SE-21
Powerful high-frequency vibration exciter as part of the SE-2X series with cube-shaped ceramic armature for excitation of all DUT axes. With its electrodynamic drive system, the SE-21 offers a very wide frequency range with low transverse motions. A high payload, simple operation in a climatic chamber (as SE-21T) and the many extensions enable the SE-21 to be used as a multi-tool for testing, characterizing and calibrating vibration sensors or smaller electronic devices.
