Hauv cov khoom siv hauv kev lag luam, lub siab hloov pauv yog ib feem ntau. Nws txoj haujlwm yog qhov yooj yim: thaum lub siab nce mus txog ib qho nqi, qhov hloov mus ua haujlwm, tswj cov khoom pib lossis nres. Txawm li cas los xij, ntau tus neeg tsis paub tias qhov hloov pauv siab tau tuaj nyob hauv peb hom:txhua yam, electronics nrog cov zaub, thiabhluav taws xob tsis muaj cov duab digital. Niaj hnub no, peb yuav piav qhia qhov sib txawv ntawm peb hom kev hloov siab no hauv txoj hauv kev yooj yim tshaj plaws, pab koj xaiv qhov tsim nyog tshaj plaws rau koj daim ntawv thov.
I. Qhov txawv ntawm Txoj Cai Ua Haujlwm
1. Mechanical Pressure Switch:
Nyob rau hauv ib tug mechanical siab hloov, muaj ib tug caij nplooj ntoos hlav thiab ib tug diaphragm. Thaum lub siab yog thov, lub diaphragm thawb tawm tsam lub caij nplooj ntoos hlav. Thaum lub siab ncav cuag qhov taw tes, lub caij nplooj ntoos hlav yog compressed mus rau ib qho kev kawm, uas ua rau lub qhov hloov, ua tiav qhov kev txiav txim rau / tawm. Tag nrho cov txheej txheem tso siab rau kev xa mus rau lub cev thiab tsis muaj cov khoom siv hluav taws xob.
2. Electronic Pressure Switch with Digital Display:
Lub tshuab hluav taws xob hloov hluav taws xob nrog cov duab digital muaj lub siab sensor thiab lub siab txias hauv Circuit Court. Lub sensor tsis tu ncua hnov qab hloov pauv thiab hloov lub siab mus rau hauv lub teeb liab hluav taws xob. Lub siab txias Circuit Court sib piv cov teeb liab no nrog rau tus neeg siv-set siab tus nqi. Thaum kawg, cov lus txib yog tso tawm los ntawm kev hloov hluav taws xob. Qhov sib txawv loj tshaj plaws los ntawm kev hloov kho tshuab yog tias nws muaj lub vijtsam digital built-in uas qhia txog tus nqi siab tam sim no hauv lub sijhawm tiag tiag, nrog rau ntau lub nyees khawm rau kev teeb tsa ntawm qhov chaw.
3. Electronic Pressure Switch tsis muaj Digital Display:
Lub tshuab hluav taws xob hloov hluav taws xob tsis muaj cov duab digital muaj cov qauv sab hauv zoo ib yam li cov qauv nrog cov zaub: nws suav nrog lub ntsuas hluav taws xob thiab lub tshuab ua kom txias txias, thiab muaj tib lub peev xwm txiav txim siab. Txawm li cas los xij, nws tsis muaj qhov screen thiab tsis muaj khawm. Kev teeb tsa Parameter feem ntau yog ua los ntawm RS485 kev sib txuas lus siv lub computer, PLC, lossis HMI xa cov lus txib. Cov kev ntsuas kuj tseem tuaj yeem nyeem los ntawm kev sib txuas lus lossis los ntawm 4-20 mA analog tso zis txuas nrog cov zaub. Qhov sib txawv tseem ceeb ntawm cov khoom siv hluav taws xob nrog cov zaub yog tias cov ntawv tsis yog cov duab feem ntau yog qhov sib txuam ntau dua, ua rau nws tsim nyog rau cov chaw kaw lossis qhov chaw nyob qhov twg ntawm qhov chaw hloov kho tsis yooj yim, thaum tseem tso cai rau cov chaw taws teeb nyeem ntawv thiab hloov kho.
Cov lus hauv qab no qhia meej meej piv rau peb hom:
