Sercel Ma Tronic 'Au mo Up MEMS Faʻavae Geophones

Sercel ma TRONIC'S Microsystems, na galulue faʻatasi mo le gaosiaina o se augatupulaga fou o seismic sensors, poʻo geophones, faʻavae i luga o le MEMS. Fuafuaina e CEA Leti, o le 0.1µg iugafono fua faʻataʻamilomilo afifi i lalo lagona gaogao ua optimized ma industrialized e TRONIC'S Microsystems.
O Geophones e aofia ai se tasi o oloa taua a le Sercel (F), o le taʻitaʻi o le lalolagi i mea e faʻaaoga e seismic mo le suʻesuʻeina o le suauʻu ma le kesi. O ni masini e matua maaleale, e fuaina e le geophones le atagia mai o galu malie, na lafoina i luga o le fanua, i vaega eseese o le eleele (tagaʻi i le ata 1). O faʻamaumauga e faʻaaoga e tusia ai faʻafanua o le fanua faʻafanua faʻailoa nofoaga ma nofoaga o le suauʻu ma kesi faʻasao.
Geophones, e ui o le taugata eletise elemeni (vaʻai le ata 2), na fai si mamafa ma faigata ona e manaʻomia e fesoʻotaʻi i uaea i le ogatotonu gaosi iunite. O suʻesuʻega faʻaonapo nei o suauʻu e manaʻomia ai le mama, sili atu fofo feaveaʻi e mafai ona sili atu le saʻo.

MEMS faʻavae geophone
Na faʻaalu e Sercel le tele o tausaga e galulue ai ma le CEA Leti (F), e faʻaali ai le agavaʻa ma le fausiaina o le GeEMhone faʻavae MEMS. O le galulue faʻatasi na mafua ai se faʻataʻitaʻiga o se matua laʻititi ma mama laʻititi e faʻatumuina le geophone (vaʻai le ata 2 ma le laulau 1).

O le faʻataʻitaʻiga na oʻo i le manaʻoga ogaoga gaioiga: o se iugafono i lalo i le 0.1µg, itiiti ifo i le tasi miliona o le lalolagi kalave, i luga o le tele o +/- 100mg

Peitai, o se tasi o luitau sili ona tele na faataatia i le siitiaina o le MEMS-faavae fofo mai le fale suesue i le laina gaosiga. MEMS moni leai ni tulaga masani gaosia faiga ma i ai matua manaʻomia afifiina manaʻoga ma faigata laʻitiiti faʻapitoa suʻesuʻega taualumaga. O le mea lea na manaʻomia ai e Sercel se fale gaosi oloa MEMS tuʻufaʻatasi e mafai ona suia lona MEMS manaʻoga i se oloa gaosi faʻatuatuaina.

Geophone alamanuia
O le poto masani i le gaosiaina ma le gaosiaina o aga masani MEMS accelerometers, TRONIC'S Microsystems (F) na faʻatautaia foi poloka fale o Sercel's geophone tekonolosi.

O le kamupani maualuga-iuga tu MEMS gaosiga pisinisi pisinisi sa faʻapitoa foi talafeagai i Sercel's gaosiaina manaʻoga. O le mea lea o kamupani e lua na ofi atu i se paʻaga pisinisi

Amata mai i faʻataʻitaʻiga, Tronic's optimized le masini ma agavaʻa i lana faʻapitoa faʻagasologa ma lagona gaogao afifi metotia. O le kamupani gaosi Farani na ia mautinoa le muamua faʻasologa kilivaina i le amataga o le 2003 ma o le aso na tuʻuina mai afifiina ma faʻataʻitaʻia vaega o le geophone (vaʻai le ata 3) na tuʻufaʻatasia e Sercel i fou numera numera.

Vacuum afifi mo MEMS
Ina ia mafai ona faʻaititia le pisapisao pisapisao luga o le fausaga ma ia oʻo i le manaʻomia tulaga ausia, TRONIC'S encapsulate le silicon microstructure i lalo o se maualuga maualuga lagona gaogao siosiomaga i se LCC afifiina. Lenei afifi faʻatagaina le MEMS geophone e sili atu i le Q vala o le sili atu i le 10.000 (fuafuaina lagona gaogao i le tele o 1mTorr).

Laʻititi ma mama, o le lagona gaogao afifi MEMS geophone e oʻo lava i isi faʻaupuga taua o le tuʻufaʻatasiga geophones (vaʻai le laulau 1).

I se faʻaopopoga, 3 MEMS geophones mafai foi ona tuʻufaʻatasia faʻatasi i se laʻititi lava avanoa ma lana numera faaeletonika aveʻesea nisi o uaea na manaʻomia muamua. O le fou MEMS faʻavae geophone o lea faʻafaigofieina le logistic mo Sercel tagata faʻatau ao faʻatagaina 3 vaega fuaina ma le maualuga maualuga malosi.

E ala i lenei galulue faʻatasi, TRONIC'S Microsystems ua faʻamaonia atili lona agavaʻa e suia aganuu MEMS manatu i faʻatuatuaina maualuga gaioiga oloa mo demading talosaga.
