IEPE是指一種自帶電量放大器或電壓放大器的加速度傳感器

詳細(xì)介紹

IEPE是指一種自帶電量放大器或電壓放大器的加速度傳感器。IEPE是壓電集成電路的縮寫(xiě)。因?yàn)橛杉铀俣葌鞲衅鳟a(chǎn)生的電量是很小的，因此傳感器產(chǎn)生的電信號(hào)很容易受到噪聲干擾，需要用靈敏的電子器件對(duì)其進(jìn)行放大和信號(hào)調(diào)理。IEPE中集成了靈敏的電子器件使其盡量靠近傳感器以保證更好的抗噪聲性并更容易封裝。

美國(guó)Dytran的3049E是一款I(lǐng)EPE加速度傳感器/振動(dòng)傳感器，靈敏度10mV/g，上行頻響為10000Hz，鈦合金外殼，應(yīng)對(duì)潮濕和多塵的惡劣工作環(huán)境。

The Dytran 3049E is a general purpose IEPE accelerometer, available with a sensitivity of 10 mV/g and an upper frequency response of 10,000 Hz. Featuring a ceramic shear sensing element packaged in a lightweight titanium housing, model 3049E is hermetically sealed for reliable operation in high humidity and dirty environments and base isolated to avoid EMI/ground loop interference.

Model 3049E is part of the 3049E series of accelerometers, which offer the same high reliability performance with various mounting options. The Dytran models 3049E and 3049E2 feature a 10-32 mounting stud, while models 3049E1 and 3049E3 offer adhesive mounting capabilities.
