Kushandisa musimboti wepressure sensor

1. Kusiyana-siyana

Kune akawanda marudzi emamechanic sensors, senge resistance strain gauge pressure sensor, semiconductor strain gauge pressure sensor, piezoresistive pressure sensor, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor uye capacitive acceleration sensor. Asi iyo inonyanya kushandiswa ndeye piezoresistive pressure sensor, iyo ine mutengo wakaderera kwazvo, yakakwirira kurongeka uye zviri nani mutsara maitiro.

2. Kunzwisisa

Mune decompression resistance pressure sensor, isu tinotanga tanzwisisa kupikisa strain gauge chinhu ichi. The resistance strain gauge chinhu chinonzwisa tsitsi chinoshandura shanduko pachikamu chakayerwa kuita chiratidzo chemagetsi. Icho chimwe chezvikamu zvikuru zvepiezoresistive strain sensor. Iwo anonyanya kushandiswa ekupikisa strain geji isimbi inopikisa strain geji uye semiconductor strain geji. Kune marudzi maviri esimbi inopikisa strain geji: wire strain geji uye metal foil strain geji. Kazhinji, iyo strain geji inosungirirwa zvakasimba kune mechanical strain matrix neakakosha bonding agent. Kana kushushikana kwematrix kuchichinja, gauge yekupokana inokanganisa zvakare, kuitira kuti kukosha kwekupokana kweiyo strain gauge kushanduke, uye voltage inoshandiswa pakupikisa kuchinja. Iko kukosha kwekupokana kweiyi strain geji kazhinji idiki kana ichisimbiswa, uye iyi strain geji inowanzo umbwa neA strain bhiriji, uye inokwidziridzwa neinotevera chiridzwa amplifier, uye yobva yaendeswa kune yekugadziridza dunhu (kazhinji A / D kutendeuka uye CPU) kuratidza kana executive mechanism.
