RFDA LTVP800
The LTVP800 system is designed to perform impulse excitation measurements at temperatures from -50 °C up to 800 °C in vacuum (10-4 mbar). Measurements can be performed in predefined intervals during heating and cooling (1-60 °C/min) in order to determine the elastic properties and damping as function of the temperature. The LTVP800 system is equipped with a turbomolecular vacuum pump to perform measurements in a controlled vacuum atmosphere and a laser vibrometer to detect the vibration signal.
