3.6.1
PICA Piezo Actuators
P-2x5 are PICA preloaded high-load piezo actuators for static and dynamic applications. They
have a submillisecond response time and subnanometer resolution.
The piezo actuators have a friction-free, preloaded PICA Power piezo ceramic that is integrated
in a stainless-steel housing. The high load capacity and internal preload makes them ideal for
applications such as precision manufacturing and active vibration damping.
3.6.2
Strain Gauge Sensors (SGS)
Strain gauge sensors derive the position information from their expansion. A strain gauge
sensor consists of an electrically conductive film, the resistance of which changes with the
strain. Strain gauge sensors are attached to the actuator and measure its displacement. The
sensors are equipped with a full-bridge circuit that is insensitive to thermal drift, and assure
optimum position stability in the nanometer range.
