Find suitable SI units to work with a Vibration Sensor

In summary, we are working on an IOT project that involves using a wireless vibration sensor to gather data on different vibrations. The sensor measures in SI units of 'g' and can be adjusted to work with CNC machines by multiplying by a unit system's value for gravity. The sensor provides a spectrum of vibration levels and typically measures in units of m/sqrt(Hz). The manual also mentions the sensor has an Industrial Grade 3-axis Vibration Sensor with RMS, MAX, and MIN acceleration in 'g', which corresponds to the values 0.75, 0.72, and 0.69. There is a possibility to adjust the sensor to focus on certain frequency ranges to measure maximum vibration levels. It is important to also consider

We are working on an IOT project in which we are trying to learn about different vibrations of using Wireless Vibration Sensor
According to the manual, the wireless vibration sensor is giving the output while testing on CNC machine device

0.75, 0.71,0.69 whose SI units are in 'g'(which is acceleration due to gravity according to me ) but I am not aware of suitable SI units which will be useful to make it work with CNC machines.

Any suggestions on this will be a great help.

fraction of g is unit system independent. You can put it in a unit system by multiplying by a unit system's value for g, such as 9.8m/s^2.

As for how to make it useful - that is a matter of what you (or the machine) want to use it for.

There is typically no single "Vibration level" since you will always have a spectrum where the level is strongly frequency dependent.
You can of course talk about the maximum vibration level throughout some frequency range (say 0.1-100 Hz) ; and this then typically given in units of m/sqrt(Hz) (meters per square root Hertz); orr alternatively m2/Hz (same thing squared) .
A typical level for a low(ish) vibration system would be of the order of 1e-6 m/sqrt(Hz)

+1 to what Russ said.

The manual also says "Industrial Grade 3-axis Vibration Sensor with RMS, MAX and MIN acceleration in g". Are those the three figures you quoted 0.75, 0.72, 0.69?

I'm curious. Is cybersecurity a priority for your project?

Hello @CWatters
This value is RMS value only I 'll check with above-shared formulae also to get the desired values
 

What is a vibration sensor?

A vibration sensor is a device that measures the magnitude and frequency of vibrations in a given system. It is commonly used in scientific research, industrial applications, and consumer products.

Why is it important to find suitable SI units for a vibration sensor?

Using the appropriate units when working with a vibration sensor is crucial for accurate and consistent measurements. SI units, or the International System of Units, are the most widely accepted and standardized units of measurement in the scientific community.

What are the common SI units used with a vibration sensor?

The most commonly used SI units for vibration sensors are meters (m) for displacement, meters per second squared (m/s²) for acceleration, and Hertz (Hz) for frequency. Other units such as Newtons (N) for force and decibels (dB) for amplitude may also be used.

How do I convert non-SI units to SI units for a vibration sensor?

To convert non-SI units to SI units for a vibration sensor, you can use conversion factors or online unit converters. It is important to ensure that the conversion is done accurately to avoid errors in measurements.

Are there any limitations to using SI units with a vibration sensor?

While SI units are the standard for measurement, they may not always be the most practical or convenient units to use. In some cases, other units such as millimeters (mm) or micrometers (μm) may be more suitable for specific applications.
