Dareemaha CA202 waxa uu leeyahay shay cabbira polycrystalline shearmode asymmetrical ah oo leh dahaarka gudaha kiis austenitic ahama birta ah (guri). CA202 waxaa lagu rakibay fiilo sanqadh hoose ah oo isku xidhan kaas oo ay ilaalinayso tuubada ilaalinta aan-birta lahayn ee dabacsan (leaktight) kaas oo hermetically alxanka loogu xidhay shidma si uu u soo saaro isku xidhka dareeraha. Xawaare mitirka piezoelectric CA202 waxaa lagu heli karaa noocyo kala duwan oo jawiga warshadaha kala duwan: Noocyadii hore ee lagu rakibay jawiga qarxi kara (meelaha halista ah) iyo noocyada caadiga ah ee loo isticmaalo meelaha aan khatarta ahayn. Xawaaraha-xawaaraha piezoelectric CA202 waxaa loogu talagalay kormeerka iyo cabbirka gariir warshadaha ee culus. Codsiyada gaarka ah, la xiriir wakiilka Meggitt ee degaankaaga.
