Inoshanda kune CAT excavator zvikamu Pressure Sensor 276-6793

1. Pressure sensor mukuyera system

Mune otomatiki kudzora kwekuyera maitiro, iyo yekumanikidza sensor inodiwa kuti unyatso kunzwa chiratidzo chegiravhiti. Uye ine zvirinani kushandura mhinduro uye zvirinani anti-kupindira kuita. Chiratidzo chinopiwa ne sensor pressure inogona kuratidzwa zvakananga, kurekodhwa, kudhindwa, kuchengetwa kana kushandiswa kwekugadzirisa mhinduro yehurongwa hwekutsvaga. Iko kubatanidzwa kwekumanikidza sensor uye kuyera dunhu kunoderedza zvakanyanya saizi yese yemidziyo. Uye zvakare, kuvandudza tekinoroji yekudzivirira zvakare inovandudza iyo anti-kupindira kugona uye otomatiki kudzora dhigirii rekuyera kudzvanywa sensor.

2. Kudzvinyirira sensors mu petrochemical industry

Pressure sensor ndeimwe yeanonyanya kushandiswa ekuyeresa michina mu petrochemical otomatiki control. Mumapurojekiti makuru emakemikari, anenge ese mashandisirwo emagetsi sensors akafukidzwa: kusiyanisa kudzvanywa, kumanikidzwa kwakazara, geji kudzvanywa, kukwira kwepamusoro, kusiyanisa kudzvanywa, tembiricha yakakwira, tembiricha yakadzika, kure kure flange kumanikidza ma sensors emhando dzakasiyana siyana uye yakakosha kugadzirisa.

Iko kudiwa kwema sensors ekumanikidza muindasitiri ye petrochemical inonyanya kutarisisa pazvinhu zvitatu: kuvimbika, kugadzikana uye kunyatsojeka. Pakati pavo, kuvimbika uye zvimwe zvakawanda zvinodiwa, senge reshiyo yedaro uye rudzi rwebhazi, zvinoenderana nedhizaini yedhizaini, dhizaini yekugadzira tekinoroji uye zvimiro zvechitunha. Iko kugadzikana uye kurongeka kwakanyanya kwekumanikidza transmitter kunonyanya kuvimbiswa nekugadzikana uye kuyerwa kwechiyero chepressure sensor.

Iko kuyerwa kwechiyero uye kumhanya kwekupindura kweiyo pressure sensor inoenderana nechiyero chechiyero cheiyo pressure transmitter. Iyo tembiricha uye static kumanikidza maitiro uye kugadzikana kwenguva refu kweiyo pressure sensor inoenderana nekugadzikana kweiyo pressure transmitter. Iko kudiwa kwema sensors ekumanikidza mu petrochemical indasitiri inoratidzwa mune ina maficha: kuyerwa kwechiyero, kukurumidza kupindura, tembiricha maitiro uye static kumanikidza maitiro, uye kugadzikana kwenguva refu.

3. Pressure sensor mukurapa kwemvura

Indasitiri yekuchengetedza nharaunda yekuchenesa mvura yakasimukira nekukurumidza mumakore achangopfuura uye ine tarisiro yakakura. Mumvura uye kurapwa kwemvura yakasviba, ma sensors ekumanikidza anopa kudzora kwakakosha uye kutarisa kwekuchengetedza system uye kuvimbiswa kwemhando. Iyo yekumanikidza sensor inoshandura kudzvanywa (kazhinji kudzvanywa kwemvura kana gasi) kuita chiratidzo chemagetsi chekubuda. Simba remagetsi masaini anogona zvakare kushandiswa kuyera chiyero chemvura ye static fluid, saka inogona kushandiswa kuyera chiyero chemvura. Iyo inonzwa chinhu chepressure sensor inonyanya kuumbwa nesilicon mukombe inonzwa chinhu, silicone mafuta, isolation diaphragm uye air duct. Dzvinyiriro yesvikiro yakayerwa inoendeswa kudivi resilicon kapu element kuburikidza neiyo yekuzviparadzanisa diaphragm uye silicone mafuta. The atmospheric reference pressure inoshanda kune rumwe rutivi rwesilicon cup element kuburikidza nemhepo duct. Silicon mukombe kapu-yakaita monocrystalline silicon wafer ine pasi yakatetepa. Pasi pechiito chekumanikidza, diaphragm iri pazasi pekapu yakashongedzwa zvine elastically nekushomeka kwekutamisa. Monocrystalline silicon yakanakira elastomer. Iyo deformation yakanyatso kuenzana nekudzvanywa, uye kudzoreredza kuita kwakanaka.

4. Pressure sensors muindasitiri yezvokurapa

Nekuvandudzwa kwemusika wemidziyo yekurapa, zvinodiwa zvepamusoro zvinoiswa pamberi pekushandiswa kwema sensors muindasitiri yezvokurapa, sekurongeka, kuvimbika, kugadzikana uye huwandu. Pressure sensor ine yakanaka application mune zvishoma invasive catheter ablation uye tembiricha sensor kuyerwa.

5.MEMS pressure sensor

MEMS pressure sensor imhando yefirimu yakaonda, inozokanganisa kana yaiswa pasi pekumanikidzwa. Majeji eStrain (piezoresistive sensing) anogona kushandiswa kuyera deformation iyi, uye capacitive sensing inogona kushandiswa kuyera shanduko yedaro pakati penzvimbo mbiri.
