概述

Expressly designed for use in Health andUsage Monitoring Systems (HUMS), the Dytran model 3079A is an IEPEpiezoelectric accelerometer, featuring a senSITIvity of 10 mV/g with afrequency response of 1.1 to 5,000 Hz, packaged in a highly rugged stainlesssteel housing weighing 11 grams.

The distinguishing feature of model 3079Ais the Dytran developed integral mounting bracket design, facilitating improvedsensor performance while eliminating costs associated with separate mountingbrackets. The miniature accelerometer is mounted within the bracket at thepoint where the cable and bracket are joined. This unique design also offersreduced mass, as compared to conventional sensors and mounting brackets. Model3079A is hermetically sealed for reliable operation within high humidity anddirty environments, as well as case isolated to avoid EMI/ground loopinterference.

加速度传感器，包括由硅膜片、上盖、下盖，膜片处于上盖、下盖之间，键合在一起；一维或二维纳米材料、金电极和引线分布在膜片上，并采用压焊工艺引出导线；工业现场测振传感器，主要是压电式加速度传感器。其工作原理主要利于压电敏感元件的压电效应得到与振动或者压力成正比的电荷量或者电压量。目前工业现场典型采用IEPE型加速度传感器，及内置IC电路压电加速度传感器，传感器输出与振动量正正比的电压信号。

加速度传感器是一种能够测量加速力的电子设备。加速力**是当物体在加速过程中作用在物体上的力**好比地球引力，也**是重力。加速力可以是个常量。加速度计有两种：一种是角加速度计，是由陀螺仪（角速度传感器）改进的。另一种**是线加速度计。

应用

2    High frequencyaircraft/airframe vibration measurements

3    Health and Usage MonitoringSystems (HUMS)

4    Rotor, Track and Balance(RTB)

5    Transmission vibrationmeasurements

通过测量由于重力引起的加速度，你可以计算出设备相对于水平面的倾斜角度。通过分析动态加速度，你可以分析出设备移动的方式。但是刚开始的时候，你会发现光测量倾角和加速度好像不是很有用。但是，现在工程师们已经想出了很多方法获得更多的有用的信息。
