LIMIT SWITCH BOX

VALVE POSITION MONITOR

VALVE TRAVEL SWITCH

Lub thawv hloov pauv tseem hu ua Valve Position Monitor lossis lub valve mus ncig. Nws yog ib qho cuab yeej uas qhia (reacts) lub valve hloov raws li txoj cai. Ntawm qhov chaw ze, peb tuaj yeem soj ntsuam qhov qhib / kaw lub xeev tam sim no ntawm lub valve los ntawm "OPEN" / "CLOSE" ntawm qhov txwv hloov. Thaum lub sijhawm tswj cov chaw taws teeb, peb tuaj yeem paub qhov tam sim no qhib / kaw lub xeev ntawm lub valve los ntawm qhov qhib / kaw lub teeb liab pub rov qab los ntawm kev txwv kev hloov pauv pom ntawm lub vijtsam tswj.

Lub valve txwv hloov pauv yog ib qho khoom siv tswj tsis siv neeg uas hloov lub tshuab teeb liab mus rau hauv cov teeb liab hluav taws xob. Nws yog siv los tswj txoj haujlwm lossis mob stroke ntawm qhov txav mus los thiab paub txog kev tswj hwm qib, kev tswj xyuas qhov chaw thiab kev txheeb xyuas lub xeev. Nws yog ib qho uas feem ntau siv cov khoom siv hluav taws xob qis tam sim no uas ua lub luag haujlwm tseem ceeb hauv kev tswj tsis siv neeg. Lub valve txwv kev hloov (Position Monitor) yog ib qho cuab yeej siv rau lub valve txoj hauj lwm tso saib thiab teeb liab tawm tswv yim hauv kev tswj tsis siv neeg. Nws outputs qhib los yog kaw txoj hauj lwm ntawm lub valve raws li ib tug hloov ntau npaum (sib cuag) teeb liab, uas yog qhia los ntawm lub on-site qhia lub teeb los yog txais los ntawm cov kev pab cuam tswj los yog lub computer coj mus kuaj los tso saib qhov qhib thiab kaw txoj hauj lwm ntawm lub valve, thiab ua qhov kev pab cuam tom ntej tom qab kev pom zoo. Qhov kev hloov no feem ntau yog siv rau hauv kev tswj hwm kev lag luam, uas tuaj yeem txwv txoj haujlwm lossis mob stroke ntawm cov neeg kho tshuab txav thiab muab kev tiv thaiv kev txwv kom ntseeg tau.

Muaj ntau txoj hauv kev ua haujlwm thiab hom kev txwv valve, suav nrog cov kev txwv tsis pub siv tshuab thiab cov kev txwv sib thooj. Mechanical limit switches txwv kev txav mus los ntawm kev sib cuag lub cev. Raws li cov qauv sib txawv ntawm qhov kev txiav txim, lawv tuaj yeem muab faib ntxiv rau hauv kev ua yeeb yam ncaj qha, dov, micro-motion thiab sib xyaw ua ke. Cov kev txwv qhov sib thooj, tseem hu ua contactless mus txawv tebchaws keyboards, yog cov tsis sib cuag txhais tes keyboards uas ua rau kev ua los ntawm kev kuaj lub cev hloov (xws li eddy tam sim no, sib nqus teb hloov, hloov capacitance, thiab lwm yam) generated thaum ib yam khoom mus txog. Cov keyboards no muaj cov yam ntxwv ntawm kev tsis sib cuag, ua haujlwm ceev ceev, ruaj khov teeb liab tsis muaj pulsation, txhim khu kev lag luam thiab kev pab cuam lub neej ntev, yog li lawv tau siv dav hauv kev tsim khoom.
