Accelerometer 3028Accelerometer 3028
The Model 3028 is a piezoresistive silicon accelerometer packaged on a ceramic substrate with a metal bracket which can be used to bolt the sensor to the mounting location. The accelerometer consists of a micro machined silicon mass suspended by multiple beams from a silicon frame. Piezoresistors located in the beams change their resistance as the motion of the suspended mass changes the strain in the beams. Silicon caps on the top and bottom of the device are added to provide over-range stops. |

This design provides for a very low profile, high shock resistance, durability and built-in damping over a wide usable bandwidth. For an accelerometer with an adhesive mount design, see the Model 3022. Please refer to the Models 3052 and 3058 for accelerometers with integral temperature compensation.
