Mefuta eohle e arolelanoa 20 mm stroke (≤ DN 80), lintlha tsa PN 16 le 'mele oa tšepe ea tšepe, e nolofalletsang khetho ea actuator ea boholo bo le bong le lipeakanyo tse kopaneng tsa liphaephe ho pholletsa le 6.3 … 400 m³/h bokhoni .
Melemo ea Rōna ea Tlholisano
Joalo ka mohoebi ea inehetseng oa liindasteri, re fana ka mokhoa o ikhethileng oa ho reka thepa le litharollo tsa lits'ebeletso tsa bareki. Tsa rona mekhoa ea ho lefa e feto-fetohang ho amohela litlhophiso tsa phetisetso ea mohala le lits'ebeletso tsa mekitlane tse ikhethileng bakeng sa balekane ba amohetsoeng, ho tlosa litšitiso tsa lichelete litlhokong tse potlakileng tsa tlhokomelo. Re baballa thepa ea bohlokoa ea leano libakeng tsa kabo ea libaka, tse nolofalletsang ho tsamaisoa matsatsing a 5-7 a khoebo ho litsi tse ngata tsa indasteri lefatšeng ka bophara. Tsa rona marang-rang a pharaletseng a ho batla e fana ka liteishene tsa pele tsa kabo ea li-sensor tsa Europe le Asia, ho netefatsa ts'ebetso ea 'nete ea karolo ea Telemecanique ntle le lithibelo tsa sebaka. Mokhoa ona oa likanale tse ngata o tiisa ho ba teng nakong ea tšitiso ea phepelo ea thepa lefatšeng ka bophara. Baenjineri ba rona ba ts'ebeliso ba fana ka lipuisano tsa khetho ea li-sensor, lipalo tsa sebaka sa ho lemoha, le ts'ehetso ea ho kopanya, ho thusa ka tlhophiso ea logic ea taolo le ts'ebetso ea wiring. Ka litšebelisano tse tobileng tsa moetsi le thepa e hlophisitsoeng, re fana ka li-sensor tsa 'nete tsa Telemecanique tse nang le potoloho e potlakileng ea phethahatso le meaho ea litheko tsa tlholisano.
Bakeng sa liqotso tsa hanghang kapa therisano ea tekheniki, ka kopo ikopanye le sehlopha sa rona se inehetseng sa thekiso.
Mabapi le Rona
Re barekisi ba tsepamisitsoeng ba liindasteri-automation ba ikemiselitseng ho fana ka litharollo tsa 'nete tsa li-valve tsa Siemens ka lebelo, bonolo le boiphihlelo ba tekheniki.
