Pressure switch 97137042 ndiyoyenera sensor ya Isuzu

1. Kulondola

Kulondola ndi ndondomeko yofunikira ya sensa, yomwe ndi ulalo wofunikira wokhudzana ndi kuyeza kulondola kwa dongosolo lonse la kuyeza. Kukwera kulondola kwa sensa, kumakhala kokwera mtengo kwambiri. Choncho, kulondola kwa sensa kumangofunika kukwaniritsa zofunikira za dongosolo lonse la kuyeza, ndipo sikoyenera kusankha kwambiri. Mwanjira iyi, tikhoza kusankha sensa yotsika mtengo komanso yosavuta pakati pa masensa ambiri omwe amakwaniritsa cholinga chofanana.

Ngati cholinga cha kuyeza ndi kusanthula kwabwino, masensa omwe ali ndi kubwerezabwereza kubwereza ayenera kusankhidwa, koma omwe ali ndi mtengo wokwanira wamtengo wapatali sayenera kusankhidwa; Ngati ndi kusanthula kachulukidwe, ndikofunikira kupeza miyeso yolondola, chifukwa chake ndikofunikira kusankha masensa okhala ndi milingo yolondola yolondola.

Pazinthu zina zapadera, ngati sizingatheke kusankha sensa yoyenera, tiyenera kupanga ndi kupanga sensa tokha. Kuchita kwa sensa yodzipangira yokha iyenera kukwaniritsa zofunikira zogwiritsira ntchito.

2.Mtundu

Pali mitundu yambiri yamasensa amakina, monga resistance strain gauge pressure sensor, semiconductor strain gauge pressure sensor, piezoresistive pressure sensor, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor and capacitive acceleration sensor. Koma chogwiritsidwa ntchito kwambiri ndi piezoresistive pressure sensor, yomwe ili ndi mtengo wotsika kwambiri, yolondola kwambiri komanso mikhalidwe yabwino yofananira.

3. Dziwani

Tikachepetsa mphamvu ya sensor yamphamvu, timadziwa kaye kayezedwe kake ka resistive strain. Resistance strain gauge ndi mtundu wa chipangizo chodziwika bwino chomwe chimasintha kupsinjika kwa gawo loyezedwa kukhala chizindikiro chamagetsi. Ndi chimodzi mwa zigawo zikuluzikulu za piezoresistive mavuto sensa. Mageji a Metal resistance ndi ma semiconductor strain gauges amagwiritsidwa ntchito kwambiri. Pali mitundu iwiri yazitsulo zoyezera kukana zitsulo: zoyezera za waya ndi zoyezera zachitsulo. Nthawi zambiri, strain gauge imamangirizidwa mwamphamvu ku gawo lapansi lomwe limatulutsa zovuta zamakina kudzera pa zomatira zapadera. Pamene kupsyinjika kwa gawo lapansi kumasintha, kukana kwa strain gauge kumasintha, kotero kuti voteji yomwe imagwiritsidwa ntchito pa resistor imasintha. Nthawi zambiri, mtundu woterewu wa strain gauge umakhala ndi kusintha pang'ono kukana kukanikizidwa. Nthawi zambiri, mtundu wamtunduwu wamtunduwu umapanga mlatho wovutitsa, womwe umakulitsidwa ndi amplifier wotsatira kenako ndikutumizidwa kudera lokonzekera (nthawi zambiri kutembenuka kwa A/D ndi CPU) kuti iwonetsedwe kapena kuphedwa.
