IEPE是指一种自带电量放大器或电压放大器的加速度传感器。IEPE是压电集成电路的缩写。因为由加速度传感器产生的电量是很小的，因此传感器产生的电信号很容易受到噪声干扰，需要用灵敏的电子器件对其进行放大和信号调理。IEPE中集成了灵敏的电子器件使其尽量靠近传感器以保证更好的抗噪声性并更容易封装。

美国Dytran的3049E是一款IEPE加速度传感器/振动传感器，灵敏度10mV/g，上行频响为10000Hz，钛合金外壳，应对潮湿和多尘的恶劣工作环境。

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.
