Siab sensor 296-8060 rau Caterpillar excavator ib feem

Thermoelectric sensor

1. Cov nyhuv thermal

Thaum ob lub hlau conductors A thiab B nrog cov khoom sib txawv txuas rau hauv lub voj kaw, yog tias qhov sib txuas qhov kub tsis sib npaug (T0≠T), lub zog hluav taws xob yuav raug tsim los ntawm ob lub conductors, thiab qee qhov tam sim no yuav muaj nyob hauv lub voj. Qhov tshwm sim no hu ua thermoelectric effect.

2. Thermal resistance sensor

Cov ntaub ntawv thermal kuj feem ntau yog cov hlau ntshiab, thiab platinum, tooj liab, npib tsib xee, hlau thiab lwm yam yog siv dav.

3. Thermistor sensor

Thermistor yog ua los ntawm semiconductors thiab muaj cov yam ntxwv hauv qab no piv nrog cov thermistor hlau:

1) loj kub coefficient ntawm kuj thiab siab rhiab heev;

2) Cov qauv yooj yim, ntim me me thiab ntsuas qhov taw tes yooj yim;

3) High resistivity thiab haum rau dynamic ntsuas;

4) Kev sib raug zoo ntawm kev tiv thaiv thiab kev hloov pauv kub yog nonlinear;

5) tsis zoo stability.

5 muab faib kho

Muaj peb feem ntau siv:

1. Raws li lub cev muaj nuj nqis ntawm cov sensors, lawv tuaj yeem muab faib ua cov sensors xws li hloov chaw, quab yuam, ceev, kub, ntws thiab roj muaj pes tsawg leeg.

Raws li lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov sensors, lawv tuaj yeem muab faib ua qhov tsis kam, capacitance, inductance, voltage, Hall, photoelectric, grating, thermocouple thiab lwm yam sensors.

2. Raws li qhov tshwm sim ntawm cov teeb liab tawm ntawm lub sensor, nws tuaj yeem muab faib ua: hloov hom sensors uas nws cov zis hloov pauv qhov tseem ceeb ("1" thiab "0" lossis "on" thiab "tawm"); Cov zis yog ib qho analog sensor; Digital sensor uas nws cov zis yog mem tes lossis code.

3.Sensors yog siv los ntsuas qhov kub thiab siab ntawm cov kua dej ntau yam (xws li qhov kub thiab txias, cua txias, dej txias thiab roj txhaj tshuaj, thiab lwm yam); Muaj cov sensors siv los txiav txim siab qhov ceev thiab txoj hauj lwm ntawm txhua qhov chaw (xws li lub tsheb ceev, lub qhov rooj qhib, camshaft, crankshaft, lub kaum ntse ntse thiab kev sib kis ceev, txoj hauj lwm ntawm EGR, thiab lwm yam); Kuj tseem muaj cov sensors rau ntsuas lub cav load, khob, misfire thiab oxygen cov ntsiab lus hauv cov pa tso pa; Ib lub sensor rau kev txiav txim qhov chaw ntawm lub rooj zaum; Sensors rau ntsuas lub log ceev, txoj kev qhov siab qhov sib txawv thiab lub log tsheb siab hauv kev tiv thaiv kev xauv lub kaw lus thiab cov cuab yeej tswj kev ncua; Txhawm rau tiv thaiv lub airbag ntawm tus neeg caij tsheb pem hauv ntej, tsis yog tsuas yog xav tau ntau qhov kev sib tsoo sensors thiab acceleration sensors. Tig lub khw muag khoom sab ntim, nyiaj siv ua haujlwm airbag thiab ntau lub ntsej muag sab taub hau airbag, sensors yuav tsum tau ntxiv. Raws li cov kws tshawb fawb siv cov tshuaj tiv thaiv kev sib tsoo (xws li radar lossis lwm yam sensors) los txiav txim thiab tswj lub tsheb nrawm nrawm ntawm lub tsheb, qhov nrawm nrawm ntawm txhua lub log thiab qhov xav tau torque, lub braking system tau dhau los ua ib feem tseem ceeb ntawm kev tswj lub tsheb. qhov system.
