Pressure sensor 17216318 ndiyoyenera VOLVO roller / grader

Posankha sensa yoyenera, mitundu yosiyanasiyana yamakina ndi owongolera omwe angakonzedwe ayenera kuyang'anitsitsa tsatanetsatane.Pafupifupi makina onse amakono omwe amafunika kukonzedwa kapena kukonzedwanso ali ndi zofunikira zenizeni za mitundu ya deta yomwe iyenera kutengedwa.Osati makina okha omwe ali ndi zofunikira zenizeni, komanso CPU ndi gawo la machitidwe olamulira ali ndi zofuna zawo.

Chifukwa cha kusiyana kumeneku, pali mitundu yosiyanasiyana ya masensa omwe alipo, ndipo sensa iliyonse imapangidwira ntchito yapadera kwambiri ndipo imapereka ndondomeko yeniyeni yeniyeni.Mu pepala ili, njira yosankha sensa yoyenera ya ntchito zosiyanasiyana idzaphunziridwa mosamala.Makamaka, chidziwitso choyambirira chogwiritsa ntchito magawo amakina kuti mudziwe mtundu wa sensa yomwe ingasankhidwe, momwe mungadziwire polarity yofunikira, komanso momwe mungasankhire pakati pa mayiko omwe nthawi zambiri amatseguka komanso otsekedwa.

Mitundu yosiyanasiyana yamagulu a sensa

Ubale pakati pa chinthu chomwe mukuyesera kuchizindikira ndi kusankha kwa sensor ndikofunikira kwambiri kuposa china chilichonse.Nthawi zambiri, ngati muwona kuti mwasankha molakwika pazinthu izi, mutha kupeza njira yopangira pulogalamu kapena gawo kuti musinthe polarity ya chizindikiro.

Komabe, ngati gulu lolakwika la sensa lisankhidwa, mankhwalawo sangawonekere konse.Palibe kuchuluka kwa mabwalo komwe kungathetse vutoli.

Sensor polarity

Zolowetsa zambiri za digito zimafunikira kulumikizidwa ndi magetsi a DC, nthawi zambiri 10 mpaka 24 vDC.Komabe, machitidwe ena amatha kugwiritsa ntchito 120 vAC kapena nthawi zina 24 vAC control voltage.Izi ndizopindulitsa muzochitika zina zapadera, chifukwa sizifuna zovuta za magetsi a DC ndipo zimangofunika thiransifoma.

Masensa a AC awa nthawi zambiri samayikidwa ndi polarity, ndipo mapepala a deta nthawi zambiri amasonyeza kuti katundu akhoza kuikidwa pa mawaya otentha kapena mawaya osalowerera ndale, omwe nthawi zambiri amakhala a bulauni ndi a buluu kuchokera ku zingwe zamchira zomwe zimayikidwa kale.

Sensa ya AC iyenera kusankhidwa pokhapokha gawo lothandizira la wolamulira likukonzedwa ngati AC.Izi sizodziwika ngati DC, koma mtundu uwu uyenera kugwiritsidwa ntchito ngati gawoli lapangidwira 120 vAC kulowetsa.

Nthawi zambiri amatsegula kapena amatsekedwa

Kusiyana kwina pazosankha za sensor ndikusankha pakati pa zotseguka (NO) ndi zotsekedwa (NC).Mkati mwa kuchuluka kwa makina owongolera digito, sizimapanga kusiyana konse, bola pulogalamuyo ilembedwera sensa yoyenera.

Kusiyana kokha kwa NO / NC ndiko kuti ngati mtundu wa sensa umasankhidwa kuti upangitse dera la sensa kuti litsegulidwe kuposa 50% ya moyo wake, likhoza kupulumutsa mphamvu.Kusungirako mtengo kungakhale kochepa, koma pamene mtengo woyambirira wa sensa ndi wofanana, ndizomveka kusankha zipangizo zogwirira ntchito bwino.
