Umgaqo osebenzayo we-excavator pressure sensor kunye nokutshintsha uxinzelelo

I-Excavator Pressure Sensor

Inzwa yoxinzelelo lweKomatsu iboniswe kuMfanekiso 4-20.Xa ioli ingena kwi-inlet yoxinzelelo kunye noxinzelelo lusetyenziswa kwi-diaphragm ye-oil pressure detector, i-diaphragm igoba kunye ne-deforms.Umaleko wokulinganisa uxhonywe kwelinye icala le-diaphragm, kwaye ixabiso lokuchasana lomgangatho womlinganiso liyatshintsha, litshintsha i-curvature ye-diaphragm ibe yi-voltage ephumayo, ethi idluliselwe kwi-amplifier yombane, eyandisa ngakumbi i-voltage. emva koko idluliselwe kwisilawuli se-electro-mechanical (ibhodi yekhompyutha).

Ukuphakama koxinzelelo kwi-sensor, iphezulu i-voltage ephumayo;ngokoxinzelelo lokuziva, inzwa yoxinzelelo idla ngokwahlulahlulwe ibe ziindidi ezimbini: inzwa yoxinzelelo oluphezulu kunye noxinzelelo oluphantsi.Inzwa yoxinzelelo oluphezulu isetyenziselwa ukulinganisa uxinzelelo lwemveliso kunye noxinzelelo lomthwalo wempompo ephambili.Izinzwa zoxinzelelo oluphantsi zisetyenziswa kwiinkqubo zokulawula ulingo kunye neenkqubo zokubuyiswa kweoli.

Umbane osebenzayo oqhelekileyo we-sensor zoxinzelelo yi-5V, i-9V, i-24V, njl. (ingqalelo ekhethekileyo kufuneka ihlawulwe ukuhlula xa kutshintshwa).Ngokubanzi, izinzwa zoxinzelelo kumatshini ofanayo zisebenza kumbane ofanayo.Ukusebenza kwangoku kwenzwa yoxinzelelo kuncinci kakhulu, kwaye inikwe amandla ngokuthe ngqo yibhodi yekhompyutheni.

Ukutshintshwa koxinzelelo kuboniswe kuMzobo 4-21.Umtshini woxinzelelo ufumanisa imeko yoxinzelelo (on / off) yesiphaluka somqhubi kwaye uyithumele kwibhodi yekhompyutheni.Kukho iintlobo ezimbini zokutshintsha koxinzelelo: ngokuqhelekileyo-uvuliwe kwaye uvaliwe, kuxhomekeke ekubeni isiphaluka sixhunyiwe xa kungekho xinzelelo kwi-port.Iimodeli ezahlukeneyo kunye neengxenye ezahlukeneyo zokutshintsha koxinzelelo zineengcinezelo ezahlukeneyo zokusebenzisa kunye nokusetha kwakhona uxinzelelo.Ngokuqhelekileyo, ukutshintshwa koxinzelelo kwi-rotary kunye nezixhobo zokusebenza zinoxinzelelo oluphantsi lwe-actuation, ngelixa ukutshintshwa koxinzelelo lokuhamba kunoxinzelelo oluphezulu lwe-actuation.
