Description
Strain gauge (Two-channel tensometric measuring instrument) is a device intended for measurement of deformation of resistance strain gauges which can be caused by change of force, loading, twisting moment, pressure, weight, vibration and other mechanical and physical parameters.
Strain gauge can be used both independently and together with A-Line 32D acoustic emission (AE) system by means of signal injection into the relative system parametric input.
