Mfundo yogwiritsira ntchito pressure sensor

1. Zosiyanasiyana

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, wolondola kwambiri komanso makhalidwe abwino a mzere.

2. Kumvetsetsa

Mu decompression resistance resistance sensor, timamvetsetsa kaye kaye kayezedwe kazinthu kameneka. The resistance strain gauge ndi chipangizo chodziwikiratu chomwe chimasintha kusintha kwa zovuta pagawo loyezedwa kukhala chizindikiro chamagetsi. Ndi chimodzi mwa zigawo zikuluzikulu za piezoresistive mavuto sensa. Zoyezera zomwe zimagwiritsidwa ntchito kwambiri ndi zoyezera zachitsulo zosakanizidwa ndi zida za semiconductor strain gauges. Pali mitundu iwiri yoyezera kupsinjika kwachitsulo: choyezera cha waya ndi choyezera chachitsulo chachitsulo. Kawirikawiri, strain gauge imamangirizidwa mwamphamvu ku matrix strain matrix ndi wothandizira wapadera. Kupsyinjika kwa matrix kukasintha, kukana kwa strain gauge kumasokonekera, kotero kuti mtengo wotsutsa wa strain gauge umasintha, ndipo voteji yomwe imagwiritsidwa ntchito pakukana imasintha. Mtengo wotsutsa wa geji yamtunduwu nthawi zambiri imakhala yaying'ono ikatsindikiridwa, ndipo geji yamtunduwu nthawi zambiri imakhala ndi mlatho wa A strain, ndipo imakulitsidwa ndi amplifier yotsatizana, kenako imatumizidwa kudera lokonzekera (nthawi zambiri kutembenuka kwa A/D ndi CPU) chiwonetsero kapena njira yoyendetsera.
