聯(lián)系我時(shí)，請(qǐng)告知來(lái)自 儀表網(wǎng)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。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3079A是一款I(lǐng)EPE加速度傳感器/振動(dòng)傳感器，用于狀態(tài)與使用監(jiān)控系統(tǒng)，靈敏度10mV/g，頻響范圍1.1-5000HZ。
Expressly designed for use in Health and Usage Monitoring Systems (HUMS), the Dytran 3079A is an IEPE piezoelectric accelerometer, featuring a sensitivity of 10 mV/g with a frequency response of 1.1 to 5,000 Hz, packaged in a highly rugged stainless steel housing weighing 11 grams.
The distinguishing feature of model 3079A is the Dytran developed integral mounting bracket design, facilitating improved sensor performance while eliminating costs associated with separate mounting brackets. The miniature accelerometer is mounted within the bracket at the point where the cable and bracket are joined. This unique design also offers reduced mass, as compared to conventional sensors and mounting brackets. Model 3079A is hermetically sealed for reliable operation within high humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference.
