Hi Bhaskar,

I’m not sure if I fully understand. Is ODR synonymous with sampling rate when talking about vibration analysis? If so I don’t understand how you arrive at this value. In your table, what is the difference between sps and Hz?

In the field of vibration analysis, this equation is commonly used:

**Ns = Fs X Ts**

where **Fs** is the maximum frequency of the vibration to be measured in Hz **X 2.56 (Nyquist Theorem)**,

**Ts** is the sampling time, usually the time required for the shaft to perform **10** **rotations**,

**Ns** is the number of samples required

If, for example, we want to measure the vibration caused by the bearings of a fan rotating at **1800** RPM, how would you set up the sensor considering that the vibration frequency of a defective bearing can be of the order of **20** **kHz**, by determining Fs, Ts and Ns as in the previous paragraph.

I would really appreciate if you could answer with the settings of the sensor taking into account the previous example as well as with the equation **Ns = Fs X Ts** so that I understand how to configure these sensors according to the real use cases that we have.

I know that my question is very picky. It is important to understand that we are working hard to get our customers to adopt this technology instead of traditional analysis equipment.And to do so, we must offer them sensors whose settings allow them to achieve the same result as their current vibration analysis equipment.

Thanks
