7134A Series Accelerometer

Description: The Model 7134A is a true case isolated triaxial IEPE accelerometer available in ±50g to ±500g dynamic ranges. The accelerometer features three internally shielded accelerometer assemblies for superior noise isolation. The assemblies are installed in a hermetically sealed light weight Titanium housing with a 4-pin Microtech connector interface. The model 7134A features piezo-ceramic crystals in annular shear mode which provide a flat frequency response up to >9kHz.
