The Model 3801A is a mV output piezo resistive MEMS accelerometer in a rugged welded hermetic package. 

The accelerometer incorporates mechanical stops for over range protection up to greater than 10,000 g. The model 3801A is offered in ranges from ±2 to ±2,000 g and is gas damped to provide a wide frequency response. 

The accelerometer is temperature compensated to provide a stable output over the operating environment.
