Kei roto i te pūoko CA202 he huānga ine polycrystalline hangarite me te kirikiri o roto i te pouaka kowiri tira austenitic (whare). Ko te CA202 he mea whakauru ki te taura haruru iti-iti e parea ana e te ngongo whakamarumaru kowiri tira (leaktight) e herea ana ki te pukoro hei hanga i tetahi huihuinga riihi hiri. Kei te waatea te CA202 piezoelectric accelerometer i roto i nga ahuatanga rereke mo nga taiao ahumahi rereke: Tuhinga o mua mo te whakaurunga i roto i nga waahi ka pupuhi (nga waahi morearea) me nga putanga paerewa mo te whakamahi i nga waahi kore. Ko te CA202 piezoelectric accelerometer kua hangaia mo te mahi taumaha-maha te aro turuki i te wiri me te ine. Mo nga tono motuhake, whakapaa atu ki to mangai Meggitt o to rohe.
