用于振动分析的加速度计选择

您好,我们正在构建一个用于机器状态监控的应用程序。为此,我试图找出具有以下规格的适当加速度计:(1)1.5至2 kHz的频率响应,(2)高ODR,越高越好,(3)模拟抗混叠滤波器, (4)至少14位的分辨率。在查看了不同的加速度计之后,我已经将LSM303AH和ISM330DLC归零(我们将只使用acc传感器)。你能否建议两者中哪一个优先于另一个(对于这个特定的应用)?或者,如果这些不合适,请您提出其他选择。
问候,
ANKUR

Hello, we are building an application for condition monitoring of machines. For this, I am trying to figure out the appropriate accelerometer with the following specs: (1) a frequency response of 1.5 to 2 kHz, (2) a high ODR, higher the better, (3) an analog anti-aliasing filter, and (4) a resolution of at least 14 bits. After looking at different accelerometers, I have zeroed-in on LSM303AH and ISM330DLC (we'll be utilizing only the acc sensor). Can you please suggest which among the two should be preferred over the other (for this particular application)? Or, if these are not the appropriate ones, could you please suggest other options.
Regards,
Ankur

我建议使用ISM330DLC,因为它有4kB,工作电压为1.71V至3.6V。
LSM303AH仅具有256平方FIFO,仅适用于1.8V。

I would suggest to use ISM330DLC because it has 4kB and works from 1.71V to 3.6V.
The LSM303AH has only 256-lvele FIFO and works only at 1.8V.

感谢Miroslav的建议。你也有可能找到
在ISM330DLC中实现了什么样的抗混叠滤波器?
最好的祝福,

Thanks Miroslav for your suggestion. Is it also possible for you to find
out what kind of anti-aliasing filter is implemented in ISM330DLC?
Best regards,

我明白,当然米罗斯拉夫。另外,我正在阅读数据表
ISM330DLC和LSM6DSL它们似乎都大致完全相同
规格。任何想法之间的重大差异是什么
这两个?只是想确保我们选择合适的传感器
我们的申请。
最好的祝福,

Sure Miroslav, I understand. Also, I was going through the data sheets of
ISM330DLC and LSM6DSL and they both seem to have mostly the exact same
specifications. Any idea what is the big/important difference(s) between
these two? Just want to ensure that we select the appropriate sensor for
our application.
Best regards,
Ankur
