7132A Series Accelerometer

Description: The Model 7132A is a miniature triaxial IEPE accelerometer available in ±10g to ±2000g dynamic ranges. The accelerometer features a hermetically sealed titanium construction with a 4-pin Microtech connector interface. The model 7132A incorporates stable piezo-ceramic crystals in annular shear mode which provide a flat frequency response up to >12kHz. The model 7132B offers identical performance with an integral cable option.
