What is important to know about cryogenic applications?
The piezo effect itself depends on the temperature. The effect decreases with decreasing temperature at a rate of approx. 0.4% per Kelvin. In the temperature range of liquid nitrogen (ca. 77 K) the expansion due to the piezo effect will be about 20-30% of the expansion at room temperature.
In principle, piezoelectrical actuators can work at very low temperatures, such as the temperature of liquid Helium (4 K).
All systems ordered with the vacuum compatible option can be used in the cryogenic region. Please note that the original motion of the PZT is reduced when used at low temperature.
