Measurement Specialties Inc., Hampton, VA, offers the Model 1007214 amplifier that lets you evaluate applications for piezo film sensors. The amplifier has selectable charge or voltage mode and active high- and low-pass filters. Sensitivity control is ±40 dB (voltage mode) and 0.01–1000 mV/pC in charge mode. The amplifier provides full frequency response control over piezoelectric sensors, independent of their capacitance or impedance. Applications include machine vibration, low-frequency dynamic strain, pyroelectric signals, audio band/acoustic signals, and traffic sensors.
