Masensa ena amagalimoto omwe magalimoto anu ali nawo ndi ntchito zake

Masensa agalimoto ndi zida zolowera pamakompyuta apagalimoto.Amasamutsa zidziwitso zamakhalidwe osiyanasiyana ogwirira ntchito pamagalimoto monga kuthamanga kwagalimoto, kutentha kwama media osiyanasiyana, mawonekedwe a injini kukhala chizindikiro chamagetsi kuti atumize kumakompyuta kuti injiniyo ikhale yogwira ntchito bwino.

Magalimoto akamachulukirachulukira, thiransifoma ntchito zambiri mgalimoto zimayendetsedwa ndi makompyuta.Pali masensa ambiri pagalimoto imodzi, amatha kugawidwa kukhala sensa ya okosijeni, sensa ya mpweya, sensa yothamanga, sensa ya nitrogen oxide, sensor ya kutentha ndi sensor pressure malinga ndi ntchito yawo.Sensa imodzi ikalephera, chipangizo chofananira sichingagwire ntchito kapena kugwira ntchito molakwika.Kenako, tiyeni tiwuze masensa ena akulu ndi ntchito yake.

Sensa yoyenda

Sensa yothamanga imagwiritsidwa ntchito makamaka poyezera mpweya wa injini ndi kutuluka kwamafuta.Kuyeza kwa mpweya kumagwiritsidwa ntchito ndi injini yoyang'anira magetsi kuti adziwe momwe kuyaka, kuwongolera kutentha kwa mpweya, chiyambi, kuyatsa, etc. Pali mitundu inayi ya masensa oyenda mpweya: rotary vane (mtundu wa tsamba), carmen vortex mtundu. , mtundu wa waya wotentha ndi mtundu wa filimu yotentha.Mapangidwe a air flowmeter amtundu wa rotary vane ndi osavuta komanso kulondola kwake ndikotsika.Mpweya woyezedwa umafunika kulipidwa kutentha.Carmen vortex air flowmeter ilibe mbali zosunthika, zomwe zimawunikira komanso kulondola kwambiri.Pamafunikanso chipukuta misozi cha thermometer.

The otentha waya mpweya flowmeter ali mkulu muyeso molondola ndipo safuna kutentha chipukuta misozi, koma n'zosavuta kukhudzidwa ndi mpweya pulsation ndi kusweka waya.Mfundo yoyezera yotentha filimu mpweya flowmeter ndi yofanana ndi ya otentha waya mpweya flowmeter, koma voliyumu ndi yaing'ono, oyenera kupanga misa ndi mtengo wotsika.Tonse tikudziwa kuti pali ma charger a USB m'magalimoto ambiri, titha kulipira foni yathu ndi charger yam'manja yopanda zingwe.

Ntchito ya flow sensor

Liwiro la choyikapo ndilofanana ndi kutuluka, ndipo chiwerengero cha kusinthika kwa choyimitsa chimagwirizana ndi kutuluka kwathunthu.Kutulutsa kwa turbine flowmeter ndi chizindikiro chosinthika pafupipafupi, chomwe sichimangowonjezera kusokoneza kwa dera lodziwikiratu, komanso kumathandizira njira yodziwira otaya.Kuchuluka kwake kumatha kufika 10: 1 ndipo kulondola kwake kuli mkati mwa ± 0.2%.Nthawi yokhazikika ya turbine flowmeter yokhala ndi inertia yaying'ono ndi kukula yaying'ono imatha kufika masekondi 0.01.

Pressure sensor

The kuthamanga sensa makamaka ntchito kudziwa yamphamvu zoipa kuthamanga, mumlengalenga, kulimbikitsa chiŵerengero cha turbine injini, yamphamvu mkati kuthamanga, mafuta kuthamanga, etc. Suction negative pressure sensor makamaka ntchito kudziwa kuyamwa kuthamanga, zoipa kuthamanga ndi mafuta.Masensa amagetsi amagalimoto amagwiritsidwa ntchito kwambiri mu capacitive, piezoresistive, differential transformer (LVDT) ndi surface elastic wave (SAW).

Zochita za pressure sensor

Pressure sensor nthawi zambiri imakhala ndi zinthu zomwe zimakhudzidwa ndi kupanikizika komanso ma signature optical network unit.Malinga ndi mitundu yosiyanasiyana yoyezetsa, ma sensor amphamvu amatha kugawidwa kukhala sensor yamagetsi yamagetsi, sensor yosiyanitsa kuthamanga komanso sensor yothamanga kwambiri.Pressure sensor ndiye sensor yomwe imagwiritsidwa ntchito kwambiri pamachitidwe amakampani.Amagwiritsidwa ntchito m'madera osiyanasiyana amagetsi owongolera, kuphatikiza madzi ndi hydropower, zoyendera njanji, zomanga zanzeru, kupanga zowongolera zokha, zakuthambo, mafakitale ankhondo, petrochemical, chitsime chamafuta, mphamvu yamagetsi, zombo, chida cha makina, mapaipi ndi mafakitale ena ambiri.

Kugogoda sensor

Knock sensor imagwiritsidwa ntchito kuzindikira kugwedezeka kwa injini, kuwongolera ndikupewa kugogoda kwa injini posintha mbali yoyatsira.Kugogoda kumatha kudziwika pozindikira kuthamanga kwa silinda, kugwedezeka kwa injini ndi phokoso loyaka.Masensa akugogoda ndi magnetostrictive ndi piezoelectric.Kutentha kwautumiki wa magnetostrictive kugogoda sensa ndi - 40 ℃ ~ 125 ℃, ndipo mafupipafupi osiyanasiyana ndi 5 ~ 10kHz;Pakatikati pafupipafupi 5.417khz, kumva kwa piezoelectric kugogoda sensa kumatha kufika 200mV / g, ndipo kumakhala ndi mzere wabwino pamatalikidwe osiyanasiyana a 0.1g ~ 10g.

Ntchito ya knock sensor

Amagwiritsidwa ntchito kuyeza jitter ya injini ndikusintha momwe amayatsira pasadakhale pomwe injini imatulutsa kugogoda.Kawirikawiri, iwo ndi piezoelectric ceramics.Injini ikagwedezeka, zoumba mkati zimafinyidwa kuti zipange chizindikiro chamagetsi.Chifukwa chizindikiro chamagetsi ndi chofooka kwambiri, chingwe cholumikizira cha masensa ogogoda ambiri chimakutidwa ndi waya wotetezedwa.

Powombetsa mkota

Magalimoto amasiku ano amagwiritsa ntchito zida zambiri zowonera, ndipo sensa iliyonse imakhala ndi cholinga chothandiza.Galimoto yamtsogolo ikhoza kukhala ndi masensa mazana angapo otumiza uthenga ku ma ECU amphamvu ndikupangitsa magalimoto kukhala oyendetsa bwino komanso otetezeka kuyendetsa.Masensa athu ndi apadera amitundu yosiyanasiyana yamagalimoto, monga momwe tililiVW Oxygen Sensor.Zomverera ndizofunikira kwambiri pagalimoto.Kuti mumve zambiri za masensa odziwikiratu, pls pitani ku YASEN.
