Kuthamanga kwamafuta sensa ya Dodge Cummins yopuma injini yamafuta 4921505

Njira yolumikizira sensor

Ma waya a masensa nthawi zonse akhala amodzi mwa mafunso omwe amafunsidwa pafupipafupi pakugula kwa makasitomala. Makasitomala ambiri sadziwa kuyatsa masensa. M'malo mwake, njira zama waya za masensa osiyanasiyana ndizofanana. Masensa opanikizika nthawi zambiri amakhala ndi mawaya awiri, mawaya atatu, mawaya anayi ndi mawaya ena asanu.

Dongosolo lamawaya awiri a sensor pressure ndi losavuta, ndipo makasitomala ambiri amadziwa kulumikiza mawaya. Waya wina amalumikizidwa ndi mtengo wabwino wamagetsi, ndipo waya wina, ndiye kuti, waya wolumikizira, umalumikizidwa ndi mzati woyipa wamagetsi kudzera pazida, zomwe ndizosavuta. Dongosolo la waya wamagetsi atatu amagetsi amatengera ma waya awiri, ndipo wayawo amalumikizidwa mwachindunji ndi mtengo woyipa wamagetsi, womwe ndi wovuta kwambiri kuposa ma waya awiri. Sensa yamagetsi yamagetsi anayi iyenera kukhala yolowera mphamvu ziwiri, ndipo zina ziwiri ndizotulutsa ma siginecha. Ambiri mwa mawaya anayi amatulutsa mphamvu m'malo mwa 4 ~ 20mA, ndipo 4 ~ 20mA imatchedwa pressure transmitter, ndipo ambiri amapangidwa kukhala mawaya awiri. Zina mwazomwe zimatuluka pamasensa opanikizika sizimakulitsidwa, ndipo kutulutsa kwathunthu kumangokhala mamilivolti makumi khumi, pomwe masensa ena opanikizika amakhala ndi mabwalo okulitsa mkati, ndipo kutulutsa kwathunthu ndi 0 ~ 2V. Ponena za momwe mungalumikizire chida chowonetsera, zimadalira mtundu wa kuyeza kwa chidacho. Ngati pali giya yoyenera kutulutsa chizindikiro, imatha kuyeza mwachindunji, apo ayi, gawo losinthira ma siginecha liyenera kuwonjezeredwa. Pali kusiyana pang'ono pakati pa sensa yamawaya asanu ndi sensa yama waya anayi, ndipo pali ma sensor ochepera asanu pamsika.

Pressure sensor ndi imodzi mwama sensor omwe amagwiritsidwa ntchito kwambiri. Traditional kuthamanga masensa makamaka mawotchi zipangizo, amene amasonyeza kupanikizika ndi mapindikidwe zotanuka zinthu, koma dongosolo lalikulu mu kukula ndi kulemera kulemera, ndipo sangathe kupereka linanena bungwe magetsi. Ndi chitukuko chaukadaulo wa semiconductor, masensa amphamvu a semiconductor adayamba kukhalapo. Amadziwika ndi voliyumu yaying'ono, kulemera kopepuka, kulondola kwambiri komanso mawonekedwe abwino a kutentha. Makamaka pakukula kwaukadaulo wa MEMS, masensa a semiconductor akukula kupita ku miniaturization ndi kugwiritsa ntchito mphamvu zochepa komanso kudalirika kwambiri.
