Ifanelekile kwiFutian Cummins IFS3.8 inzwa yoxinzelelo lweoyile4928594

1. Loluphi uhlobo lwesixhobo soxinzelelo?

Ulwelo lweViscous kunye nodaka luya kuvala ujongano loxinzelelo.Ngaba i-solvents okanye i-corrosive substances izonakalisa izinto ezikwi-sensor ye-pressure sensor ehambelana ngqo nale midiya?Ezi zinto ziya kugqiba ukuba ngaba ukhetha ifilimu yokwahlula ngokuthe ngqo kunye nezinto eziphathekayo ngokuqhagamshelana ngqo nophakathi.

2. Luluphi uhlobo loxinzelelo olufanele ukulinganisa inzwa yoxinzelelo?

Okokuqala, misela ixabiso elikhulu loxinzelelo olulinganisiweyo kwinkqubo.Ngokuqhelekileyo, kuyimfuneko ukukhetha i-transmitter enoluhlu loxinzelelo malunga namaxesha angama-1.5 amakhulu kunexabiso elikhulu.Oku kungenxa yokuba kwiinkqubo ezininzi, ngakumbi kumlinganiselo woxinzelelo lwamanzi kunye nokucutshungulwa, kukho iincopho kunye nokuguquguquka okuqhubekayo okungahambi kakuhle, kwaye le ncopho yangoko inokutshabalalisa inzwa yoxinzelelo.Ixabiso eliphezulu loxinzelelo oluphezulu okanye ukugqithisa kancinane ixabiso elilinganisiweyo lomthumeli liya kunciphisa ubomi benzwa, eya kunciphisa ukuchaneka.Ke isithinteli sinokusetyenziselwa ukunciphisa uxinzelelo lwe-burr, kodwa oku kuyakucothisa isantya sokuphendula senzwa.Ngoko ke, uluhlu loxinzelelo, ukuchaneka kunye nokuzinza kufuneka kuqwalaselwe ngokupheleleyo xa ukhetha umthumeli.

3. Ichaneke kangakanani inzwa yoxinzelelo?

Ukuchaneka kunqunywe ngokungafaniyo, i-hysteresis, i-non-repeatability, iqondo lokushisa, i-zero offset scale kunye neqondo lokushisa.Kodwa ngokuyintloko ngenxa yokungahambelani, i-hysteresis kunye nokungaphindaphindi.Ukuphakama kokuchaneka, ixabiso eliphezulu.

4. Loluphi uhlobo lwesignali yemveliso oyifunayo?

Imveliso yedijithali ye-mV, i-V, i-mA kunye ne-frequency ixhomekeke kwizinto ezininzi, kubandakanywa umgama phakathi kwe-transmitter kunye nomlawuli wenkqubo okanye umboniso, nokuba kukho "ingxolo" okanye ezinye iimpawu zokuphazamiseka kwe-elektroniki, nokuba i-amplifier iyafuneka, kunye nendawo. yeamplifier.Kwizixhobo ezininzi ze-OEM ezinomgama omfutshane phakathi komthumeli kunye nomlawuli, sisisombululo esinoqoqosho nesisebenzayo ukwamkela isidluliseli semveliso ye-mA.

Ukuba kuyimfuneko ukukhulisa umqondiso wokuphuma, i-transmitter ene-amplification eyakhelwe-ngaphakathi ingasetyenziswa.Imveliso yezinga le-MA okanye i-frequency output ingasetyenziselwa ukuhanjiswa komgama omde okanye izibonakaliso ezinamandla zokuphazamiseka kwe-elektroniki.

Ukuba kwindawo ene-RFI ephezulu okanye i-EMI index, ukhuseleko olukhethekileyo okanye isihluzo kufuneka siqwalaselwe ngaphandle kokukhetha i-mA okanye i-frequency output.
