawm overvoltage ( xob laim lossis vuam), lub cev puas tsuaj los ntawm kev poob siab, kev vibration lossis qaug zog, kub dhau los lossis kev tsim khoom tsis sib xws.
Test: Impact Resistance

Lub load cell yuav tsum tau txuas nrog lub zog ruaj khov, zoo dua qhov ntsuas ntawm lub xov tooj ntawm tes nrog rau qhov kev tawm dag zog tsawg kawg yog 10 volts. Disconnect tag nrho lwm cov load cell ntawm ib tug ntau load cell system.

Txuas lub voltmeter mus rau cov khoom tso tawm thiab coj mus rhaub cov khoom thauj me me nrog lub mallet kom vibrate me ntsis. Thaum kuaj qhov poob siab tsis kam ntawm lub peev xwm load hlwb, kev saib xyuas hnyav yuav tsum tsis txhob overload lawv.

Saib xyuas cov ntawv nyeem thaum kuaj. Kev nyeem ntawv yuav tsum tsis txhob ua yuam kev, nws yuav tsum nyob ruaj khov thiab rov qab mus rau qhov qub xoom nyeem ntawv.

Ntsuam xyuas:

Kev nyeem ntawv tsis zoo yuav qhia tau tias muaj kev sib txuas hluav taws xob tsis zoo lossis kev puas tsuaj ntawm cov kab mob sib kis thiab cov khoom siv vim muaj hluav taws xob hloov pauv.
