Kuyika Sensola Yosiya Kutentha kwa Mpweya

• Sensa ya Leaving Air Temperature (LAT) iyenera kukhala pamalo otulutsa bokosi la PREHEAT-X.
• Pezani sensa pakati pa gawo lalikulu kwambiri la khoma la bokosi la PREHEAT-X. Gwiritsani ntchito template yomwe yaperekedwa ndi kubowola kwa inchi 5/16 kuti mupange dzenje la sensor.
• Ikani gasket pamwamba pa kafukufukuyo ndikukwera motetezeka ku khoma la bokosi pogwiritsa ntchito zomangira zachitsulo zomwe zaperekedwa. Onetsetsani kuti gasket imapanikizidwa kuti ikhale yotsekera mpweya.

Kuti muwone bwino, ikani zotsekera kunja kwa khoma la bokosi, pamwamba pa sensa. Izi zidzathandiza kuteteza ma gradients kuti asakhudze sensor.

CHENJEZO:
Onetsetsani kuti Sensor (s) yanu Yosiya Kutentha kwa Mpweya imakwezedwa ndi waya molingana ndi malangizowa musanayambe kuyesa chipangizocho kapena valavu yosinthira siingathe kulamulira bwino ndipo ingawononge zipangizo zanu.

ZOWONJEZERA A: LAT SENSOR

Kusiya Sensor ya Kutentha kwa Air

• Ngati mukukayikira kuti chojambulira cha Entering or Leaving Air Temperature sichikuwerenga bwino, onetsetsani kuti zolumikizira mawaya zili zolimba komanso kuti mawaya onse alumikizidwa bwino. Mutha kuyang'ana magwiridwe antchito a Leaving Air Temperature sensor poyesa kukana kapena voltagndi kugwiritsa ntchito digito multimeter. Khazikitsani mita ku DC Volts. Ikani kafukufuku wabwino pa terminal ya AI ndi kafukufuku woyipa pa terminal ya GND. Werengani DC Volts ndikupeza kuti voltage mu Gulu 5, tsamba ili.
• Werengani kutentha kofanana ndi voltage and determine if this is close to the actual temperature the sensor is exposed to. If the temperature from the chart is different by more than a few degrees, you probably have a defective or damaged sensor.
• You can also check the sensor resistance to determine correct operation.

Malangizo Oyesera a Thermistor Sensor

• Kuti muwerenge kukana, ikani mita kukhala ohms. Chotsani cholumikizira cha sensa kuchokera pa bolodi ndikuyesa kukana pa mawaya osalumikizidwa. Kukaniza uku kuyenera kufanana ndi kutentha komwe kumachokera pa Table 5, tsamba ili.

Malangizo Oyesera a Thermistor Sensor

1. Gwiritsani ntchito gawo lotsutsa kuti muwone sensor ya thermistor pomwe imalumikizidwa ndi owongolera (osayendetsedwa).
2. Gwiritsani ntchito voltage column kuti muyang'ane masensa pomwe olumikizidwa ndi owongolera oyendetsedwa ndi magetsi. Werengani voltage yokhala ndi mita yoyikidwa pa ma volt a DC. Ikani chiwongolero cha "-" (minus) pa terminal ya GND ndi "+" (kuphatikiza) chotsogolera pa cholumikizira cha sensor chomwe chikufufuzidwa.
