美國Dytran
Dytran公司由當今總裁Nick Change成立于1980年，地點位于紐約布法羅。Nick豐富的壓電式傳感器設計經驗可追溯到1959年，從那時候開始任職于著名的壓電式傳感器制造商。不久，便在布法羅大學取得電子工程學位。1980，Nick正式成立Dytan公司（Dytran的由來就是dynamic and transducers兩個詞前面的字母組成的)
 主要客戶群：航空、航天、船舶、兵器、核工業、水力、電力、輕工、交通、 冶金、石油、化工、造紙、礦山、核電站、機械、汽車、建筑、橋梁、飛機、食品加工、印刷、制藥等各個行業 主要產品包括壓電加速度傳感器、動態力傳感器、動態壓力、力錘和信號調節儀。
Dytran 于1980年在美國成立。目標以研制倉新傳聲器的方案去迎合不同行業的測試和測量要求。
主要產品：加速度傳感器、力學傳感器、壓力傳感器、電子儀器、脈沖力錘和系統、阻抗頭等等。Dytran傳感器，設計針對不同行業的應用，譬如航空業、汽車制做業、醫學、實驗室、商業和工業等。
 Dytran was founded in 1980 by current company president Nick Change, in Buffalo NY. Nick’s vast experience in piezoelectric sensor design dates back to 1959. He began his career in piezoelectric sensors working with a well-known sensor manufacturer in the Buffalo, New York area as a draftsman. He later went on to earn his bachelors degree in electrical engineering from The University of Buffalo. His career path took him to the eventual presidency of two major players in the piezo world. In 1980 Nick had the intestinal fortitude to form his own company (Nick named the company Dytran by combining the words dynamic and transducers). And so Dytran was born in the proverbial basement of Nick’s home in a suburb south of Buffalo. As they say, the rest is history!
