Product Details Supplier Info More products

Kistler has introduced a range of single-axis and triaxial lightweight, miniature Piezobeam IEPE accelerometers with optional TEDS that are designed for the multi-channel modal and structural analysis of small or thin-walled structures, components and subsystems.

The accelerometers can also be used for full vehicle testing within automotive, aerospace, commercial aviation and general laboratory testing environments.

Both single-axis and triaxial models operate directly from an IEPE power source found in most FFT analysers, as well as from Kistler Piezotron power-supply couplers or any other industry-standard IEPE-compatible power source.

Units are ground-isolated when mounted with the optional twist clip or adhesive adaptor.
