ETA - Oberst Beam


The robust and easy-to-use clamping system makes it possible to fix the beams rigidly and to test several beams in a short time.

The acquisition system comes with a USB connection and is connected to the test bench by temperature resistant wires. The magnetic position sensor can adjust to different thicknesses of single or multi-layered beams. Finally, the magnetic exciter with adjustable position makes it possible to test single or multi-layer beams of different lengths.
