Shock exciter Spektra SE-221

Shock exciter for testing and calibration of shock transducers as well as complete measuring instruments (measuring chain) according to ISO 16063-22. Allows the secondary calibration of shock sensors in very high precision and efficiency with shock amplitudes up to 200 000 gn. – depending on the choice of Hopkinson-bar. Typical applications can be found at accredited calibration laboratories, research and development, aerospace industry, sensor manufacturers or metrology institutes (NMI). The well-known SPEKTRA quality guarantees the performance of automatic calibrations with excellent repeatability of the sinusoidal shocks.
