Supports for the accelerometers

An accelerometer should detect the vibrations transmitted to the hand by a vibrating object, such as a mechanical part or the handle of a tool. In both cases, you should not interfere with the normal operation and try to fix the sensor as close as possible to the center of the hand.

Often you need to use an adaptor on which to mount the accelerometer. This adaptor can be fixed to the vibrating object using strips, or held against it by the hand.

Here is some examples of supports to be used with the HD3023A2 accelerometer:

HD2030AC1

  

This adaptor is useful for small tools and anatomical handles, such as a drill.
Its small size and the possibility to fix it using a metallic or plastic strip, make it suitable for all measurements in which the interposition of the adaptor between the hand and the vibrating object is not possible or desired.

HD2030AC4

  

An adaptor to be pressed between the hand and the handle. The accelerometer is fixed in central position, between the middle finger and the ring finger or the forefinger and the middle finger.

Suitable for anatomical handles, even non cylindrical and small.
To keep it in place, you can fix it to the handle using fabric strips.

HD2030AC2

  

An adaptor to be pressed between the hand and the handle. The accelerometer is fixed laterally, to the left or right of the hand. Suitable for large cylindrical handles.
The measurement should be repeated by positioning the accelerometer on both sides of the hand and then calculating the average value.

 

 

The HD3200B5T monoaxial sensor, suitable for shock measurements, can be combined to the HD2030AC3 support in stainless steel:

 

HD2030AC3
An adaptor to be pressed between the hand and the handle. The accelerometer is fixed laterally, to the left or right of the hand.
Suitable for large cylindrical handles and for accelerometers with built-in screw. The measurement should be repeated by positioning the accelerometer on both sides of the hand and then calculating the average value.
Suitable for accelerometers with built-in screw (e.g. HD3200B5T).
