Pa ntchito zamakono zamafakitale, masensa oyambitsa zinthu kuti azindikire malo ndi ofunikira kwambiri. Poyerekeza ndi ma switch amakina, amapanga zinthu zabwino kwambiri: kuzindikira popanda kukhudza, kusawonongeka, kusintha pafupipafupi, komanso kusinthasintha kolondola kwambiri. Kuphatikiza apo, sakhudzidwa ndi kugwedezeka, fumbi, ndi chinyezi. Masensa oyambitsa zinthu amatha kuzindikira zitsulo zonse popanda kukhudzana ndi thupi. Amatchedwanso ma switch oyambitsa zinthu kapena masensa oyambitsa zinthu.
Mapulogalamu Osiyanasiyana
Masensa oyendetsera zinthu amagwiritsidwa ntchito kwambiri, makamaka pozindikira zigawo zachitsulo ndi kuyang'anira malo. Ndi oyenera makamaka mafakitale monga magalimoto, kukonza chakudya, ndi zida zamakina. Ma switch oyendetsera zinthu amathanso kugwiritsidwa ntchito m'malo oopsa, komwe ukadaulo wa NAMUR kapena nyumba zolimba zimatsimikizira chitetezo cha kuphulika.
Nyumba ya masensa nthawi zambiri imapangidwa ndi mkuwa wopangidwa ndi nickel kapena chitsulo chosapanga dzimbiri, ndipo chomalizachi chimakhala cholimba kwambiri ku chinyezi chambiri komanso malo owononga. Chifukwa cha kapangidwe kake kolimba komanso kugwira ntchito kosawonongeka, masensa awa ndi njira yodalirika yogwiritsira ntchito zinthu zambiri. M'malo omwe ali ndi ma spatter, masensa oyambitsa amathanso kukhala ndi zokutira zapadera, monga PTFE (Teflon) kapena zinthu zina zofanana, kuti zikhale zolimba.
Mfundo Yogwira Ntchito ya Masensa Othandizira
Ma sensor oyambitsa zinthu amazindikira zinthu zachitsulo mosakhudzana ndi kukhudza zinthu mwa kuzindikira kusintha kwa mphamvu yamagetsi. Amagwira ntchito motsatira mfundo ya mphamvu yamagetsi: mphamvu yamagetsi ikasinthasintha, imayambitsa magetsi mu kondakitala.
Nkhope yogwira ntchito ya sensa imatulutsa mphamvu yamagetsi yamagetsi yothamanga kwambiri. Chinthu chachitsulo chikayandikira, chinthucho chimasokoneza gawoli, zomwe zimapangitsa kuti zinthu zisinthe mosavuta. Sensa imasintha kusinthaku ndikukusintha kukhala chizindikiro chosinthira, kusonyeza kuti chinthucho chilipo.
Masensa oyambitsa zinthu amabwera m'njira zosiyanasiyana, iliyonse ili ndi mtunda wosiyana wosinthira. Kuzindikira kwakutali kumakulitsa kugwiritsa ntchito kwa sensa—makamaka kothandiza pamene kuyikira mwachindunji pafupi ndi chinthu chomwe mukufuna sikungatheke.
Mwachidule, masensa oyambitsa zinthu amapereka ntchito yolondola kwambiri komanso yodalirika. Mfundo zawo zogwirira ntchito popanda kukhudza komanso njira zosiyanasiyana zopangira zinthu zimapangitsa kuti zikhale zofunika kwambiri pa ntchito zodzipangira zokha zamafakitale.
Mapangidwe osiyanasiyana amathandiza kuzindikira mosavuta
Chifukwa cha kulekerera kochepa kwa muyeso, masensa oyambitsa amatha kutsimikizira kuti akupezeka modalirika. Mtunda wosinthira wa masensa oyambitsa umasiyana malinga ndi kapangidwe kake. Mwachitsanzo, mtunda wosinthira wa masensa akuluakulu oyambitsa ukhoza kufika mpaka 70mm. Masensa oyambitsa amabwera m'mitundu yosiyanasiyana yokhazikitsa: Masensa oyambitsa amatuluka ndi pamwamba pa malo okhazikitsa, pomwe masensa osatulutsa amatuluka mamilimita angapo, zomwe zimapangitsa kuti pakhale mtunda wosinthira waukulu.
Mtunda wozindikira wa masensa oyambitsa umakhudzidwa ndi coefficient yokonza, ndipo mtunda wosinthira wa zitsulo zina kupatula chitsulo ndi wocheperako. LANBAO imatha kupereka masensa oyambitsa omwe sali ochepetsedwa ndi correction factor ya 1, omwe ali ndi mtunda wosinthira wofanana wa zitsulo zonse. Masensa oyambitsa nthawi zambiri amagwiritsidwa ntchito ngati PNP/NPN nthawi zambiri amatseguka kapena nthawi zambiri amatsekedwa. Ma Model okhala ndi analog output amatha kukwaniritsa zofunikira zapadera.
Yolimba komanso yodalirika - Chitetezo chapamwamba choyenera malo ovuta
Popeza kuti masensawa ali ndi kutentha kwakukulu komanso chitetezo champhamvu, ndi oyenera kugwiritsidwa ntchito m'malo ovuta kwambiri m'mafakitale. Pakati pawo, masensa oyambitsa omwe ali ndi chitetezo cha IP68 amathanso kutseka kwambiri m'mafakitale monga chakudya, mankhwala, ndi makina omanga. Kutentha kwawo kogwirira ntchito kumatha kufika 85 °C osapitirira apo.
Cholumikizira cha M12 chimatsimikizira kuyika kosavuta
Cholumikizira cha M12 ndiye njira yodziwika bwino yolumikizira masensa chifukwa imatha kuonetsetsa kuti kuyika kwake kuli mwachangu, kosavuta komanso kolondola. LANBAO imaperekanso masensa oyambitsa magetsi okhala ndi maulumikizidwe a chingwe, omwe nthawi zambiri amayikidwa m'mapulogalamu omwe ali ndi malo ochepa. Chifukwa cha kugwiritsidwa ntchito kwake kwakukulu komanso kudalirika kwakukulu, masensa oyambitsa magetsi ndi zinthu zofunika kwambiri muukadaulo wamakono wodziyimira pawokha ndipo amagwiritsidwa ntchito m'magawo ambiri amafakitale.
