動(dòng)態(tài)壓力傳感器包含低壓測量、高壓瞬態(tài)測量。動(dòng)態(tài)壓力傳感器可以測量各種各樣的高強(qiáng)度聲壓和高水平動(dòng)態(tài)壓力事件。
哥倫比亞大學(xué)生產(chǎn)的動(dòng)態(tài)壓力傳感器也可以用作聲學(xué)傳感器（麥克風(fēng)）。它們被設(shè)計(jì)用來測量快速的壓力變化、浪涌和動(dòng)態(tài)爆炸。這些傳感器從低成本、小尺寸、輕量化到高壓（到10000磅/平方英寸）單元，采用全焊接結(jié)構(gòu)，具有極強(qiáng)的耐用性，使它們成為廣泛應(yīng)用的最佳選擇。
