Nanopositioning & Scanning Systems Weight of strain gauge sensormodels is 1 to 3 g higher than open-loop models. The typicalweight of a 1 m voltage cablewith LEMO connector is 19 g (VH) and 12 g (VL). The typical weight of a 1 m sensor cable with LEMO connector is 21 g. Average electrical current (sup-plied by the amplifier) required to drive a piezo actuator per unit frequency and unit dis- placement (sine wave opera- tion, open-loop—up to 50% more in closed-loop operation). To find out if a selected amplifier can drive a givenpiezo actuator at, say, 100 Hz with 5 µm amplitude, multiply DOCC by 100 x 5 and check if the result is smaller or equal to the output current of the select-ed amplifier.
