Simply put, accelerometers are devices that calculate the change in force of acceleration and speed that is instilled by gravity. However, these devices have found their use in a variety of industrial applications that has further led to the development of several types that are suited for different purposes. Therefore, it is important to keep in mind a few considerations before you purchase a accelerometer for your desired application. Whether You Need Analog or Digital Accelerometer?
This depends on the hardware used by the equipment. While analog accelerometers have a continuous voltage output that is proportional to the acceleration, digital accelerometers use pulse width modulation. The bottom line here is that a completely analog based circuit will require analog accelerometers and a digitally fed circuit will require digital accelerometers.
Single or Multiple Axes?
Though in most cases, two axes will prove sufficient, a 3-d project will definitely require an accelerometer that is of 3-axes. However, if 2 axes accelerometer is mounted at right angles, you can still use them in 3-d projects instead of a 3-axes accelerometer.
What Bandwidth?
Bandwidth deals with reliable and accurate readings. If you increase the frequency of readings, you will automatically need an accelerometer that comes with greater bandwidth parameters.
Hopefully, above questions have cleared your mindset on how to choose accelerometers. You can buy online accelerometer in Australia from a plethora of e-commerce portals that also ensure door-step delivery.
