Hand Arm Vibration Transducer Mounting
If your Excieo meter was purchased with a Hand Arm Tri-Axial Accelerometer
(abbreviated to HARM) then you will have been supplied with a HARM mounting
block, retaining stud and Allen key. The mounting block can be attached to the
HARM accelerometer using the supplied stud and tightened using the supplied
Allen key. The mounting block can then be mounted to the vibration source
using hose clamps or plastic ties. If plastic ties are used it is recommended that
they are tightened using a tie tensioning tool. Attaching devices such as clamps
and the accelerometer to hand held devices may alter the mass of the vibration
source and will inevitably slightly alter the vibration emitted from the device, it is
therefore recommended to keep the mass of hose clips or clamps to a
minimum.
Other mounting possibilities to mount the accelerometer to the vibration source
are tapping a stud into the vibration source and attaching the accelerometer to
the stud. Alternatively the stud may be adhered to the device rather than
tapped with an adhesive that dries rigid. Castle Group Ltd can supply a glue and
stud pack if required, (order code KD1215).
Whole Body Vibration Transducer Mounting
No definitive methods can be realized for mounting the seat pad as many
permutations are possible; it is only possible to highlight suggestions.
The seat pad could be mounted on the seat of the vibration source with the user
sat on the seat pad. The pad could also be taped to the seat to stop it moving if
required.
The seat pad could be taped to the back of the seat or to the operator if
required. If the latter option is employed it is imperative that all aspects of safety
regarding the operator are considered and adhered to.
Position the seat pad on the floor of the vibration source ensuring that the pad
is either fixed down possibly using tape or an object over it to keep it in position.
In all cases where the seat pad is used, ensure that the pad is kept in contact
with the vibration source at all times and ideally taped in position to stop it
moving.
