Miniature, Stud Mount

The Model 7109A is a miniature stud mount IEPE shock
accelerometer available in ±5,000g to ±20,000g ranges.
The accelerometer features a welded hermetic stainlesssteel construction with an integral cable for electricalconnection. The model 7109A incorporates a stable piezoceramic crystal in annular shear mode with outstanding
linearity for shock measurements. The accelerometer hasan operating range of 0°C to +85°C and a flat frequency
response to >10kHz.
