Model 3028 Accelerometer
Piezoresistive MEMS
DC Response, mV Output
Low Cost
Screw Mounted Flange
The Model 3028
is a silicon MEMS
accelerometer in a Wheatstone bridge
configuration. It is packaged on a ceramic
substrate with a metal bracket which can
be used to bolt the sensor to the mounting
location. The accelerometer is offered in
ranges from ±2g to ±200g range and
provides a flat frequency response to
minimum 2000Hz. The silicon MEMS
sensor is gas damped and incorporates
over-range stops for high-g shock
protection.
For a similar accelerometer designed for
adhesive mounting, see the model 3022.
