Pressure sensor 296-8060 yeCaterpillar excavator chikamu

Thermoelectric sensor

1. Thermoelectric effect

Kana maviri maconductors esimbi A uye B ane zvimiro zvakasiyana akabatana mune yakavharwa loop, kana tembiricha yekusangana isina kuenzana (T0≠T), simba remagetsi rinogadzirwa pakati pemakondakita maviri, uye imwe huwandu hwazvino huchavapo mukati. loop. Ichi chiitiko chinonzi thermoelectric effect.

2. Thermal resistance sensor

Zvigadzirwa zvekupisa zvinopisa zvinowanzo simbi dzakachena, uye platinamu, mhangura, nickel, iron uye zvichingodaro zvinoshandiswa zvakanyanya.

3. Thermistor sensor

Thermistors inogadzirwa semiconductors uye ine zvinotevera hunhu kana zvichienzaniswa nesimbi thermistors:

1) yakakura tembiricha coefficient yekupikisa uye yakanyanya kunzwisiswa;

2) chimiro chakareruka, vhoriyamu diki uye chiyero chakareruka;

3) High resistivity uye yakakodzera kuyerwa kwakasimba;

4) Ukama huri pakati pekupikisa uye kushanduka kwekushisa hakuna mutsara;

5) kugadzikana kusina kunaka.

Kune matatu anonyanya kushandiswa:

1. Zvinoenderana nehuwandu hwemuviri wema sensors, anogona kukamurwa kuita masensa akadai sekufamba, simba, kumhanya, tembiricha, kuyerera uye gasi kuumbwa.

Zvinoenderana neanoshanda musimboti we sensors, anogona kukamurwa kuita kuramba, capacitance, inductance, voltage, Hall, photoelectric, grating, thermocouple uye mamwe ma sensor.

2. Zvinoenderana nechimiro chechiratidzo chekubuda che sensor, inogona kukamurwa kuita: chinja-mhando sensors ayo anobuda ari kuchinja maitiro ("1" uye "0" kana "pa" uye "kudzima"); Iyo yakabuda ndeye analog sensor; Digital sensor iyo inobuda ndeye pulse kana kodhi.

3.Sensors inoshandiswa kuyera kutonhora uye kudzvinyirira kwemvura yakasiyana-siyana (yakadai sekushisa kwekutora, mhepo yemhepo, kutonhora kwemvura inotonhora uye kushandiswa kwejekiseni yemafuta, nezvimwewo); Kune masensa anoshandiswa kuona kumhanya uye chinzvimbo chechikamu chimwe nechimwe (senge kumhanya kwemotokari, throttle kuvhura, camshaft, crankshaft, kona uye kumhanya kwekutapurirana, chinzvimbo cheEGR, nezvimwewo); Kune zvakare ma sensors ekuyera injini mutoro, kugogodza, misfire uye okisijeni zvirimo mumhepo yekubuda; Sensor yekuona nzvimbo yechigaro; Sensors yekuyera kumhanya kwevhiri, kureba kwemugwagwa mutsauko uye kudzvanywa kwetai mu-anti-lock braking system uye kumisa kudzora mudziyo; Kuti udzivirire airbag yemutyairi wepamberi, kwete chete mamwe ma sensors ekudhumhana uye acceleration sensors anodiwa. Yakatarisana nevhoriyamu yedivi remugadziri, bhegi repamusoro remhepo uye mamwe anoyevedza mativi emusoro airbag, masensa anofanira kuwedzerwa. Sezvo vatsvakurudzi vachishandisa anti-collision sensors (radar kana mamwe ma sensors) kutonga uye kudzora kukwidziridzwa kwemotokari, iko kukurumidza kwevhiri rimwe nerimwe uye torque inodiwa, iyo braking system yave chikamu chakakosha chekudzora kugadzikana kwemotokari. system.
