MODEL 7130A ACCELEROMETERSPECIFICATIONSDIMENSIONS

Triaxial IEPE Accelerometer
Wide Bandwidth to 9kHz
Hermetically Sealed
Annular Shear Mode

The Model 7130A is a triaxial IEPE accelerometer
available in ±50g to ±500g dynamic ranges. Theaccelerometer features three independent welded stainlesssteel assemblies incorporated into a hard anodized
aluminum housing. The model 7130A incorporates a stablepiezo-ceramic crystal in annular shear mode, installed witha compression ring that eliminates the usage of epoxies
that can affect long term stability. The accelerometer hasan operating range of -55°C to +125°C and a flat frequency
response to 9kHz.
