5g Accelerometer U11363

Instruction sheet

07/07 Hh

1. Safety instructions

• Never exceed the maximum acceleration of

1500 times gravitational acceleration in any di-

rection, to avoid permanent damage to the

semiconductor built into the small black box!

• The maximum height from which the sensor

can survive dropping onto a hard surface is 1.2

• Only use the accelerometer 5-g for educational

purposes!

The 5g accelerometer is not suitable for safety-

related applications.

2. Description

Sensor box with permanently connected semicon-

ductor acceleration sensor, Z-axis sensitive, for the

measurement of gravity and the general accelera-

tion of masses up to ±5 x g.

The effective axis (Z-axis) is marked with an arrow

and the label “Earth’s Gravity Field” on the accel-

eration sensor.

“Capacitive" method of measurement (g-cell) with

built-in signal linearisation, low-pass filtering,

temperature compensation and automatic self-test.

The sensor box is automatically detected by the 3B

NETlab

interface.

3. Scope of delivery

1 Sensor box with permanently connected accel-

eration sensor, cable length 2 m.

1 Velcro strip, 500 mm long, 20 mm wide, self-

adhesive

1 8-pin miniDIN connecting lead, 60 cm length
