1. Safety Instructions
•
To avoid permanent
semiconductor sensor in the small black box,
the maximum acceleration in any direction
must not be allowed to exceed 2000 times the
gravitational acceleration of the earth (2000g).
•
Do not allow the sensor element to fall from
any height greater 1.2 m onto a hard surface.
The ±25g accelerometer may only be used for
•
educational purposes.
The ±25g accelerometer is not suitable for safety-
related applications.
2. Description
Sensor box with
semiconductor accelerometer, which responds to
forces along its X-axis, for measuring the earth's
gravitational field (acceleration due to gravity) and
acceleration of bodies in general up to ±25g.
The direction in which the gravitational field of the
earth should be aligned (X-axis) is printed on the
accelerometer.
