Mercedes-Benz Ea Fa'a'ave'ave'ave'ave'ai 2038211592

Pressure sensor o le masini e sili ona masani ona faʻaaogaina i galuega tau alamanuia, lea e faʻaaogaina lautele i siosiomaga faʻatautaia otometi faʻapisinisi, e aofia ai le faʻasaoina o le vai ma le hydropower, nofoaafi felauaiga, fale atamamai, gaosiga otometi, aerospace, alamanuia militeri, petrochemical, suauʻu vaieli, eletise. malosiaga, va'a, masini meafaigaluega, paipa ma le tele o isi pisinisi. Ma i si'osi'omaga eseese, e mana'omia le fa'aogaina o ituaiga masini fa'amalosi e aloese ai mai mea sese.

Fa'atonuga galue o masini fa'amalosi eseese

1. Piezoresistive malosi sensor: Resistance gauge o se tasi o vaega autu o le piezoresistive strain sensor. O le mataupu faavae galue o le uʻamea teteʻe fua faʻatatau o le faʻalavelave faʻalavelave faʻapipiʻiina i luga o mea faʻavae e suia ma faʻaleagaina faʻainisinia, e masani ona taʻua o le aʻafiaga o le malosi.

2. Ceramic pressure sensor: E faʻavae le faʻaogaina o le sima i luga o le aafiaga piezoresistive, ma o le mamafa o loʻo galue saʻo i luga o le pito i luma o le diaphragm sima, e mafua ai le faʻaleagaina o le diaphragm. O lo'o lolomi fa'atete'e ata mafiafia i tua o le diaphragm sima ma fa'afeso'ota'i e fai ai se alalaupapa Wheatstone. Ona o le piezoresistive aafiaga o le piezoresistive resistor, o le alalaupapa e maua ai se laina eletise maualuga faailoilo faʻatusatusa i le mamafa ma faʻatusatusa foi i le voltage faʻafefe. O le faʻailoga masani e faʻavasegaina e pei o le 2.0 / 3.0 / 3.3 mv / e tusa ai ma vaʻaiga mamafa eseese.

3. Diffused silicon pressure sensor: O le mataupu faavae galue o le diffused silicon pressure sensor e faʻavae foi i luga o le piezoresistive effect. E ala i le faʻaaogaina o le piezoresistive effect principle, o le mamafa o le fua faʻatatau e galue saʻo i luga o le diaphragm (stainless steel or ceramic) o le masini, ma mafua ai ona maua e le diaphragm le micro-displacement faʻatusatusa i le mamafa o le ala, ina ia faʻatatau i le taua o le tetee. suiga sensori. O lenei suiga e iloa e ala i le eletise eletise, ma o se faʻailoga fua faʻatatau e fetaui ma lenei mamafa o loʻo liua ma gaosia.

4. Sapphire pressure sensor: Faʻavae i luga o le galuega faʻavae o le faʻalavelave faʻalavelave, o le silicon-sapphire e faʻaaogaina e avea o se elemene maaleale semiconductor, o loʻo i ai uiga e le mafaatusalia fua. O le mea lea, o le semiconductor sensor e faia i le silicon-sapphire e le mautonu i suiga o le vevela ma e lelei uiga galue e tusa lava pe maualuga le vevela. O le safaira e malosi le tete'e o le radiation; E le gata i lea, o le silicon-sapphire semiconductor sensor e leai se pn drift.

5. Piezoelectric pressure sensor: Piezoelectric aafiaga o le mataupu faavae galue autu o le piezoelectric sensor. E le mafai ona fa'aogaina le masini piezoelectric mo le fua fa'atatau, aua o le tau pe a uma le malosi i fafo e fa'asaoina pe a na'o le matasele o lo'o i ai impedance fa'aoga e le gata. E le o le tulaga lea i le faʻatinoga, o lea ua filifili ai e mafai e le piezoelectric sensor ona fuaina le mamafa malosi.
