Nyob rau hauv cov txheej txheem ntawm kev lag luam kev tswj hwm, lub valve hluav taws xob ntaus ntawv yuav tsum tau ntsib qhov cuam tshuam ib puag ncig ntawm kev ua haujlwm sib txawv. Yog tias muaj teeb meem, tus neeg teb xov tooj yuav tsum txheeb xyuas qhov teeb meem hauv lub sijhawm thiab ua kom raug ntsuas kom paub txog kev ua haujlwm ruaj khov ntawm cov hluav taws xob actuator tswj qhov system thiab xyuas kom meej tias kev ua haujlwm tsis cuam tshuam. . Yog li ntawd, qhov tsis ua hauj lwm tsom xam thiab kev tshawb nrhiav haujlwm ntawm lub tshuab hluav taws xob valve actuator tsis tuaj yeem tsis quav ntsej.
Ntau zaus peb ntsib yog tias kev tswj xyuas qhov tseeb ntawm lub tshuab hluav taws xob actuator tsis raug lossis qhov yuam kev loj dhau. Lub sijhawm no, peb yuav tsum ua ntej txheeb xyuas seb puas muaj teeb meem nrog lub teeb liab input, thiab siv lub ammeter ncaj qha ntsuas qhov tseeb ntawm cov teeb liab tawm tswv yim. Yog tias nws muaj tseeb tias cov teeb liab tawm tswv yim tsis raug thiab yuav tsum tau kho, koj tuaj yeem hloov ncaj qha rau I / O module. Tom qab ntawd xyuas seb qhov kev tawm tswv yim ntawm qhov qhib thiab kaw tag nrho ntawm lub tshuab hluav taws xob valve yog qhov qub, thiab ntsuas seb cov lus tawm tswv yim yog 100% thiab 0%. Rau actuator tawm tswv yim teeb liab kho, cov kev hloov kho ntawm ntau lub npe sib txawv, thov mus saib cov khoom siv ntawm cov chaw tsim khoom siv. Kuj tseem nco ntsoov tias muaj kev sib raug zoo ntawm qhov chaw tuag ntawm lub tshuab hluav taws xob actuator thiab qhov tseeb. Nws yog ib qho tsim nyog los tshuaj xyuas seb nws puas yuav tshwm sim los ntawm qhov chaw tuag raug teeb tsa loj heev. Yog tias cov txheej txheem saum toj no tsis tuaj yeem tshem tawm qhov txhaum, koj yuav tsum rov pib kho mob stroke los daws nws.
