3801A, Stud Mount Uniaxial Accelerometer
- ±50g to ±2000g Dynamic Range
- 10,000g Shock Protection
- Hermetically Sealed
- Gas Damping
- mV Output, DC Response
- Stud Mounting
The Model 3801A MEMS DC Accelerometer features a piezoresistive MEMS sensor within a rugged, welded hermetic package, designed to endure harsh conditions while providing precise acceleration measurements. This accelerometer is equipped with mechanical stops, ensuring over-range protection beyond 10,000g, making it exceptionally resilient to high-impact events. Available in a variety of ranges from ±50g to ±2000g, the 3801A is gas-damped to deliver a broad frequency response and optimal high-frequency attenuation. Additionally, it includes temperature compensation to maintain stable output across diverse operating environments. Its stud mounting design facilitates straightforward installation.
