MODEL 3255A ACCELEROMETER

SPECIFICATIONS

 PC Board Mountable Accelerometer

 Amplified Output

 Temperature Compensated

 High Over-Range Protection

The Model 3255A is a signal conditioned board mountable

MEMS accelerometer available in ±25g to ±500g ranges.

The package can be mounted in one of two orientations,

allowing the measurement axis to be either parallel or

perpendicular to the mounting surface without the use of

costly brackets. The accelerometer incorporates integral

temperature compensation and offers a flat frequency

response from DC to 1500Hz.

FEATURES

 ±25g to ±500g Ranges

 Three Axis Mounting Options

 Surface Mount Package

 DC Response, Gas Damping

 Hermetically Sealed

 5Vdc Excitation

APPLICATIONS

 Impact & Shock Testing

 Vibration & Shock Monitoring

 Embedded Applications

 Transportation Measurements
