RFDA LT80

DESCRIPTION

The RFDA LT80 measurement system is designed to perform impulse excitation measurements in a temperature range from -80°C up to +140 °C. Typically an air atmosphere is used, but a more controlled atmosphere can be obtained with an optionnal inert gasflow. Measurements can be performed in predefined intervals during heating and cooling (1-5 °C/min). The results of these measurements are a plot of frequency, Young’s modulus, Shear modulus, Poisson’s ratio and damping (internal friction) versus temperature. Measurements are performed continuously in predefined intervals during the heating and cooling phase. The adjustable positioning of the excitation system and the front loading of the sample guarantee an optimal sample configuration and manipulation.
