Ma Inductive Proximity Sensors - Zida Zofunikira za Industrial Automation

Ntchito Zosiyanasiyana

Masensa ochititsa chidwi amagwiritsidwa ntchito kwambiri, makamaka pozindikira chigawo chachitsulo ndikuwunika malo. Ndioyenera makamaka kumafakitale monga magalimoto, kukonza chakudya, ndi zida zamakina. Kusintha kwapafupi kwa inductive kungathenso kutumizidwa kumadera owopsa, kumene teknoloji ya NAMUR kapena nyumba zolimba zimatsimikizira chitetezo chambiri cha kuphulika.

Nyumba za masensawo nthawi zambiri zimapangidwa ndi mkuwa wokutidwa ndi faifi tambala kapena chitsulo chosapanga dzimbiri, ndipo zomalizirazo zimagonjetsedwa makamaka ndi chinyezi chambiri komanso malo owononga. Chifukwa cha ntchito yawo yolimba yomanga komanso yosavala, masensa awa amakhala ngati yankho lodalirika pamapulogalamu ambiri. M'malo okhala ndi zowotcherera spatter, masensa inductive amathanso kukhala ndi zokutira zapadera, monga PTFE (Teflon) kapena zida zofananira, kuti zikhale zolimba.

Mfundo Yogwira Ntchito ya Sensors Inductive

Masensa ochititsa chidwi amazindikira zinthu zachitsulo m'njira yosalumikizana pozindikira kusintha kwa gawo la electromagnetic. Amagwira ntchito potengera mfundo ya electromagnetic induction: mphamvu ya maginito ikasinthasintha, imapangitsa mphamvu yamagetsi mu conductor.

Nkhope yogwira ntchito ya sensor imatulutsa gawo lamagetsi lamagetsi apamwamba kwambiri. Chinthu chachitsulo chikayandikira, chinthucho chimasokoneza mundawu, zomwe zimapangitsa kuti zisinthe. Sensa imayendetsa kusinthika uku ndikuisintha kukhala chizindikiro chosinthira, kuwonetsa kukhalapo kwa chinthucho.

Masensa ochititsa chidwi amabwera m'mapangidwe osiyanasiyana, iliyonse ili ndi mtunda wosiyana wosinthira. Kutalikirana kozindikira kumakulitsa magwiridwe antchito a sensayo - zothandiza makamaka ngati kuyimitsa molunjika pafupi ndi chinthu chomwe mukufuna sikungatheke.

Mwachidule, masensa inductive amapereka mwatsatanetsatane kwambiri ndi ntchito yodalirika. Mfundo zawo zogwirira ntchito zopanda kulumikizana komanso zosankha zosiyanasiyana zamapangidwe zimawapangitsa kukhala ofunikira kwambiri pakugwiritsa ntchito makina opanga mafakitale.

Mapangidwe osiyanasiyana amathandizira kuzindikira kosinthika

Chifukwa cha kulolerana kwakung'ono, masensa ochititsa chidwi amatha kuonetsetsa kuti apezeka odalirika. Mtunda wosinthira wa masensa ochititsa chidwi umasiyanasiyana kutengera kapangidwe kake. Mwachitsanzo, mtunda wosinthika wa masensa akuluakulu ochititsa chidwi amatha kufikira 70mm. Masensa ochititsa chidwi amabwera m'mitundu yosiyanasiyana yoyika: Masensa a Flush amathamangitsidwa ndi malo oyikapo, pomwe masensa osasunthika amatuluka mamilimita angapo, kukwaniritsa mtunda waukulu wosinthira.

Mtunda wodziwikiratu wa masensa ochititsa chidwi umakhudzidwa ndi coefficient yokonza, ndipo mtunda wosinthira zitsulo zina osati zitsulo ndizochepa. LANBAO imatha kupereka masensa osasunthika omwe ali ndi chowongolera cha 1, chomwe chimakhala ndi mtunda wosinthira yunifolomu pazitsulo zonse. Masensa ochititsa chidwi nthawi zambiri amagwiritsidwa ntchito ngati PNP/NPN nthawi zambiri amatsegula kapena otseka. Mitundu yokhala ndi zotsatira za analogi imatha kukwaniritsa zofunikira zapadera.

Yolimba komanso yodalirika - Mulingo wapamwamba wachitetezo woyenera malo ovuta

Pokhala ndi kutentha kwakukulu kogwiritsira ntchito komanso chitetezo chapamwamba, masensa awa ndi abwino kwambiri kuti agwiritsidwe ntchito m'madera ovuta a mafakitale. Mwa iwo, masensa ochititsa chidwi okhala ndi mulingo wachitetezo wa IP68 amakhala ndi ntchito yosindikiza kwambiri m'mafakitale monga chakudya, mankhwala, ndi makina omanga. Kutentha kwawo kumatha kufika 85 ° C nthawi zambiri.

Cholumikizira cha M12 chimatsimikizira kukhazikitsa kosavuta

Cholumikizira cha M12 ndiye mawonekedwe olumikizirana ma sensor chifukwa amatha kutsimikizira kuyika mwachangu, kosavuta komanso kolondola. LANBAO imaperekanso masensa ochititsa chidwi okhala ndi ma chingwe, omwe nthawi zambiri amaikidwa m'mapulogalamu okhala ndi malo ochepa. Chifukwa chakugwiritsa ntchito kwake komanso kudalirika kwakukulu, masensa ochititsa chidwi ndi ofunika kwambiri paukadaulo wamakono wama automation ndipo amagwiritsidwa ntchito m'mafakitale ambiri.
