Charge amplifier for piezo sensors. With one 25 mm x 5 mm piezo PVDF sensor and cables.
It comes with a 5V DC adapter, a PVDF sensor. a sensor connection cable, You need to use BNC cables to connect it to your oscilloscope.
Even though the output votlage is very high (V to 100's V) from piezo film sensor, the charges are quite low and the impedance of the piezo sensor is very high. Therefore, it is necessary to use a charge amplifier to amplify the signal so you can use oscilloscope to monitor the output.
