Piezosystem jena has expanded its d-Drive line of digital piezo amplifiers with the 30DV50 OEM module. The digital piezo nanocontroller offers high positioning accuracy and comes with an autocalibration routine and automatic sensor identification. All values of the actuating system, such as capacitance measurement, resonant frequency and motion, are automatically stored in the amplifier. It can be used with strain gauge, LVDT or capacitive feedback sensors without modification. The digital signal processor runs at 64 MHz, with a total sampling rate of 20 µs. The amplifier operates from 10 to 30 VDC and achieves 20-bit resolution.
