3801A Series Accelerometer

Description: The Model 3801A is a mV output piezoresistive accelerometer in a rugged hermetic package. The accelerometer incorporates mechanical stops for over-range protection up to 10,000g. The Model 3801A is offered in ranges from ±2 to ±2000g and is gas damped to provide a wide frequency response. The accelerometer is temperature compensated to provide a stable output over the operating environment.

Features:
• ±2g to ±2000g Dynamic Range
• 10,000g Shock Protection
• Hermetically Sealed Sensor
• Gas Damping
• mV Output
• DC Response
• Stud Mounting
