7130A Series Accelerometer

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