Small 3 Axis Piezoresistive Accelerometer Vibration Measurement
Sensors Piezoresistive VS3015
VS3015 Vibration Measurement Sensor is a compact, factory
calibrated 3 axis device based on piezoresistive technology. Its
housing has a flat design for easy screw mount. Due to its low mass
this model is perfect for testing light weight structures.
VS3015 Accelerometer is designed for high performance applications.
The accelerometer incorporates a piezoresistive MEMS sensing
element providing outstanding long-term stability. All three axes
meet their positive direction in the center of the sensor housing.
The small and cube housing can be mounted on different sites. Its
ranges is ±15g. Signal amplified versions are optional.
VS3015 enjoys high reliability, high stability, high accuracy, low
temperature drift, and strong adjustment in harsh environment.
It is an ideal option for auto measurement, inertial navigation,
aircraft safety system, earthquake monitor, tilt, speed and
position inertia, test platform of vibration and shocking, etc.

How do I mount an accelerometer?
The mounting of an accelerometer affects its frequency response.
The mounted natural frequency is dependent directly on the
stiffness of the mounting. The higher the stiffness the more the
mounted natural frequency approaches its maximum. The least stiff
mounting of an accelerometer is magnetic mounting and the highest
stiffness is using a high tensile setscrew tightened to the correct
torque mounted on a hard flat surface. Other mounting methods come
in between these two extremes.
It is important to ensure that the site chosen for the
accelerometer is ground flat for at least an area larger than the
base of the accelerometer. A slight smear of Silicone grease will
ensure a stiff bond between accelerometer and structure.
When using a mounting stud it is important to ensure that the stud
does not bottom out in either the base of the accelerometer or the
drilled location hole. High tensile strength set screws that have a
shoulder will prevent this eventuality from happening.
